Good Day All. Reading the thread on AGMs and discovering that 'mini charges' (with solar panels etc) will degrade them is bad news, and also that equalization is sometimes necessary makes it worse. The reason I use them is because maintaining acid batteries is a bore. I had gels before and had good results with them, but AGMs came along, I thought all my problems were over. I thought that my 80 watts of solar power was well enough to top up a pair of 8Ds (and two G27s for the diesel) but if not going to full charge is not good?! That wasn’t in the advertizing! I upped the alternator to 200 amps; installed a Balmar Max Charge and a PV7D regulator for the solar panels and battery combiners, all on the quote from West Marine that ‘batteries don’t die, they’re murdered’. So now I’m guilty of involuntary man slaughter. Usually the batteries are all showing at least 13.2 volts when I go aboard, now it’s 12.8. I will do a ‘full charge’ with the engine and see what happens; wish me luck.
