Charge a Battery

• Correctly charging your deep cycle AGM battery is crucial in maintaining performance. Overcharging your battery can damage the internal structure of the battery while undercharging can shorten its lifespan. The trick is to find the correct voltage for your battery, which in the case of AGM deep cycle batteries, is 14.7v.

Avoid Sulphation

• Sulphation occurs when the sulfuric acid within lead-acid batteries reacts to form a lead sulphate on the battery’s negative plates. The surface area of the acid on the plates is reduced, making it hard for the battery to hold its charge. The best way to prevent sulphation is by charging your battery before storage.

• If it is too late for that, try using a reverse pulse de-sulphation charger such as the 12V 8A Automatic Reverse Pulse deep cycle battery charger. The specialised battery charger can reduce effects of sulphation by using reverse pulse technology to limit the battery’s internal impedance while charging.

Use a Battery

• Keep the battery and connecting wires dry and clean to avoid leakage. Regularly clean the battery surface and connecting wires with a dry cloth. Do not use organic solvents to wipe. If the appearance of the battery is adversely affected, it should be replaced in time.

• Check the terminals regularly and there should be no looseness. Remove oxides from the terminals and wire joints, and strictly prohibit metal debris and other debris from entering the battery.

• Try to avoid deep discharge and over-discharge, the charge is best when the discharge depth is about 70% (that is, when the remaining power is about 30%).

• The battery should use the original charger and the charger matched by the regular manufacturer. After the battery is fully charged, it should not be charged for a long time to avoid overcharging and losing water. The charging process should avoid outdoor cold weather in winter and exposure to hot sun or other high temperature scenes in summer.

• When the battery is in storage, the battery should be fully charged and stored, and periodically recharged every other month to avoid sulphation and capacity loss of the battery plate.

• When the battery usage time is suddenly shortened sharply or the discharge performance is greatly reduced, it should be checked to a professional maintenance in time to check whether the charger, motor, battery, etc. are abnormal, and abnormalities are eliminated in time.

• During the use of the battery, the maintenance of single charge and single discharge is done every six months, which helps to extend the service life of the battery.
