It's possible the battery could be bad. 4-wheeler batteries tend to go bad if they sit for a long time, but it should have lasted longer than that. If you have a voltmeter, check and see how many volts it's showing. Then, try charging it overnight on the lowest setting on your charger and see if it comes up any. If it doesn't and it's showing low voltage, then I would say your battery is definitely bad.Brought home my 09 recon this past December. I rode it a few times in the snow, but now, it won't start with the battery. I have to pull start it. I've checked the battery cables, they are clean and tight, and the battery is sealed. I've even tried to trickle charge it. Could the battery be junk already??? Any ideas??
