There are things you can do to maximize life of the cells and the manufactures have recommended voltage and current settings but they will charge all the way up with anything above 2.15 volts. I prefer to go to manufactures recommendations myself. http://www.trojanbattery.com/tech-support/battery-maintenance/

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. Bill D. At 10:37 AM 1/12/2016, you wrote: >Lead acid cell voltage is 2.15 volts. 6 cells >make 12.9 volts.
