AAA Lithium Batteries
AAA lithium Batteries are a direct, non-rechargeable replacement for alkaline batteries of the same size. These batteries are extremely lightweight and provide better performance under load as well as a much longer shelf life than alkaline AAAs.
This case size is identical to the alkaline equivalent, measuring 10.5mm in diameter × 44.5mm long. It is commonly known as a “microlight” format and may also be called MN2400 or MX2400. This size is widely used in micro torches, wireless remote controls, clocks, calculators, toys, games and other consumer electronics. Output potential is 1.5V and the most typical configuration is a pair connected in series to provide 3V, although single-cell supplies are also common.
