Batteries - SLA

About

Sealed lead-acid (SLA) batteries provide reliable, rechargeable power for applications needing steady energy delivery and robust performance. Their sealed, maintenance-free design makes them a solid choice for backup power systems, emergency lighting, solar energy storage, and other heavy-duty uses. Each SLA battery is built with lead plates and a sulfuric acid electrolyte that is either immobilized in a glass mat (AGM) or gel form, making the pack spill-proof and safe to handle. Cells typically provide around 2V each, so a 12V pack contains six cells. SLA packs deliver strong current output and can support high-drain or long-duration loads, while remaining durable and stable under load or in standby service. Because they are sealed and valve-regulated, SLA batteries can be used in virtually any orientation. They resist leaks, handle vibration and rough environments well, and do not require periodic maintenance such as watering. For users seeking dependable, rugged, rechargeable power, whether for tools, emergency lighting, or backup systems, SLA batteries remain a cost-effective and proven solution.
