The Durahell Battery is a key item that stores crafting time.
Description[]
Each crafting slot has its own Durahell Battery that stores crafting time. There are 7 Durahell Batteries, one for each crafting slot. Battery will provide crafting time to its slot until completely depleted. Battery will fill with crafting time when:
- A craft is completed
- Slot is unused
- "Skip x hours of crafting time" overflows (skips more time than the craft takes)
The efficiency of a battery determines what percentage of time will be stored in the battery. Also, the efficiency determines the speed at which the battery will be charged.
For example: When a craft is completed or when a slot is unused, at 20% efficiency, it will take 5 seconds for the durahell battery to recharge 1 second.
It works the same for overflow time. At 25% efficiency, if you overflow your craft by 1 hour, It will add 25% of an hour (15min) to the battery.
Upgrading[]
Each Battery can be upgraded to improve its capacity or efficiency. In order to upgrade you need to have required number of 
Arcane Power Cells.
