Sealed Lead-Acid (SLA) Batteries

Sealed lead-acid (SLA) batteries for UPS systems, alarm and security panels, emergency lighting, medical equipment, mobility devices, and general 6V/12V backup power. SLA batteries are reliable, inexpensive, and available in a wide range of amp-hour capacities and form factors.

Looking to upgrade? Many of these can be replaced with a LiFePO4 lithium battery of the same voltage and size — typically 50–70% lighter, with 5–10× the cycle life and more usable capacity. Match the voltage and terminal layout to find the right battery for your device.
