    Please help me figure out the life of my new trolling motor battery. I wish to run a 12v electric trolling motor, which pulls 20 amps of current on full power. I just bought a 12v deep cycle lead/acid battery from NAPA, rated with a reserve capacity of 130 mins. Amp hours are not specified. The only other specs listed are cold cranking amps at 0F= 500. Cranking amps at 32F=625. Test Load Amps= 263 amps. How long will my battery last (best scenerio) for this trolling motor if run at full power? THANKS!

    Note that temperature will also have an effect on battery performance. Reserve Capacity is typically measured at around 27°C (80°F). That's the battery temperature, not the air temperature. A cold battery won't work as well, so fishing on those cold mornings might not last as long as fishing on those warm evenings.

    Of course, any fishing is good fishing!
