Hi Tom,These are Trojan L-16E batteries, 370 AH. They have a 2 hour absorb cycle at around 29.3 V. There is one series string of 4 batteries in a small, off grid cabin that is used 3 or 4 days a week. The system has 980 Watts of PV with an Outback FM 60 CC and an Outback 3524 VFX inverter.
I was concerned to read that John and Bob have been seeing more problems with the Trojan L-16s lately. They have been a standby for this type of system. If they truly are not lasting as long as previously, what other options do we have for a reasonably priced, decent quality battery in that amp hour range?

What is the Bulk/Absorb voltage and time? Equally important is the design of the bank series or series/parallel and if parallel how many strings. Lastly which Trojan L-16 are these?Tom Duffy Senior Solar Design Engineer Real-logo-X-195 Toll Free 888-895-8179 <mailto:t...@thesolar.biz>t...@thesolar.biz Customer Service and Accounting 888-895-6810 Grid tie sales 888-895-7847 Off Grid sales 888-895-4058 Other Product Sales 888-895-9612 Central America Sales (Panama) 507-6-126-1253 Shipping and Receiving 888-895-6497 Tech Support 888-895-8179 SKYPE: thesolarbizFrom: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of DrakeSent: Monday, July 15, 2013 8:59 PM To: RE-wrenches Subject: [RE-wrenches] Trojan L-16s Hello Wrenches,A 1 1/2 year old bank of Trojan L-16s had a battery with a dead cell. I have heard that there have been some complaints about the L-16s lately. Has anyone had experiences with Trojan L-16s (or the RE series), good or bad? Are they still a good choice to use in off grid systems?Thanks, Drake Drake Chamberlin Athens Electric LLC OH License 44810 CO License 3773 NABCEP Certified Solar PV 740-448-7328 <http://athens-electric.com/>http://athens-electric.com/ _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Change email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.orgList-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.orgList rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
