Hey guys
Have a question for anyone willing to answer.
So I grabbed a new 10L-b2 yuasa battery and the shop put the electrolyte into it and I let it cool down. Took a meter reading and got 11.78 ish.
I put it on my 2amp trickle charger (lowest I have but the info sheet says no more than 2amps charging) I let it charge but never got it completed (5-6 hours)before I didn't want to monitor it into the evening. (It's automatic, but still!)
I tested the battery in the morning and it had settled down to 12.25v. So I threw the charger on it again for another bunch of hours and it seems to not really be getting anywhere.
I know it's "working" as I can hear the battery bubbling, but after this long I would have expected it to be charged.
When I disconnect from the charger, it's sitting at about 13.2 but as it settles down it just falls below where I would expect it to be at this stage.
Anyone?
Beware voltages for AGM differ from acid refillable batteries.
Over 13v i would stop, no point on evaporating the electrolyte.
if you are using 2 amps use short charges, its always better to use a low amp for a long charge.
Let it sit and monitor it. above 13 should be good.
If you have something to put a load ( 2-3 amp, a bulb maybe) and measure the voltage drop and how it restores the voltage after disconnecting the load. It should go up again to almost the same voltage it had before.
If the bike starts easily you wont have problems. If you can turn off the headlight to start even better.
Thanks Armandorf
Yah, I had it off and put a small load on the battery. Started at 12.45 and dropped to 12.25 after a few seconds of the light on it. Never bounced back. 🤷
Have you checked with another voltmeter?
...no. :cookoo:
Ok, so you have no idea if your readings are accurate or not, fair enough
Over and out....
