This adorable little coin cell battery holder is great for small, portable, or wearable projects. It holds two 20mm coin cell batteries (also known as CR2032) in series to generate 6V nominal. 20mm coin cells are popular as they are used in keychain lights and remotes, so they are easy to get and fairly low-cost. They tend to have about 220mAh capacity.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4988:1` (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/ADA4988:1.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.)
