Self-Charging Battery
Self-charging batteries are a category of items that charge machines with a steady, infinite supply of power when put into the battery slot. They are made using various radioisotopes, with more expensive isotopes providing a better power generation rate.
Crafting
All self-charging batteries are made by combining two billets of an RTG fuel with an empty self-charging battery in a crafting grid:

Usage
To use a self-charging battary, they need to be inserted in the battery slot of any energy accepting machine, after which they will provide a constant flow of power, depending on which type is used.
| Battery | Power Output |
|---|---|
| Spent Fuel | 150 HE/t |
| Radium-226 | 200 HE/t |
| Technetium-99 | 500 HE/t |
| Cobalt-60 | 750 HE/t |
| Plutonium-238 | 1 kHE/t |
| Polonium-210 | 1.25 kHE/t |
| Gold-198 | 1.5 kHE/t |
| Lead-209 | 2 kHE/t |
| Americium-241 | 2.5 kHE/t |
However, if a self-charging battery is put inside a battery socket, its power output will fluctuate constantly, until it eventually causes a violent explosion, instantly killing any nearby entities with electric arcs that penetrate blocks, regardless of blast resistance. This makes them extremely unreliable for use in power generation.
Trivia
- Self-charging batteries are one of the only ways to generate energy out of generic nuclear waste, the other being the radiation-powered engine.
- The reason behind self-charging batteries exploding in a battery socket is due to Bob not wanting people to solely rely on it for power generation, since that is not their intended purpose.
