Also known as T501-Non-Rechargeable Energy Storage Unit, each Single-Use Battery can store up to 1000 EU. That's 9000 EU less than their rechargeable counterparts... and you can't recharge them.Like RE Batteries, right-clicking will recharge the electric tools currently in your inventory, using the Single-Use Battery. However, they are much easier to produce in quantities and are easier to transport.

Single-Use Batteries produce more energy than simply burning coal in a Generator.
- Coal makes 4000 EU if burned.
- Redstone is worth 500 EU.
- Macerating coal into dust costs 625 EU.
Ignoring the costs of making cables and hydrating the dust, the total potential energy of these ingredients are 4000+500+625= 5125 EU
From that you get 8000 EUs worth of batteries-- who needs the law of conservation of energy?! Not you!
You only have to think of what's worth more: 2875 EU and the portability, or a Cable and Redstone.
Just don't forget to hydrate the coal dust!
