SD, I have three banks----house, engine starting, and generator starting all are AGMs. I have two 80 amp alternators charging through a combiner. According to my battery monitor about 100-120 amps is the max they will put into the house bank. That's about a 20-23% of capacity charge rate. That seems to do the job.

Baker, About 4 years old. Since the "ladies" have lied to me before, I have no idea how long they stayed flat. Maybe 4-5 weeks. At least the combiner protected my other banks.

Art, I use AGMs for several reasons. One is I am not there to tend them all the time. Two the house bank resides under my generator. It would be difficult to slide them out for servicing. Three I can charge them faster without worrying.

Edit: Baker, the Lifelines had a 5 year prorated warranty. That would be against list price which would still make them about $800.00. I thought the Dekas were the best deal at $485.00 ea.
