    It doesn’t hold a charge very long

    Would have cost me over $150 to replace my jump pack. For $40 and 10 minute fix I have a working pack again.

    I have a number of Quick Lubes and keep ES2500 Booster Pacs at each one. I have purchased several of these replacement batteries and they fit and work fine even though the + and – posts are in a different spot. Make sure you take the jump box apart to get a visual on the original battery because some have external posts. Also the a/c charge adaptor could be faulty.

    Used this product in an old Napa Jumper Box for our shop.This batter was a replacement for the original battery, made by original manufacturer…this battery was about 1/3 of the cost for an original replacement, and it will start a truck with NO BATTERY In The Vehicle, let alone a vehicle with a low battery.SO GREAT PRODUCT FOR A GREAT PRICE !!!

Solid looking battery, came well packaged. Have used their battery before for my lawnmower and now looking forward to see how it lasts in my snowmobile.

Thanks Larry

So far these Might Max batteries are good but it’s only the first day and they were on charge for 12 hrs. I’ll have to come back and do an update at some point in time. Ordered them on Amazon and got them the next day. I was encouraged by Mighty Max to make this google review and post pictures to extend my warranty for 3 months but there is no way to post pictures 🤣🤣🤣 It’s been a few months and I was able to go back and edit, so here is a video I made, the rest of the photos I have deleted. Batteries are still going strong. Update 12-11-2025

They arrived within 2 days of ordering them packaging was really good I haven't put them in my MX350 yet I hit them with my multi meter fresh out of the box and got 12.4v on both batteries so that is good
