I was given some 155ah marathon agm batteries that are about 5 years old. I tested them by fully charging them one at a time and running a 50 watt air pump until my inverter started beeping.
One battery measured 150ah, one 75ah one 100ah, three at 50ah, one at 20ah and one at 10ah.
I will throw out the worst two.
Are the 50s worth connecting to the bank or will they do more harm than good?
I'm just looking to squeeze another year or two out of them before a buy new batteries.
