Before I pulled my boat out of the water, I tried starting it and got nothing. My practice was to leave the battery charger on thinking it had a maintenence function similar to a Battery Tender. The company that winterized the boat said I cooked both batteries....2 1 year old Interstate Megatrons.....did I just learn an expensive lesson? How can I check to see if the batteries are still good? The boat is a 1999 Monterey 262.
Thanks in advance!
