The present disclosure discloses an electric tool power supply detachably installed on an electric tool, the electric tool power supply. The electric tool power supply comprises a power supply component, a first output interface, and a second output interface. The power supply component is configured to store and provide electrical energy. The first output interface is electrically coupled to the power supply component. The power supply component is configured to provide operating voltage for the electric tool through the first output interface. The second output interface is electrically coupled to the power supply component. The second output interface is further configured to electrically coupled to a starter of a vehicle. The power supply component is configured to output instantaneous large-current to the starter through the second output interface to start the vehicle.

A cell case includes (i) first and second metal plates constituting a first part of the cell case and placed such that the first and second metal plates are separated from each other (ii) a resin portion provided between the metal plates such that the resin portion connects the first and second metal plates. The first metal plate and the second metal plate include a first overlapped portion and a second overlapped portion, respectively, such that the first overlapped portion and the second overlapped portion overlap with each other via the resin portion. The first overlapped portion includes a hook. The second overlapped portion has an opening. The hook is formed to be caught on the opening to restrict relative displacement between the first metal plate and the second metal plate along a direction where the first metal plate and the second metal plate are separated from each other.
