Just curious.

Anyone using AGM batteries in their 32 volt system? At the start of this season we wound up with three bad 8 volt batteries (Deka 819), mostly due to the LaMarche "battery cooker" and decided to replace both the charger which was original to the boat and and all the batteries since they were at least three years old.

Couldn't get Deka 8 volt batteries of any kind as three different sources told me that the manufacturer was out of stock and not likely to have any available until later this year and Rolls was telling me at least a couple of weeks for delivery. Wound up going with Full River 8 volt AGM batteries marginally greater than the 819's in AH & CCA.

So far the combination of a new Analytic Systems charger and the AGM batteries seems to be working very well. Replaced the old, rotted fiberglass battery boxes with new NOCO units and the generator room cleaned up beautifully.

Now I'm wondering what I can anticipate for life expectancy for these AGM batteries in this application.
