Re: Trolling Motor Batteries
I usually recommend that people buy the largest capacity they have room for. You cannot buy too much power -- just too little. Capacity on deep cycle batteries is shown on the label as "Reserve Minutes: xxx @ 23 amps". The larger the xxx number is the longer the motor will run. The 23 amps is simply the measurement point and will generally be constant among the battery manufacturers. I would think you want either two group 27 or 31 batteries. 31's are heavy and a little more pricey. As for where to get them, I buy mine at our local farm store (called Fleet Farm). The work fine and are much less expensive than buying them at a sporting goods store. There are other farm stores around the country so if you live in a very large city, you may need to check some smaller cities in your area for farm stores.
