Re: Trolling motor batteries
Do yourself a big favor and select a battery which has at least twice the capacity you expect to ever need. This way you should seldom if ever drain it to the point of damaging it. No battery, not even a deep cycle, can be fully drained without causing permanent damage. You can do it a few times, but the battery will have a drastically shorter lifespan. About half way drained will have little practical effect, however. More smaller batteries will generally be more expensive than one somewhat larger battery.<br /><br />A good friend uses a trolling motor on his canoe. He uses either an Optima or Orbital I think. They are spillproof AGM batteries, and I suspect are lighter for a given capacity. While not cheap, they would do a nice job. Besides, you never know when a wind or current might kick up making you wish you had more battery to fight your way home.
