I recently did some research to find the best replacement trolling motor battery for myself.

When getting a battery for your boat its good to take the following into consideration:
1.Must get a deep cycle marine battery (as opposed to starting battery or car battery for trolling motor).

2. R.C. minutes stands for reserve capacity minutes which is the time it takes to fully discharge a battery with a 25 amp draw. R.C. minutes can help you predict how long you can run a trolling motor off the battery. A good standard is a 40lb thrust trolling motor on full speed draws about 42 amps continuously.

3.Cranking Amps is the amps the battery can give out in a 30 second burst. Useful if using battery to start a gas powered motor.
Marine cranking amps and cold cranking amps measure the same thing (amps the battery can give out in a 30 second burst) just at different temperatures. Marine cranking amps is always about 1/3 higher than cold cranking as marine cranking amps are measured at 32 F while cold cranking amps are measured at 0 degrees F.

4. Determine how dependent you are on you battery if you should get a cheaper battery or more reliable and more expensive battery. Personally, since my gas motor pull start I found the cheaper deep cycle battery (got one at Sam’s Club for $85) was most economical.
