Although energy stored in batteries is pretty much as inefficient and costly as it gets, some projects rely on it. We have a couple of the most common battery types available. Please either donate the suggested donation or restock them if you need them.

Are you interested in "regular" or rechargeable batteries?

Primary Cells

Primary cells are non-rechargeable batteries commonly used in handheld devices.

Suggested Tools:

9 V "block" batteries can short each other, take care when storing them! Keep them in separate compartments to prevent them from discharging or even starting a fire.

We'll stock some snap connector cables soon that attach to 9 V blocks on one side and end in bare wire on the other one.

Secondary Cells

Secondary cells are rechargeable and can be found in phones, laptops and cars. They vary quite a bit in terms of capacity, charging and handling. When using rechargeable batteries in projects, sophisticated charging and protection circuits need to be in place to avoid damaging the cells or even prevent failures (don't do this!).

Here's a decent instructable about salvaging batteries from electronics junk.
