## Description

Keep your power source safe and toasty in these waterproof 3xAA battery holders. They're just like classic switched battery holders, but designed for survival! The case has a rubber gasket around the edge of the case (its black and hard to see in the photos but it is there) and attaches together with 4 machine screws. What Adafruit like about this design is that the hexnuts are captive in one side and you can assemble/disassemble as many times as you need. There's a potted power switch and a rubber-boot on-off switch (press to turn on/off). Use with any alkaline or rechargeable batteries for about 4.5V output.
 
 Would work great with Adafruit's [waterproof DC power plugs](https://core-electronics.com.au/waterproof-dc-power-cable-set-5-5-2-1mm.html) (just use heatshrink to waterproof the solder connections)
 
 **The power cable wires are not polarity marked, use any multimeter to verify the polarity during use.**
 
 They also have a 2xAA version when you need a smaller & lighter box
