If you're looking for a pack of battery holders to meet your basic needs, this is a great option. You can easily create supplies to meet 3.3V, 5V, 9V, 12V needs, really whatever. The cases are good quality and it's easy to insert and remove batteries. The 9V connectors are particularly decent, they're a hard plastic which is easy to remove instead of that soft plastic that you sort of have to carefully peel off your battery terminals.

These are quite nice to work with. The wire is quite thin, probably 24 gauge or possibly even thinner -- but if you're trying to draw an amp or more from AAA cells, You're Doing It Wrong. The switch is in series with the negative contact and black wire; total resistance from the contact to the far end of the wire is less than 0.2 ohms. Wire on the 9V clips seems to be a notch or so heavier, but might just be tinned differently.Recommended.

These AAA battery boxes are nicely made with easy-to-remove covers to easily change out the batteries. They come with ample length of wire enabling the user to attach it to their project. The 9-volt adapters are a nice construction. They are firm which makes for easy battery changeouts.
