The maintenance on a VRLA battery is much easier than the Conventional types. There is no need to check electrolyte levels and the filler plugs should never be removed. *The term “Maintenance-Free”, which is applied to all VRLA batteries, has to do with the fact that no addiional water is ever required.

 Keep the battery and terminal posts clean. If required, follow the cleaning procedures outlined in the How to Maintain Conventional Batteries section.

 Check the battery voltage and charge if necessary. Full charge voltage for a VRLA Maintenance-Free battery is 12.8V to 13.0V. When charging the battery, refer to the manufacturer’s instructions provided with the charger.

** CAUTION! Before performing any maintenance to your battery, make sure you have the adequate personal protection gear. It’s necessary to shield your eyes, skin, and clothing. Also, never smoke near a battery or expose it to an open flame or sparks. Read the owner’s manual and follow the instructions and all warnings included with the battery.
