hi tom give us some information on the charge/discharge cycle the batteries will experiance.
For long life i like flooded batteries, and you can access the electrolite to determine SOC i like AGM over gel, but have little experiance with either. my experiance is the agm last longer than gel, and nither will last as long as flooded. i have 10 year flooded, and they are still working, and I CAN NOT remember sealed over 3 years ( AGM) Darryl, --- On Thu, 10/15/09, tom jacoby <jacoby_...@hotmail.com> wrote: > From: tom jacoby <jacoby_...@hotmail.com> > Subject: [RE-wrenches] Sealed Batteries > To: re-wrenches@lists.re-wrenches.org > Date: Thursday, October 15, 2009, 5:26 PM > > > > > > Hello, > SELF is considering new battery options for our off-grid > projects (primarily health centers in Africa at this > time).
