Batteries Specifically Designed for Jump Starting


Occasionally, we are asked what we mean when we say that the batteries used in Booster PAC and Jump-N-Carry jump starters are specifically designed for vehicle jump starting. The answer to this question is the most critical element of why our jump starters are powerful, reliable and durable.

Many jump starters utilize batteries originally designed for the backup power / power supply industry. These batteries are designed to provide a relatively low amount of power over an extended period of time, such as when the AC power to a building or cell tower is interrupted and critical systems must be kept powered until AC supply resumes. So, low power over a long period of time is what they are specifically designed to deliver. As a result, they are ill suited for jump starting, since the jump starting application requires a relatively large burst of power over a very short (< 3 sec) period of time.

This has numerous implications for the design and construction of the battery. For instance, the intercell connections that join the various cells together to form a single battery must be robust enough to pass that high current through without excessive heat or damage to the battery itself. Other important enhancements include a thinner plate design so we can pack more plates into the battery for greater power, a high lead purity level in the plate for increased power and longer shelf life and enhanced chemistry to support the greater power potential of the battery.


When it comes to the starting power and durability of a jump starter, the most critical component driving that performance is the battery inside. Our ES Series, Clore PROFORMER and X-Force batteries are specifically designed for use in vehicle jump starting applications – they provide extremely high power output, extended cranking power and a long service life. That’s why they can stand up to years of day-in, day-out professional use.

Bet on the Battery – It Makes All the Difference

    1. Paul – Thanks for your question. I suggest calling our Tech Service line at 800 328 2921, option #2. Thanks again, Jim from Clore Automotive

  1. With technology changing,I think it’s time for a new battery part # ES1217 , just wondering if worth the while to buy a replacement or a new unit

    1. Ramiro – Thanks for your comment. We have upgraded the replacement battery for the ES2500 to the ES1230 battery. It is quite powerful (it is the ES5000 battery). It can be worthwhile to replace the battery after the warranty period is over, assuming the rest of the unit is still in good condition. Thanks, Jim from Clore Automotive

    1. Ahmad – Thanks for your question. The ES5000 does not get a serial number but does get a production batch code. You should see it along the side of the unit, below the clamp. It would look like this: 25JUL23. Thanks, Jim from Clore Automotive

  2. I have a model ES400, the only thing with it is the connecting wires to jump the battery, is there a charging cable or power cord available, it belongs to a friend and she can’t find any wires or plugs for it.

    1. Barbara – Thanks for your question. Yes, it has a dedicated charger. The charger is Model ESA275. Only the dedicated charger should be used to charge the unit, which is true of all lithium jump starters. It can be purchased on our website ( or via phone at 800 328 2921, option #1. Thank you, Jim from Clore Automotive

  3. My booster pac battery is a es2500 1100 peak amps. Battery replacement #ES1217. All pictures of batteries shows spade type terminals. Mine has screw stud terminals that stick out of battery like posts. Connections screw onto studs. What battery has this type of mount? Bought jump pack 11/2019. Don’t use much. Private use only.

    1. Tom – We apologize. The battery kit photos are old and out of date. Current battery kits include batteries with the stud style terminals. Thanks, Jim from Clore Automotive

  4. I have an X-Force Model JNCXF battery charger, and am looking to replace the battery. Not sure which one to purhase. Please advise. I know this is an older model and want to ensure that I am purchasing the correct one.
    Thank you

    1. Donna – Thanks for your question. We no longer manufacture the X-Force battery, but the JNC105 is the appropriate replacement battery for you JNCXF unit. Thanks, Jim from Clore Automotive

    1. David, Your best bet is to call our Customer service team at 800 328 2921, option #1. They will be happy to help. Thanks, Jason from Clore Automotive
