I recently acquired a
boat with a Promariner Prosport 12
charger connected to a starter
battery and 2 house
batteries - all wet cells. When I bought the
boat the house
batteries where dry - I added over a gallon of
water to both. Of course, they are dead.
I will be replacing them this weekend, but was wondering if the batteries died from neglect, or did they boil over due to the
charger? The boat was left on the charger for months while at
dock. Supposedly, this is ok - the charger is suppose to be able to turn itself on/off as needed.
Is there a test I can do to make sure the charger is working properly so I don't kill my new batteries?
