Simple battery question.

Post by fcanary » Wed Aug 10, 2016 9:10 am



While out riding the other day, I stopped for gas. All the pumps were full so I had to wait a minute or so. Finally a pump opened up, and I started forward, and stalled the bike. Duh, mind was elsewhere and I didn't realize I was still in 2nd gear. Went to start it and it lugged, like the battery was almost dead. It did start up as normal once I filled up. Got home, pulled the battery, checked the stator connection, which looked good, but I still need to solder it. I popped off all the caps and the water level on three cells, on the positive side were way down, and the other three were down, but just a bit. I filled them, cleaned the connections and reinstalled the battery. I think this was my problem, but I need to get my meter (on vacation and it's at work) so I can check the output of the stator. After being long winded, my question is why would the battery run almost dry in three cells? It isn't cracked, and no signs of leaking, either around the battery box or the vent tube. It came with the bike when I bought it two years ago. I don't mind buying a new battery, but would rather wait until next season. Any thoughts?

Hopefully you didn't use tap water is my first thought. Yeah low electrolyte will make your battery do this. Next one, get an AGM and not worry about it. But if you used tap water, your new battery is closer than you think.

Hot days and high charging ( maybe 15+) can boil the battery dry. i would check it couple times a month for electrolyte. (water)

Ditto above for wet cell battery. Double check charging rate to see if in spec. Went to AGM style battery also, they hold up better.

Thanks for the info, guys. I go back to work Monday and I'll grab my electricial meter and check the charging rate. Hopefully it'll last until next season, then I'll put in an AGM battery.

Best deal I've found on Odyssey AGM battery. Just bought two this past Spring, one for GL1500 trike, one for '85 1200. Last one in trike lasted in trike was put in in August 2004, removed Spring 2016 still cranking. It's now a portable power supply for small testing and I will carry it in a pouch when on my '74 Triumph.
