Diamond battery

Diamond batteries, also known as Mantium batteries, are extremely long lasting power sources. The dalmer make use of nuclear fusion and fission for energy, and reuse the radioactivity from waste in order to make diamond batteries. The batteries are then used to power machines that require a low amount of energy for hundreds to thousands of years. These are typically to ensure the functioning of public utilities such as lighting, plumbing, satellites, vending machines, public displays and inputers and so forth.
These tiny batteries (around 5mm) are found everywhere in dalmer technology and are heavily reinforced to prevent radioactive leakage from the batteries. Every one of the trillions of batteries in circulation are chipped and tracked to prevent eventual leakage, or the fall of the technology in enemy hands.
Due to the innumerable references to diamonds in dalmer texts, the other races often spend considerable resources to find them, only to be disappointed when they find the supposedly worthless batteries.
The battery is basically two batteries in one. The main outer casing is where the radioactive material is stored which constantly emits heat energy at a low output, charging the inner casing. The inner casing has a higher output but emits power faster than it recharges. This means that the actual energy comes from the core, and while it has comparatively low energy storage compared to other batteries, it is constantly recharging.
As a rule of thumb, mantium batteries have a 50% efficiency for recharge time. For example it takes one hour for the core to power the device for 30 minutes.
Using two batteries to counter this problem doesn't work as there is energy loss between changes, meaning three batteries are required for optimal redundancy.
