    Just got it. Worked as a charm. Didn’t wanna install first day so I thru it on my charger. Just because. Bike started right up. Just rode around the block once. No complaints so far. 2005 gsxr 750… After about 2 months… I like like it… Only thing I hate is screwing in the positive n negative screws… Well if you have big hands… Lol

    Just installed it a couple of weeks ago. Let’s see how long it last with a trickle charger through the winter months.

Great product. Fits my 2003 Yamaha Big Bear 4x4 400 quads. No issues.
Identical battery, perfect
THE ITEM ARRIVED AS I WAS TOLD, VERY WELL PACKAGED IN A STURDY LITTLE BOX, YOU GUYS ROCK
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.
