    Cloudsurfer –

    I bought this to replace the battery in a utility jump-starter, air compressor piece of equipment which is rarely used. I only know that it fits exactly as advertised and seems to be working great. If I’m lucky I’ll never actually depend on this thing helping me with my car, and will never have to learn about its longevity.

Easy installation of mighty max battery
Jim Shutes
Both batteries arrived a little late, but good to get. Packed nicely. Easy installation in a Schwinn S180 scooter.
Bob Widders
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!
Baltazar Martinez
Arrived well packed as described, no damage, easy instructions & also easy to register for warranty.
