It works perfectly as a replacement auxiliary battery

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.
