battery life???

I've heard that if you let your battery discharge in your motorcycle it is ruined. I have also heard that it's fine. Anyone know for sure? And why?

most people do not know about the little batteries and try to charge them like a car battery.....go to cyclegear and buy a 2amp trickle charger...thats all you need.

It really depends on the battery. Some will be OK, others will be ruined.

That's why you have heard mixed opinions. The only thing you can do is, like PowerSurgeD suggested, get a motorcycle specific charger and see what happens.
I have 3 Battery Tenders and haven't had to replace a battery yet (one is 8 years old). With a Battery Tender the battery is maintained at peak charge, which prevents sulfation. It's often sulfation that kills a battery because it builds up on the plates inside and eventually touches the next plate and causes a short.

Also, on non-sealed batteries you need to make sure that you keep the water level at the correct height (distilled water only). If you let the water evaporate out and then throw it on the charger you will burn the metal plates inside the battery and kill it.

i have seen them be ruined after a complete discharge many times, and have seen them come back without a problem many times. never bothered to take the time to find out why, specially since i was working at a bike/powersports dealer and we usually had 10-30 batteries on a 1.8 amp charger at a time. all we did was top off acid in the non sealed batteries, and then try to charge them along with the sealed ones. then load test and either use or recommend replacement.
