I'm the 3d or 4th owner of an '82 E-25+ that I can only guess has the original electrical system (or most of it) in it. I currently use two Group 24 Dual Purpose lead-acid batteries to start the Yanmar 1GM diesel and to run the cabin and running lights. (I always start with battery 1 and only use battery 2 as the house battery-- until I have to switch to "Both" to get the engine going which is where I am again today.) I've gotten 3 years out of my most recent pair. However I've been thinking about making the move from the flooded batteries to the newer AGM type. But I've read in various magazines that altho in many cases the recharging system for the lead batteries works well with the AGM batteries, in some cases it does not. The gal at West today told me the newer rechargers even have separate setting for lead, mat and gel. Has anyone had any experience with swapping over using the OEM charging equipment? Should I just keep going with the lead-acid batteries and play it safe? Thanks for any input.
