How to Care For Your Trolling Motor Battery – Step by Step Guide
Even the best of battery won’t perform to its specifications if it is not properly cared for. Here are some tips to help your battery last as long as possible:
1 Keep It Charged
As soon as you make it to shore, get the charger on your battery and keep it full. A Battery can get a type of “memory”, and if it is left partly charged more often than it is full, it tends to drain to that point more quickly.
