## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA771:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA771:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## 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
