Sorry in advance for being long-winded... Bought my first boat last year and have a dumb question about the battery and charging it. I bought a new Interstate Deep Cycle trolling battery to replace the old one that came with the bass tracker I bought last year. (Interstate guy agreed it was shot.) I also just bought a new Craftsman automatic battery charger with a 2/10/50 amp switch and auto shutoff. I hooked up the charger last night per the directions and set the charger to 10 amps and set the switch to deep cycle - not conventional. The book estimated that a deep cycle battery with reserve capacity of 180 would take about 6-7 hours if it was dead. My battery has a reserve capacity of 210 and I left it on the charger for about 6 hours last night, but could never get it below 6 amps on the charger. (I believe when the charger is only charging at 2 amps that is when it shuts itself off.) The plates were bubbling pretty well (caps off of course) and the battery was pretty warm, but not hot. I'm worried about overcharging and possibly harming my new battery. How long are you guys charging your trolling batteries and what settings are you using on your charger. Also, if you're using an automatic charger do you trust it to shut itself off? Just trying to get some good advice before I learn the hard way, thanks.
