## Description

This battery holder connects 2 AA batteries together in series for powering all kinds of projects. Adafruit spec'd these out because the box is fairly slim, and 2 AA's add up to about 3V for many low voltage electronics projects, plus it has a nifty on-off switch. Fits any standard AA battery. When using rechargeable NiMH the output voltage will range from about 2.7V with charged batteries to 1.8V at the end of life with a nominal voltage of 2.4V. When using alkalines, the output will range from 3.2V with new batteries to 2.2V at the end of life with a nominal voltage of about 3V.The polarity matches that of Adafruit's [2-pin JST cable](https://core-electronics.com.au/jst-2-pin-cable.html) and [Li-Ion/Poly batteries](https://core-electronics.com.au/#). Uses a genuine JST connector so it won't 'catch and tear' in JST connectors.

This is **a great update to the battery packs that come with [micro:bit](https://core-electronics.com.au/search/?q=micro%3Abit)**'s because it has an on-off switch built in so you don't have to yank it out to turn off the power, and the AA batteries will last 3 to 5 times longer longer than AAA!
