FAQ

What is an SLA battery?

An SLA (sealed lead-acid) battery is a type of rechargeable battery that uses lead plates and sulfuric acid as its electrochemical components. It’s "sealed" because it doesn’t require regular maintenance or refilling of water, unlike traditional flooded lead-acid batteries.

Can SLA batteries be recharged?

Yes, SLA batteries are rechargeable. They can be recharged using a standard lead-acid battery charger. However, it’s important to use the correct charger to avoid overcharging, which can shorten the battery’s lifespan.

How long do SLA batteries last?

SLA batteries typically last between 3 to 5 years, depending on usage, charging habits, and environmental factors. They generally offer around 200 to 500 charge cycles before the battery’s capacity begins to degrade.

How do I maintain an SLA battery?

While SLA batteries require little maintenance, it’s important to keep them clean, ensure proper ventilation, and store them in a cool, dry environment. Avoid deep discharges, as they can damage the battery. Regularly check the charge level to ensure it doesn't drop too low.
