Graphene Battery

Graphene batteries are made of a silicon oxide-graphene compound, which makes them lightweight and the most common type of battery. They are available in various shapes and sizes, and most of them are rechargeable. The Dragonguard utilized standardized power cells that consist of this battery technology, referred to as Small Tactical Universal Battery (STUB). STUBs have their own naming system for the different sizes of power cells. Additionally, the public has also adopted the Dragonguard's standards for consumer-grade products that require larger power cells, such as electric bikes.   Ten years after the initial development of graphene batteries, consumer-grade versions became available to the public. Since its inception, the Dragonguard has utilized this battery technology, which powered the laser that redirected lightning onto the Wyrm of Chaos, ultimately bringing an end to the Draconian War.   Standard battery sizes were established only after consumer-grade batteries became available. While old and outdated batteries may still be found, they are rare as no company manufactures them anymore. Most technology has been updated to use graphene batteries, which are generally smaller and more compact than the previous obsolete batteries. Additionally, graphene batteries have a slightly different shape, allowing them to be compatible with old sockets designed for cylindrical batteries.   Consumer-grade graphene batteries have a different shape compared to older battery types. While they are primarily cylindrical, they feature three slightly beveled edges which can prevent them from rolling. These bevels are small and rounded, allowing the batteries to be easily inserted into various sockets, including older full cylindrical types. However, graphene battery sockets are not compatible with the older battery styles due to their distinct shape.   Larger battery cells, often referred to as "power cells," do not maintain the same mostly cylindrical shape. Their size and weight necessitate more pronounced bevels. Proper alignment is crucial for safely inserting these larger batteries into sockets. Typically, if a power cell is very heavy or needs to be inserted at chest height or higher, the socket will have a lower inset bevel to assist with placement. This design allows the user to position the cell correctly before inserting it into the socket.
