They served me well and after 18 trouble free years I changed them to NAPPA 31 series GEL batteries. I considered changing to AMG's but was concerned with the Charles Charing charging profile.. see attached.... Soo far so good after 2 years... M2C
That’s the same profile I got from Charles for my chargers. Doesn’t seem compatible with AGM, but then I’m not an electrician. Wrenches don’t scare me, but I hate electrical work!

Any graphic, information, comment, etc that groups all 'AGM' batteries together is worth exactly zero.

So when you say “close” in terms of profile…what do you mean? How close is close enough to be good enough?

Mission complete, started to replace the parallel battery switch then the post broke off the engine battery switch so I replaced that one also. Hard to believe such a poorly made switch is at the heart of the entire electrical system. Anyway as soon as I hooked up the new cable and switches everything came back to life, i believe the charger came back on 2 days ago when I fixed the loose wire because they were fully charged and the engines fired right up on the engine bank only. Now I can excuse myself from the AGM battery conversation and get back to the 50 other things I need to fix
.Thanks again for your help Hiccup!!
