A collector plate assembly includes a collector plate and a collector plate support, the collector plate having a welding part for welding to a terminal of a battery unit, and the collector plate being installed in the collector plate support in such a way that the welding part is exposed by the collector plate support. A battery pack includes a housing; a battery support, enclosed by the housing and supported in the housing, the battery support being electrically connectable to an electric tool to supply electric power to the electric tool; and a collector plate assembly including a collector plate support and a collector plate installed in the collector plate support.

The present invention relates to a battery housing for a vehicle battery, comprising at least two wall elements, stacked one above the other in a stacking direction, in order to form in each case a housing wall, wherein each wall element comprises a pair of a through bore and a threaded bore, arranged next to the through bore in a plane perpendicular to the stacking direction, for screwing on a wall element which is directly adjacent in the stacking direction, wherein the threaded bores and through bores are arranged alternately one above the other with reference to the stacking direction; it moreover relates to a vehicle battery with such a battery housing.

An apparatus for defining an AC power source having a predetermined amperage rating and for use with a pallet truck or fork lift lifting device. The apparatus includes a pair of terminal banks, a battery, a converter adapted to change DC to AC power, a relay, a controller, and a base adapted for engagement by the lifting device for transport of the apparatus. The apparatus is shaped so that it can be transported by the lifting device through a doorway. A pair of terminal banks, battery, converter, relay and controller are coupled to one another and configured for selective operation in a standalone configuration or a stacked configuration.

An air compressor more reliably protects a battery pack without lowering its operability for attachment to and detachment from a battery mount. The air compressor includes an electric motor driven on power from a battery pack having six faces, an operation unit operable to connect or disconnect power to the electric motor, an compression unit driven by the electric motor to produce compressed air, a tank that stores the compressed air, a battery mount that receives an attachment face of the battery pack, and a guard defining a protective area to contain the battery pack and the compression unit. The battery pack is attachable to the battery mount with at least three of the six faces exposed.

The present disclosure is directed to a reversible battery tray that has a plurality of first boundary reception areas at a first side, and a plurality of second boundary reception areas at a second side opposite to the first side. The first boundary reception areas have a first shape to receive a first type of battery with a corresponding second shape, and the second boundary reception areas have a third shape to receive a second type of battery with a corresponding fourth shape. The reversible battery tray may be positioned within a battery box such that the first side is exposed or the second side is exposed as selected by a user or an operator of a vehicle to utilize different types of batteries while also restraining movement of the selected type of battery by the user or the operator as well.
