Adafruit Accessories Waterproof 3xAA Battery Holder (1 piece)
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 we 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.
