AAA batteries

AAA batteries

— “Mini finger” or “little finger” batteries, a smaller analogue of “finger” AA batteries — diameter is 11 mm, length — 44 mm. Produced for cases where full-size AA elements would be too bulky, and a lot of energy is not required — in particular, they are popular in remote controls, and come across in ultra-compact cameras. The rated voltage is 1.5 V. But, unlike batteries, they are not rechargeable and are disposable.
