After being charged for about 1-hour, the AGM battery should feel slightly warm/hot when you touch. While the charger getting warm when charging is considered okay, excessive heat indicates battery faults. You must immediately discontinue charging when the battery feels hot if you touch.
Can a charger detect a faulty battery?
The charger cannot detect it is not faulty but that the minimum voltage may have merely slid below the charger threshold. So, the charger cannot understand the ways to treat the battery to turn it on, so it selects doing nothing. The low internal resistance in AGM batteries allows output at a very high amperage for the battery to power accessories ...
Can AGM batteries fail?
Batteries, generally, including AGM batteries can fail in time. Many cases consider these batteries to be dead where they are deeply discharged. Here lies a problem with most battery charging devices that they come with built-in features of safety that prevent recharging faulty batteries although they just may be deeply discharged.
