This 2xAAA battery holder puts a nice finishing touch on your battery powered project. This holder features a sliding, removable cover as well as an ON/OFF switch which can be used to control power to your project.
The leads are about 150mm long, and the last 5mm of them are tinned.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

These are very cheaply made. The batteries will not make reliable contact unless a shim is inserted between the metal contact and the plastic case on the end opposite the wire leads.
I was working on a project that required some toying with voltage and amperage supply, and these battery packs are perfect for that. They were pretty good quality and I had no issues with them. I'd recommend them for projects for sure.
I ordered several of these and all of them are defective. One or both of the positive terminals do not make electrical contact with the battery terminal.
The gap is tiny - I needed a magnifying glass to see it - but it's there. I would upload a photo if I could.
