## Description

This battery holder connects 3 AAA batteries together in series for powering all kinds of projects. Adafruit spec'd these out because the box is slim, and 3 AAA's add up to about 3.3-4.5V, a very similar range to Lithium Ion/polymer (Li-Ion) batteries and have an on-off switch. That makes them ideal for use with 3.3V projects that have a 2-pin JST connector meant for one of Adafruit's Li-Ion/Poly batteries. (Of course, you can't recharge them like Li-Ion/Polys, so don't try to plug this into one of Adafruit's Li-Ion/Poly charger boards!)
 
 Fits any standard AAA battery. When using rechargeable NiMH the output voltage will range from about 3.7V with charged batteries to 2.7V at the end of life with a nominal voltage of 3.6V. When using alkalines, the output will range from 4.6V with new batteries to 3.3V at the end of life with a nominal voltage of about 4.5V
 
 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 wont 'catch and tear' in JST connectors.

## Technical Details

 Box Dimensions: 2.5" × 1.45" × 0.62"
 Cable: 6" long, terminated with a genuine JST-PH 2 pin connector
