There are dozens, maybe even hundreds, of options when looking for a battery maintainer for your car, truck, boat, ATV or other vehicle. It can be confusing to choose among all those options, especially when there are many different approaches to this seemingly simple task. For many reasons, we’d say that PRO-LOGIX battery charger/maintainer products deliver the most beneficial maintenance routines on the market today, and in this month’s article, we are going to lay out the reasons why we feel this way.

The entire point of battery maintenance is to keep your batteries in good shape while they are not being used, so they are ready when you next want to drop the boat in the water or take old Betsy out for a cruise. In addition, the bigger goal is to get longer life from your batteries so you maximize your investment and save money in the long run. Every aspect of the PRO-LOGIX approach to battery maintenance is designed to improve battery health, increase reserve capacity and enable vehicle owners to get more from their battery investment.

We could probably provide 20 plus aspects of the PRO-LOGIX approach that support the above goals, but we are going to focus on six specific aspects that we think are the most important:

  1. Optimized Charge Routines for Different Battery Types
  2. Automatic Operation that Responds to Each Battery’s Needs
  3. Exercise is the Key to Health – Trickle Charging is a Dirty Word
  4. Temperature Compensation
  5. Effective Charging of Totally Dead Batteries
  6. The Ability to Overcome Power Outages

Optimized Charging Routines for Different Battery Types

This is critical when it comes to a battery maintenance option. By definition, a battery maintainer is going to see its most common service in long term charging situations. Your battery is going to be significantly exposed to the maintainer and its charging profile. This makes the maintenance charging profile far more critical than in a standard charger, which might be used once or twice a year on any given vehicle and for just a few hours at a time, rather than days or weeks at a time.

PRO-LOGIX chargers have distinct settings for each battery type serviced and are capable of servicing a wide variety of battery types, including Flooded, AGM, Spiral Wound, Gel Cell, Marine, Deep Cycle and LiFePO4 Lithium batteries (battery types serviced vary by model). This is really important no matter what type of batteries you have, but is especially important if your vehicles utilize batteries other than standard flooded batteries. For instance, if you have several AGM batteries, you need a maintenance option with an AGM-specific charging routine. AGM batteries have specific requirements when it comes to the charge profile and are very sensitive to overvoltage, which can cause deterioration of battery health.

Many maintainers don’t require you to select a battery type. While convenient, the problem with a maintainer that is designed this way is that it usually uses a generic, “safe” routine that won’t harm any lead acid battery type, but is not optimized for any one battery type. This means that it isn’t dialing in its routine and is often short charging batteries in order to avoid overcharging them. Over time, exposure to a sub-optimize charging routine can degrade, rather than improve, your battery’s health and longevity. For instance, you are likely undercharging flooded batteries with such a charger, which can lead to sulfation build-up, which saps a battery’s health and reduces its longevity.

Automatic Operation that Responds to Each Battery’s Needs

PRO-LOGIX battery maintainers utilize an advanced, automatic charging routine that responds to the specific needs of each battery charged to deliver an optimized charge and maintenance every time. Effectively, this means that the charger is going to adjust its operation based on the way the battery under charge is receiving the energy delivered by the maintainer. If the battery shows signs of sulfation, PRO-LOGIX charger/maintainers will automatically shift to battery repair mode and then resume normal charging when the battery accepts the energy in a more normal way. Similarly, if a battery is heavily discharged at the start of the charging cycle, PRO-LOGIX will automatic shift to a soft start mode to safely and beneficially bring the battery’s voltage to a more normal range and then resume standard charging. In the end, the goal is to deliver energy to the battery in the most beneficial way, regardless of size, type, condition or state of charge.

Exercise is the Key to Health – Trickle Charging is a Dirty Word

Let’s start with the second part of the above statement. Trickle charging (float charging) is how it was done for decades: bring the battery to full charge and then hold the voltage (usually around 13.2V). We believe that this approach is flawed on several levels. First, we think it doesn’t do much for battery health over time and, second, we think that it has a tendency to contribute to dried out batteries in extended maintenance situations. There’s a better way.

The PRO-LOGIX enhanced maintenance process has two key stages that, we’d say, are both unique to us and very beneficial for batteries under extended service. The first unique aspect of the PRO-LOGIX approach is that, upon reaching a full, complete charge, we put the battery into a rest phase. We don’t want the battery to be constantly under service. It isn’t necessary and it isn’t beneficial. Instead, we more closely mimic the way a battery is used when the vehicle is in service, with periods of activity and periods of rest. A known good battery will not self-discharge in just a few days, otherwise we’d see hundreds of jump starters in use every time we entered an airport parking lot. This rest phase is what makes PRO-LOGIX far less likely to contribute to drying out batteries in extended charging and contributes to longer battery life. The second unique aspect of the PRO-LOGIX approach is that, when the battery exits the rest phase, it enters an exercising phase before going through the next charge cycle. The exercise phase puts a load on the battery, simulating a starting event, which allows us to get a full, deep charge into the battery in the next charging cycle, which occurs immediately upon completion of the exercising phase. We believe that this rest-exercise-full charge cycle is far more beneficial for all battery types than a basic trickle charge.

Temperature Compensation

In our introduction to this article, we stated that every aspect of the PRO-LOGIX approach to battery maintenance is designed to improve battery health, increase reserve capacity and enable vehicle owners to get more from their battery investment. Temperature compensation is a great example of us walking our talk. It costs more and makes the product more complex, but you really can’t give a battery what it truly wants if you aren’t temperature compensated. Put simply, a colder battery wants more energy and a hotter battery wants less energy. The world isn’t a constant 70˚F and neither are your batteries. To get the most out of your battery maintenance efforts, you need a charger/maintainer that adjusts its charging routine based on battery temperature.

Effective Charging of Totally Dead Batteries

Just as you need a charger that can handle different battery types, different battery conditions and different temperatures, you need a charger/maintainer that can manage the occasionally totally dead battery. It sounds pretty basic, but many smart chargers and maintainers can only manage 12 Volt batteries with a state of charge above a certain threshold voltage, be it 1V, 3V, 5V, etc. The higher the threshold, the more likely you are of running into a situation where your charger cannot charge your battery. That’s a problem, one which we call The Dead Battery Dilemma, as in, “I bought a charger to charge my dead battery, but my battery is so dead that my charger doesn’t work!” But, that’s never a problem with PRO-LOGIX. All PRO-LOGIX chargers and maintainers incorporate a Forced Start routine where, assuming the only issue is that the battery is stone cold dead and all your connections are correct, you can hold down the START/CHARGE button for 3 seconds and force the charger to start charging. This is immensely helpful and time saving.

Ability to Overcome Power Outages

Several PRO-LOGIX charger/maintainer models (PL2140, PL4020, PL4050) incorporate our Recovery Mode (RM) technology to enable the charger to overcome power outages. On models so equipped and set to RM on (varies by model), the charger will remember its last charging mode when power is interrupted and resume charging under those settings when power is restored. This is a really big deal if your baby is charging in the third bay on a cold February day and you are down south living the snowbird lifestyle. With PRO-LOGIX, you can rest assured that, when power resumes, your battery is getting when it needs, without human intervention.

– the Complete Package

Compare these six aspects of PRO-LOGIX battery maintenance against the competition and you will see that not all charger/maintainers are created equal. PRO-LOGIX is not only better for your battery, but will save money by extending the useful life of your batteries and ensure your vehicles and toys are ready for action when you are.

Many of us are putting away boats, PWC, ATV’s, bikes and our fun vehicles for the winter season. Make sure to not only use a maintainer, but carefully select a maintainer that is best for your battery. With our unique and beneficial approach, many PRO-LOGIX customers report getting additional years of battery life and, most importantly, are not automatically replacing the batteries every spring. Choosing PRO-LOGIX is the smart solution for virtually any battery maintenance need.

    1. Brian – Our products can be found in a variety of outlets, including independent auto parts stores, NAP, Carquest, Auto Value, Bumper to Bumper, as well as numerous online outlets. Thanks, Jim from Clore Automotive

    2. I have had your charger for a couple years, did not realize how beneficial it really can be I can get as much as 10 years on a kept battery

  1. So disappointed in Hemmings Motor News. Ran this as though it were an information article, when it’s nothing more than an advertisement. Shame on them!!

    1. Andy – We’re sorry that this wasn’t what you were expecting. Please let us know if we can answers any questions, though. Thanks, Jim from Clore Automotive

    2. Andy, I got sucked in also thinking it was a story from Hemmings. Then I went back and it does say”SPONSORED PRODUCT SHOWCASE”. It is our fault for not reading the print.

    1. Ok sour puss. Did you not learn anything from reading this?? Yes there is a product being sold here. You do not need to buy it, however, if you did then you would be so much better off with you knowledge. Isn’t an educated consumer the best customer. Yessssss!!!! There you go. I personally will say thank you and that this product is the best. Hopefully others will realize the benefits and reap the rewards. Enjoy all the toys when you want to as you expect them to be, this is a short and long term key to that.

  2. I was glad to see this article as it addresses the restoration of a dead battery.

    I have a 2016 Mercedes with the start stop function hence it needs a separate battery ( in the tank) for the computers. Since I out of country for several months at a time without an electrical outlet in the condo garage, the battery goes flat and the MB ANSWER IS CHANGE THE BATTERY WE CAN NOT RECHARGE IT!. THAt is okay as long as the car is on warrantee but not good for my wallet when there is info more warrantee. I Hope with your charger that I can take the battery up to my condo and resurrect the battery after I start to drive again.

    I will be pushing MB to come up with a solution but your charger looks like a good fall back position. I am glad I saw this article.

    1. Paul – Thanks for your feedback. Yours is a great example of why a battery maintainers is recommended. The PL2320 would be great for the application you are mentioning, since it has the higher output, which may be needed to break down the sulfation in your battery. For ongoing battery maintaining, the PL2140 would be perfect. Thanks again, Jim from Clore Automotive

    Interesting, but what RESEARCH, using double-blind studies from an impartial source do you offer to back statement? I.e., the fact that you “believe” that trickle charging is not good for battery health over time, etc., is not good science. So, how about providing some good research that backs up your statement that there is a “better way.” Show it, and I will be inclined to buy your product; otherwise, I’ll save my money and/or look elsewhere.

    1. Neil – Thanks for adding to the discussion. We have over 70 years of organizational history in the charging game and millions of chargers in the field over that time. We have seen many limitations in trickle charging, particularly in light of the recent popularity of newer battery types. Our citing these limitations is based on our experience, field testing/reporting from real world charging situations and what our lab testing has shown, consistently over the last 10+ years. We respect that you may not find our stance compelling, but we will also say that, for many users, after switching to PRO-LOGIX, they wouldn’t use anything else. Thanks again, Jim From Clore Automotive

  4. Can you explain the specific charging requirements for a AGM battery.I have an R59 reproduction battery that spends it’s winters in a unheated garage on a battery maintainer.

    1. Robert – Thanks for your question. AGM batteries require specific charging phases (e.g., constant current bulk charging) and precise control of voltage. As an example, at 70˚F, a typical AGM should be charged to a voltage no greater than ~14.6V before moving into the absorption phase. Voltages higher than this can damage the battery’s internal structure. A charger designed to charge flooded batteries would typically charge a battery to a voltage much higher than 14.6V. PRO-LOGIX chargers feature automatic, multi-phase charging with temperature compensation to properly charge AGM and Spiral Wound batteries, as well as charge flooded batteries much more beneficially than an “old school” charger. I hope this is helpful. Thanks, Jim from Clore Automotive

  5. I don’t understand the different types of batteries or even know what battery types I have. I have a charger now that gives me the choice of AGM or “other”. How am I supposed to know what to use? My guess is that I am not alone in my ignorance.

    1. Woody – That’s a great question. Most AGM batteries today plaster the AGM moniker on the label, since they are quite a bit more expensive than an equivalent sized flooded battery. That said, if your battery is an original OE battery, it can be difficult to identify if it is an AGM. Sometimes, this information could be found in your owner’s manual, but sometimes is not. One quick way to know is if your battery has caps that allow you to add distilled water, it is definitely not an AGM, Spiral, Gel Cell or other newer battery type, as these batteries are completely sealed. Hope this helps. Thanks, Jim from Clore Automotive

  6. Would I need to push any buttons other than the on-off and not worry what type I’m hooking up to ? I have cars, trucks, boats motorcycles, atvs and 6 and 12 volt.

    1. Louie – Thanks for your question. Yes, you would need to identify your battery type with almost all of our chargers. Requiring this “choosing of the battery type” allows us to dial in exactly the power delivery needed by each specific battery. Using a “generic” charging approach may be good for some battery types, but will definitely not address the needs of the different battery types out there in today’s vehicles. Thanks, Jim from Clore Automotive

  7. I was also a little mislead at first about the intention or purpose of this advert-article. But it’s just business as usual and certainly no big deal.

    I do use a deep cycle AGM battery in my 2002 Pontiac Grand Prix GTP daily driver. I believe the AGM design offers several advantages compared to the less expensive conventional batteries.

    The battery was part of a charging/starting system upgrade. I enjoy feeling and hearing low frequencies while driving and the factory Bose audio system would be adequate for many but it politely refused to deliver the results that I was after. The same goes for the OEM Delco alternator which is rated for around 100 amperes. After installing the JL Audio component speakers for the front and rear channels, I chose two JL 10W6v3-D4,10” subwoofers in a custom sealed AV Priority enclosure for the desired low frequency response.

    A classic “Memphis Belle” 5 channel amplifier requires a lot of current to deliver the power required by the 1ohm subwoofer load. A generator/alternator designed for the reliability of a daily driver with adequate power to efficiently drive all accessories was needed. A heavy duty Mechman 240 amp alternator fit perfectly in place of the original Delphi. But the time has come to retire the Big Belle for something more efficient with a little more power.

    The OEM cables used for the charging system were more like wires because they were only 8 AWG. In my opinion that’s too small to efficiently carry the load requirements of the standard electrical components in the car. All under hood wiring related to charging/starting needed an upgrade. I used a Mechman “Big 3” cable upgrade kit. It uses massive 1/0 AWG cables made with thousands of strands of pure Oxygen Free Copper (OFC) covered in a thick but flexible heat and abrasion resistant color coded PVC jacket. The kit includes brass ring terminals for the 1/0 cables, heat shrink tubing to seal up the terminal connections for a professional look and a sealed fuse holder with plated connections.

    Some folks may think this cable upgrade is overkill but after making before and after voltage tests, it’s easy to see the benefits. The most common location for installing amplifiers is in the trunk area. The longest power cable is the amplifier positive from the normal battery location under the hood to the amp mounted in the trunk. The power cables that I installed previously for the first amplifier upgrade 16 years ago were 4 AWG which were fine for the small 500 watt amplifier

    Electronics and technology are evolving faster than ever and amplifiers are available that produce decent sound quality at insane power levels. More never seems to be enough. I did a number of different before and after tests when I upgraded from 4 AWG to 1/0 AWG for the battery to trunk mounted amplifier power cable. It picked up a solid 2.7 VDC at the amplifier which can make a noticeable difference in sound quality at higher current demands. Larger primary cables also reduce resistance which in turn increases efficiency and lowers the operating temperature of alternators and amplifiers.

    I guess I said all of that so I could say this….my battery charger is a really good “old school” type with all the bells and whistles available a couple of decades ago. It works as intended but if there’s a better one in my future I would like to know more about it.

    1. Daniel – Thanks for adding to the discussion. We are with you that your upgraded cables aren’t overkill, as evidenced by the massive voltage improvement you saw at the amplifier, which not only improves your sound but also reduces the stress experienced by your amp. All electronics do better when they get the power they desire. With regard to your older charger and your AGM deep cycle battery, if what you are doing works, that’s great. If you wonder if it is suitable/optimal for your battery, connect a voltmeter to your battery posts 2-3 minutes after starting a charge routine when your battery was well discharge prior to charging. If you see voltage north of 15v, it should cause for concern (unless it is really cold out). It is being overcharged. Thanks, Jim from Clore Automotive

  8. excellent article. for the ones complaining about advertising, this is not strictly ads. yes, it is promoting one brand, but reasons or information is given to back this up. if you can’t be bothered to learn new things(exercise your brain)you are wasting a valuable resource, and are lazy! now, the main reason I am replying, is that I have a question which it seems you people might be in a position to know the answer. I have heard for many years, that it is not wise toave a battery sitting on the ground. they should be on a shelf or something else to raise them. I have never seen any difference. is this an old wives tale? any truth at all to this?

    1. Larry – Thanks for joining the discussion. I just revisited this topic earlier this week. The consensus opinion seems to be that, way back when, the rigid plastic battery case was porous and could allow current to leak out of the battery over time. This resulted in the admonition not to leave batteries on concrete. This is no longer the case and storing a battery on concrete should not cause any issue. Does anyone else have insight on this question? We’d love to hear from you. Thanks, Jim from Clore Automotive

  9. In regards to to the topic of a battery discharging if left on a concrete floor. I read an article somewhere that dates back to early batteries housed in wooden cases (probably the Model T era?). If left on a concrete floor, the wooden case would absorb moisture which in turn is a conductor allowing current flow, thus a discharge. With the invention of composite battery cases, especially the sealed units, this issue is no longer the case. Hope this information helps this issue.

    1. I read an article somewhere that said batteries would not discharge if left on a concrete floor and that story was most likely started so people wouldn’t leave batteries sitting on the floor where you could trip over them. LOL.

  10. I’ve been with Hemings for many years.Back when Hemings was a small news paper the. Went back to a Hemings car show, and it was worth the trip from Washington state.Keep up the good work—You guys are great. Glenn Hastings-Spanaway,Wa.

  11. Have used trickle chargers on collector cars for decades. Batteries and chargers last for many years. Learned long ago “if it ain’t broke….don’t fix it”. “Keep It Simple Stupid”. These mottos have saved me a bunch of money, time and frustration.

    1. Dave – Thanks for adding to the discussion. We are glad it has worked for you and respect your opinion and experience. Thanks again, Jim from Clore Automotive

  12. Check out Deltran Battery Tender. We have over 30 of them and some are over 20 years old.
    They work great at monitoring and maintaining batteries.

    1. Bruce – Glad that it’s worked well for you. Give PRO-LOGIX a try. We’d bet that you’d have a great experience with our products. Thanks, Jim from Clore Automotive

  13. Thanks for all the good information. Even though this is a paid ad it is very accurate and I wish I had information like this and the products in years gone past. I run and operate a heavy equipment construction company and am a boat and old car hobbyist. My most recent bad battery experience was in a man lift that required over $3000 in batteries because the factory charger went bad and my mechanic hooked a standard charger to it without proper knowledge and ruined the batteries. It’s nice to be able to take advantage of a product and support that takes some of the guesswork out of a seemingly simple task.

    1. Lou – Thanks for your comments. Sorry you had a battery experience. Yes, it is more important than ever to make sure that your charger is properly mated to your batteries. With boats and old cars, I am sure your total battery investment is quite high. Our customers have found that PRO-LOGIX usage can extend their battery life significantly. Thanks again, Jim from Clore Automotive
