Frequently Asked Questions
Q: Is my trolling motor battery bad?
A: The easiest way to tell if your battery is damaged is to check the specific gravity, which helps determine the concentration of acid in your water. Use a Hydrometer to test the electrolyte (acid+water) and specific gravity or density in a lead acid battery and to interpret the numbers the battery is no good if a cell is +/- 30 kg/m3 of another cell. 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.
Q: What Is The Right Way To Store My Trolling Motor Battery?
A: Exceptional care and maintenance of your battery are essential to retaining top performance throughout its service life. Make sure you never mix different types of batteries. Always keep the old and new batteries separate. The old batteries that aren't in use can be kept in a dark place that is slightly below room temperature.
Q: Should You Clean Your Trolling Motor Battery?
A: While you may not need to clean your battery, proper maintenance is an absolute must. Your battery will do its job to its best ability, and this is largely determined by how well it is maintained. You can clean it if you notice some corrosion on the terminals. Additionally, you should keep dirt and grime off the battery. If you are using a wet lead acid battery, be sure to fill it with distilled water occasionally. Tools like a hydrometer will help you determine the concentration of the acid substance.
AGM and gel batteries may be labeled maintenance free, but you can take some precautions to ensure optimal protection. Watch the charge because overcharging will ultimately compromise functionality. You should also keep an eye on the amount of energy drawn from the battery. Rather than drain it drain, aim to use only 75% of the charge. This may double the life of your trolling motor battery.
