I'm on my 2nd.....I keep mine on a trickle charger/battery tender. Lots of guys that I respect on here love this batt but its the last one i will own. Just dont trust um 100%. Originally Shorai said the standard batt tender was fine but some guys on here say NO and if your running your big ktm with accesories the battery will not full charge while riding.
Cheers and good luck
