SummaryEditThe RE-Battery is a portable storage unit that holds up to 10,000 EU of power. It can be charged in all EU Storage units like the BatBox, MFE, or MFSU. It is used to craft many of the electric tools from IndustrialCraft2 and a few of the basic machines.
RE-Batteries do not stack when they have a charge. The stored power can then be used to power machines by right clicking the machine and placing it in the power supply slot. They can also be used to charge a handheld tool, by simply having both tool and RE-Battery in your hotbar, and right-click holding the RE-Battery.
