Battery charging

Postby hap2 » Sun Jul 13, 2014 10:42 am



When I tried to start the bike after my buddy changed the oil today, it wudn't start. He put a charger on it & it started. It's not the alternator bcuz the lights increase in brightness when I rev it up. It got enuf charge in it to start but once I got home (10 min ride), when I shut it off, it wudn't start. I took the battery out & it's been charging from a 2 AMP charger for the last 13 hrs. How much longer shud I leave it on? (I DO have a battery tester, but not a multimeter)

Thanks again ( I REALLY need & appreciate your help & wisdom)

UPDATE:

I just put the load tester on the batter & without giving it a load test, it showed 12 V. (just hooked up).

When I gave it a load test for 10 secs, it shows just under 10 V. IF the battery is good, why wud it die? Would just riding around town in 10 min spurts do that? It DOES have a bunch of lights on it that aren't stock, but still. Wudn't it charge anyway, or wud I have to give it a good highway spin for 20 min or so to fully charge it up?

GL1500's need LOTS of power. They will not run reliably with a battery that is even a bit weak. If your battery is not holding a charge consistently, as it sounds like yours is not, it's time for a new one.

I agree that it appears your battery is cooked. Have you checked the electrolyte level(s) in the cells (if it is a wet cell battery)? If the levels are LOW, you can TRY adding some de-ionized or distilled water and then putting it back on the charger for a slow recharge... BUT, it is probably fried.

I copied this off a Battery web site:
All Lead acid batteries (Gel, AGM, Flooded, Drycell, etc) are made up of a series of 2.2 volt cells that are bridged together in series to reach their final desired voltage. For instance, a 6 volt battery will have 3 cells (3 x2.2= 6.6 volts), a 12 volt battery will have 6 cells (6 x2.2=13.2 volts) and so on.That 2.2 volts is the fully charged, straight off the charger number. The actual resting voltage, or the voltage a battery will settle at 12-24 hours after being removed from the charger, is closer to 2.1 volts per cell, or about 6.4 volts for a 6v battery, and 12.7 volts for a 12v battery. These numbers assume 100% healthy cells, and may vary a bit lower for older batteries.

Lots of good information there, if interested.
I am wrong as often as I am right concerning what is wrong with someone else' motorcycle without having seen the machine in person. Guessing with limited information, as to the source of the trouble, is sketchy at best.

Thanx alot for the reply & info, but under a load for 10 secs with a load tester, it showed just under 11V & that was after a 13 hr charge with a 2 amp charger.
