Electrical Specifications

The cell delivers 11.4 V and a capacity of 45 Whr using lithium-ion chemistry. Before ordering, confirm that your original battery shows the same voltage and watt-hour rating printed on its label. A mismatch in either figure will prevent correct operation or charging.

Build And Connector Layout

The pack is built as a direct drop-in module with the same mounting points and connector orientation as the factory unit. No tools beyond a standard screwdriver are required for the swap. Users who need hot-swap capability or an external charging dock will not find those features here.
