Simple way to ferret out a failing battery
Due to the 300 bucks per battery and having 12 to monitor between the two cars I didn't replace them until necessary
And contrary to all the battery experts I often replaced one and the rest of the bank went on to perform for several years
Currently the 4 T105 AGM's are on their second year and performance is significantly better than flooded albeit at a price

Were those in series or parallel? Series is the best way of course . Real easy to check especially under load. In parallel the only way to really check is with a hydrometer (on a wet cell- old school but will clearly find a weak cell)
