Batteries

Electrical gadgets and equipment rely on batteries and battery chargers for power and portability. Low-drain gadgets like flashlights, remote controls, clocks, and smoke detectors frequently use disposable household batteries. High-capacity batteries allow high-drain devices like digital cameras, thermal imagers, digital audio, drones, video game controllers, GPS equipment, and keyless entry systems to tolerate surges in power consumption. Rechargeable batteries can be used multiple times before needing to be replaced. Battery chargers restore the power of rechargeable batteries that have been depleted.
