I hope I didn't mess up my 2 trolling batteries. I have been charging them with a portable battery charger from Walmart that charges at 2, 4 or 6 amps. It is suppose to quit charging them when they are full. The first two trips I got about 6 hours of life out of the Terrova with I-pilot... The last two trips I am only getting 2 hours of life. Guess it is time to either get a Minn Kota portable charger or an on board charger if I have room to mount it somewhere.... Any ideas what could have happened? Could the charger be charging them too long? Should I check the water in them or anything? Man I hope this don't cost me two new batteries....
