Deep cycle batteries are designed to be discharged down as much as 80% time after time, and have much thicker plates. The major difference between a true deep cycle battery and others is that the plates are SOLID Lead plates-not sponge.
Simple Guidelines for Extending Battery Life. 1  Allow a fully saturated charge of 14â16 hours. 2  Always keep lead acid charged. 3  Avoid deep discharges. 4  Never allow the electrolyte to drop below the tops of the plates. 5  Never add acid. 6  Use distilled or de-ionized water. 7  When new, a deep-cycle battery may have a capacity of 70 percent or less.
