There are plenty of differences between traditional car batteries people are used to and deep cycle marine batteries. Aside from the main differences, being deep cycle marine batteries are composed of thicker active battery plates and are actually submerged in electrolyte fluid, they are quite different to maintain as well.
Eliminate Corrosion Thoroughly as Possible
Eliminating corrosion from your battery is imperative to maintaining optimum performance. Effectively a softening and shedding of lead from the plates or terminals, excessive corrosion can lead to all out failure. This is due to diminished cycle count and destroyed insulation between negative and positive charges. Once corrosion is eliminated using a professionally recommended corrosion removing spray, be sure to apply protective, anti-corrosive battery coating spray.
Water Your Battery
Because your golf cart battery is a lead acid flooded deep cycle marine battery, it has to be watered regularly. You should at least check your battery levels once a month to ensure water levels meet regular levels. If the level needs adding, be sure to use distilled water to avoid inadvertently adding any impurities to your deep cycle system. Don’t ever use tap water, as the minerals from this source will quickly accumulate and diminish the life of your battery. Be careful not to overwater, however, as to avoid diluting the electrolyte levels.
If you have to charge your deep cycle battery, be sure to use a heavy duty charging chord. Using a lightweight chord generates heat resistance and could pose a pretty serious fire hazard. Also when charging, make sure your battery charger and battery are well ventilated. If your deep cycle battery is under the seat, make sure it’s open as to prevent explosive hydrogen gas from accumulating.
