Revisiting the ABCs of AGM Batteries


We have written about AGM batteries on several occasions in the past. In those instances, we have presented the case for why AGM batteries are becoming more popular, the specific requirements related to diagnosing and servicing them, and suggested that service facilities invest in the proper equipment to properly handle them. This time, we are turning it over to the magazines to reinforce the message that AGMs are here to stay and why it makes sense to understand their needs and tool up to service them.

Gary Goms Takes Us to School

In this great article from Underhood Service, Gary Goms covers all of the key points related to AGM batteries in a quick, concise read. He lays out the case for why battery testing is more relevant than in years past, reviews what makes AGM different from traditional flooded designs and addresses their unique challenges and requirements, both within the framework of the vehicle’s charging system and as it relates to charging them with external battery chargers. If you didn’t catch this one last month, it is really worth a read.


AGM Batteries – A Quick Primer

old_battery Another from Underhood Service and a great complement to the above article, this article breaks down the trends in vehicle technology that are making AGM the battery of choice. It also provides an overview of how the AGM battery interacts with the system and why that interaction is best managed using AGM battery technology.


AGM Batteries – What Does a Shop Need to Know?

AGM_battery This one is actually a repeat, but it does such a great job, we didn’t want you to miss it. In this article, Ann Neal from Modern Tire Dealer provides an overview of the service issues related to AGM batteries. She starts with a look at what is driving the increased use of AGM batteries as OE-chosen components and then jumps right into the implications of AGMs for shops, including a section called “Preparing for AGM.” It is a solid look at this changing area and a great complement to the above article.


AGM Batteries – When Do They Make Sense for Your Application

truckWhile this article is a little older
(2013), it has a great deal of useful information related to AGM batteries and where, from an application standpoint, they make sense to consider as an alternative to traditional flooded acid options. Specifically, Gale Kimbrough (the author) of Interstate Batteries, addresses AGM as an option for fleets, though what he has to say is relevant to the use of AGMs in a wide variety of applications. The one area where we might quibble with him is regarding the use of wheel chargers, where he says using a traditional wheel charger on a low setting is probably OK. We would disagree – only an AGM capable charger, such as our PRO-LOGIX series, should be used on AGM batteries. Otherwise, this is a great article from the point of view of someone considering the benefits of AGM technology.


When it Comes to AGM Charging – We’ve Got You Covered!

PL2410_action4Our PRO-LOGIX battery chargers have many benefits for shops, technicians, fleet service facilities and consumers alike, but one key benefit is that PRO-LOGIX chargers properly charge all lead acid battery types, including AGMs. That includes traditional AGMs, Spiral Wound batteries, Start-Stop AGMs and what Gale, in the above article, calls Dual Stage AGMs (pure lead AGM technology).



In addition, PRO-LOGIX chargers deliver automatic operation, temperature compensation (most models) for exact charging accuracy, enhanced maintenance mode (most models) for optimal long term charging, reverse polarity protection, special Soft Start and Recondition modes to properly handle problem batteries, and the convenience of a forced start mode that allows the charger to activate when connected to a completely discharged battery. That’s why we they’re “Not Just Smart – Intelligent.”
