SLA Batteries

Sealed Lead Acid (SLA) batteries are used in many different applications such as uninterruptible power supply (UPS), alarm systems, emergency back-up, medical, & much more.


Rechargeable, Maintenance-Free Batteries

Whether you’re powering your business equipment or personal scooter, you need to know your battery will go the distance and give you the performance you can count on.

Sealed Lead Acid (SLA) batteries are rechargeable, lead-acid batteries where the electrolyte is sealed. The most significant difference between SLA batteries and other lead-acid batteries is that the electrolyte doesn’t flow freely, so the battery does not need regular fluid top-offs. SLA batteries require much less maintenance than their flooded lead-acid counterparts.

You may see SLA batteries called VRLA batteries, which stands for Valve-Regulated Lead Acid, because these batteries feature a pressure release valve to regulate the battery’s interior pressure from excess gas buildup.
