## Description

This battery holder connects 2 AAA batteries together in series for powering all kinds of projects. Adafruit spec'd these out because the box is nicely slim, and 2 AAA's add up to about 3V for low-voltage electronics projects, plus it has a nifty on-off switch. 

Fits any standard AAA battery. When using rechargeable NiMH the output voltage will range from about 2.7V with charged batteries to 1.8V at the end of life with a nominal voltage of 2.4V. When using alkalines, the output will range from 3.2V with new batteries to 2.2V at the end of life with a nominal voltage of about 3V.

The polarity matches that of Adafruit's [2-pin JST cable](https://core-electronics.com.au/catalog/product/view/sku/ADA261) and [Li-Ion/Poly batteries](https://core-electronics.com.au/#). Uses a genuine JST connector so it won't 'catch and tear' in JST connectors.

This is **a great update to the battery packs that come with [micro:bit](https://core-electronics.com.au/search/?q=micro%3Abit)**'s because it has an on-off switch built in so you don't have to yank it out to turn off the power.

## Technical Details

- Cable Length: 6" long, terminated with a genuine JST-PH 2 pin connector
- Holder Dimensions: 62.5 x 25.3 x 15.4mm

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4191:1` (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/ADA4191:1.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; `search.md?q=` also works)
