Battery troubleshooting help, please?
This regards one of my elderly 90aH gel cells in my shave ice machine. Though old, they have been performing awesomely. Possibly until now? There are 2 12v batteries running a 24v motor. I'll ca...

Well, now, based on this morning's numbers, I am wondering if I do not have a battery problem but instead have a charger problem, or an electrical drain problem.
Normally I would test one charger against another, but I am down to one right now. Maybe I can fix another.
Battery A reads 12.6 at rest (that's the one that went down to half an amp draw suspiciously quickly last night), and battery B is 12.83. (I did not check its final amp draw; I just charged it till I went to bed. After the fire I am afraid to plug in overnight.)
12.6 is about where A was before charging, last night. So... why did it not draw the amps?
12.83 seems reasonable for B given that it was not done charging.
Landy's discussion of charger output voltage is relevant. I don't pay a lot of attention to mine, bec it is not adjustable. But his post made me realise i never see numbers starting with 14. I checked just now, and it is putting out 13.40. That's don't seem right. Yeah, looking up the specs, it is supposed to be 14.4.
I think my next steps are to borrow my neighbor's Fluke to confirm output voltage, and borrow or fix another charger to see what it does. Unless y'all have better ideas?
