    Mighty Max is a clear case of you get what you pay for, but in a good way. They are a budget battery, clearly. But, to be clear, they are the best budget battery I’ve found after a decade of owning ATVs and Snowmobiles. It is, again, however – a budget battery. Which means the posts are large and are a pain to get the nuts to align with the screws when connecting your +/- cables (especially in my case, when installing in a Polaris ACE150 where the battery is on the rear frame under the seat. Almost impossible without octopus arms and 8 fingers). And, speaking of posts, they are very fragile, so do NOT overtighten the nuts on the post or they will twist out of alignment – making for poor connection and premature battery failure. But, all that aside, once the battery is installed delicately, it will last you a good long time – not as long as some top-tier name brand batteries. But certainly longer than the no-name batteries that come stock in the Asian brand machines these days.

Great product. Fits my 2003 Yamaha Big Bear 4x4 400 quads. No issues.
Identical battery, perfect

Purchase a mightymax 12v battery for my 2015 S400 hybrid Mercedes on Ebay in June 2026
Ship it to jamaica, west indies
It works perfectly as a replacement auxiliary battery
Next test is durability
Thanks Mightymax
Easy installation of mighty max battery
Both batteries arrived a little late, but good to get. Packed nicely. Easy installation in a Schwinn S180 scooter.
It arrived in good time. Installed in my 2006 Seadoo gti-se 4tec PWC. I hope it lasts better than the last Voltz battery. Started getting weak after 2nd season. (2 years old) Wouldn’t start my PWC. The shell showed signs of cracking. Always kept in heated garage during off season & properly maintained with a charger. Time will tell. I was quite surprised that being a US company , that the battery is manufactured in VIETNAM!
Arrived well packed as described, no damage, easy instructions & also easy to register for warranty.
Works perfect and perfect fit. Great battery
Battery arrive n3xt day in perfect condition partially charged. Installed in my dewalt battery charger it was 15$ cheaper than the local store.
