Partially damaged battery?

Recently my alternator's "sensing" input became unplugged yielding what I expect to be a constant 16v output..whoops. When I recently spent 5 hours motoring back (due to storm damage to my sails) I got that sulpher smell that indicates one is cooking their battery -when it rains it pours. So I turned off the engine to let everything cool down. Is it safe to keep using this battery? Currently it holds a charge (12.6 ish after charger is off). However, my 3 stage charger never switches from the "absorb" to the "float" stage.

Re: Partially damaged battery?

Since we're not there on your boat with you, only YOU can figure out the condition of the batteries. Check the case, check the water levels, disconnect the charger(s), let it sit for at least 24 hours and use a hydrometer. Most likely toast, although if there's still proper water levels, just consider it an equalization! Good luck.
