Paul, It is not so simple. As David suggests, it is best to read Lee Hart's battery charging basics: http://www.evdl.org/pages/hartcharge.html
There is a _lot_ more to charging batteries than you might think. Even Lee's "brief" tutorial leaves quite a few of the subtleties out.

Lead acid cell voltage is 2.15 volts. 6 cells make 12.9 volts. Anything above 12.9 will charge it fully. Sent from my Verizon Wireless 4G LTE smartphone-------- Original message --------From: Robert Bruninga via EV <[email protected]> Date: 1/12/2016 9:07 AM (GMT-06:00) To: Electric Vehicle Discussion List <[email protected]> Subject: [EVDL] Lead battery charging to 13.2v I put a gel cell on a benchtop power supply and it charged overnight to zero current at about 13.2v. So I upped it to 13.8 to finish the charge and it basically would not take cany more current. I always thought the 13.8 and even 14v was the float voltage and you had to at least get to that voltage. I also remember that something like 13.2 is the highest one should go to provent any gassing Anyway, if one leaves a battery overnight on 13.2v and it tapers to 0, is it âfullâ. If so, what is 13.8 all aboiut. Bob -------------- next part -------------- An HTML attachment was scrubbed...
