When AGM batteries die is it always suddenly?
remember the acid becomes more concentrated as you lose water.i get these types of battery often that are testing poorly but have an unusually high oc voltage at rest after being fully charged.i carefully add small amounts of water and let it soak in.then do an impedance test.if still poor i give each cell another dose of water.if its still not improving its just worn
