I have a 2007 Road King. I'm still using the same battery it was manufactured with. I didn't place a battery tender on it until 2 years after I purchased the bike. The tender is only connected once in awhile. I've had my mechanic test the battery and he said the numbers are all good. Even though it's starting, can I still be doing damage to the ECM, starter, regulator or some other electrical component on the bike since the battery is so old?
