Well after two years the stock battery may have died. The reason I say may have is that I haven't ridden since August due to broken wrist. Anyways I started the bike almost every week and let idle for a few minutes, sometimes taking a short putt down the street. So should I replace the stock battery on my 07 WR 450 or just take it on a good ride and see if the battery will charge? I have no way of checking the voltage on the battery and it fires up on the second or third kick so that's not a problem. If I do replace the battery wondering what kind to get? Aftermarket for sure! Do not want to pay the $$$$ for a stock battery! Has anyone tried the E-batteries? Suppose to be lighter than stock, but do they charge of off the bike or do you need a battery tender? Thanks for the help!!
