I left my ignition on overnight. Battery was completely depleted in the morning. Of course bike does not start. I took out my charger and charged my battery until I have an ok light from the charger. Bike started right away after charging for good amount of hours.


My question is: Now that my battery has a history of being drained, is my battery will give me problem in the future? Should I go ahead and buy a new one? Thanks. Battery is a year old.

 

That probably didn't do the battery any good but I would not consider it ruined. If it were me, I'd leave it alone. Just keep it on the charger when it's going to sit in the garage for an extended period.

But that's me. I'm sure there will be other opinions following.

 

I don't know everything about these new bikes but if it were me I'd probably be more concerned about any possible damage to my coil and other ignition components from over heating. Check the coil for any signs of swelling, cracks or leaks. When the bike is running pay attention for any skipping or missing when things get up to operating temp.

 

It is all ruined.Buy a new bike.

 

I have 15 year old boat batteries that have been drained completely and still work fine. But I have had others that never held a charge again. I would put it on a battery tender and check your voltage. Most of my batteries charge up to 13.25 volts. If they won't charge past 12.75 they should be tested by a parts store.
Good luck. One reason I always use my fork lock is to make sure I shut ignition off.

 

I did the same thing on my 2013 Road Glide. (battery only read 3v) It took several tries with the battery charger to finally get it to take a charge, but eventually it did. I rode it for another year with that battery and had no problems. I then traded the bike in. After the incident I kept a battery minder on it whenever I was not riding it.

 

Another reason why I do not use the kill switch.

 

Exactly^^^ Although one time I accidentally hit the kill switch getting off. When I got back on to start it up I cranked a few times and nothing. I thought oh crap!! Then I looked at the kill switch lol.

 

It is a fact that letting a battery drain completely does shorten its life, but 1 time i'm sure it will last a good while yet.Standing voltage on a battery is important but its not the only test that should be check.A load test should also be checked.In alot of cases an older battery will maintain a decent sitting voltage( for awhile anyway) but will fail a load test.Cold cranking amps are the soul of a lead acid battery.

 

Bad *** lookin' awesome dobies ya got there too Hawq295.
We have two miniature pinchers that we just love to death.
The min pins and the dobies have no blood in common but they do look like little versions of dobies.
