A dual-purpose trolling motor Fish Finder Battery battery has two functions – starting and deep cycling the motor. One of those minor drawbacks is that they usually cost more than their wet cell and AGM counterparts. Another is that they are sensitive to overcharging and require a charger that is suitable for gel cell batteries to prevent premature failure or damage. They cost almost double wet cells, although their improved performance and better lifespan mean they still offer great value for money. They do need a bit of maintenance though, namely refilling water levels and checking for corrosion, and are typically heavier than most other batteries.

AGM batteries work well in the cold but are not so reliable in hot environments. Again, this does mean a higher price point, although it often works out similarly priced (if not cheaper) to buying several cheaper-priced batteries over the same period. The durability is quite surprising because dual-purpose batteries traditionally struggle to last as long as a dedicated deep-cycle battery. Small batteries tend to have around 25 Ah, while mid-sized batteries hover around 50 Ah, with the largest batteries having 100+ Ah. This battery is built to be sturdy and resist any form of vibration or shock.

Charge your batteries immediately after use, and keep them plugged into the appropriate charger until they are 100 percent charged.
