Hey guys, I left my ignition on for three weeks while out of town working. I came home and was ready to ride. I pulled the bike out of the garage and realized my error. I checked the battery with a meter, it didn't register at all. I put my trickle charger on and checked it this morning. It is only reading 4.4, I think the battery is toast. Anybody know if this battery will come back to life or am I heading the store to purchase another battery?
