Batteries

A battery is an energy source that converts chemical energy into electrical energy and powers portable devices independently of the mains. It is used in battery-powered devices and circuits such as remote controls, flashlights, measuring instruments, clocks, toys, smoke detectors, car keys and motherboard memory backup. In this category, Varta-branded AA, AAA, D and 9 V batteries, lithium button cells such as the CR2032, 12 V specialty batteries such as the A23, NiMH rechargeable batteries and a battery charger are listed in separate subcategories. Choose the battery size and rated voltage according to the device's battery compartment and label, the chemistry according to the device's current consumption, and the single-use or rechargeable type according to how often you use it. The rated voltage of alkaline AA batteries is 1.5 V and that of NiMH rechargeable batteries is 1.2 V; for rechargeable batteries, the capacity given in mAh shows the amount of charge the battery can deliver on one charge. NiMH rechargeable batteries are the common choice for devices that consume batteries often, and alkaline batteries for devices that stay on standby for a long time and draw little current.
