To tell the truth I didn't take care of that batterie very good at all.Dropped down a 50-75 foot hill a couple of times,submerged it, never charged it all winter, pulled it out in spring and set my automatic canadian tire charger to gell setting on 2 amps and away we go!!! The Cyclone motor is a 24 volt motor running threw the 7 gears. Hence two 12 volts.
