I have two batteries on my boat. #1 is a marine starting battery and #2 is a group 27 deep cycle. I showed up to the boat last night and noticed that my #1 only had 10.5 volts, I was like that can't be correct because I have a Guest Marine batterie charger installed. I turned on a few lights and sure enough volts dropped to 4 volts, "yep that battery is dead!!" But why wasn't the charger charging it? A quick examination with my hand held volt/amp meter said the charger was putting out 10amps at 10.5 volts on #1 and 12.8 volts at 1 amp on #2. I felt the side of #1 and it was extremely warm, and #2 was room temp. Also #1 fluid level is good and was bubbling and continued to bubble even after I disconnected it.
I disconected the charger from #1.
So the question is did my charger malfunction on #1 & kill my battery? Or did my battery short a cell and my battery charger is just trying to recover it?
I don't want to kill another battery if it's a bad charger, and if it is a bad charger is there any hope for saving this battery?
