A sealed lead acid battery, or SLA, battery refers to a low maintenance, valve controlled battery, that is rechargeable. You may find your SLA batteries no longer take a full charge and run out very quickly after a period of use. Do not throw these batteries away because you can easily repair them yourself. The steps are easy but it will take a lot of waiting time to get the batteries back to form.
