Sealed lead acid batteries and chargers power large devices and supply backup or reserve power for industrial systems. The batteries (also known as SLA or large-cell batteries) have a universal design that makes them ideal for replacing original batteries. Use a compatible charger to replenish the batteries for multiple uses. To prolong battery life, SLA batteries should be fully charged before storing them or installing them as backup power.

Batteries and battery chargers provide power and portability to electrical devices and equipment. Original equipment manufacturer (OEM) batteries can replace manufacturer-specific batteries incompatible devices such as cordless tools, lanterns, and two-way radios. Disposable, household batteries are commonly used in low-drain devices such as flashlights, remote controls, clocks, and smoke detectors. High-performance batteries provide increased capacity to handle spikes in power demand from high-drain devices such as digital cameras, thermal imagers, digital audio, drones, video game controllers, GPS equipment, and keyless entry systems. Rechargeable batteries can be used repeatedly without the need for constant replacement. Battery chargers replenish the power of depleted rechargeable batteries.
