- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA3784:1.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.

## Description

Here's another addition to Adafruit's growing family of [AA battery holders](https://core-electronics.com.au/#). A holder for four (4) AA batteries! It's got an 8" long power cable with a 2.1mm DC jack at the end, and, oh yes, it's in classy Adafruit black.

4 x AA battery packs are best used with development boards with 2.1mm DC jacks and can run with ~4.8V (4 x NiMH) to ~6V (4 x Alkaline). Great for powering boards with a ~4.5-6.5V DC input allowance as you'll see that range depending on how fresh the batteries are.

DC plug is 5.5mm OD, 2.1mm ID with center-positive polarity.

**AA Batteries are not included**, [but Adafruit have lots of options in the store!](https://core-electronics.com.au/search/?q=alkaline%20aa)

### Technical Details

- Holder Dimensions (excluding cable): 62.5 x 57.3 x 16mm
- Cable length: 8" / ~200mm
