Fits inside the existing chassis without extra parts

The battery uses the original connector layout so it slots into the same bay and screws into the current mounting points. No additional cabling, adapters or BIOS updates are required, and the black finish matches the factory look. Built-in overcharge, overdischarge, over-temperature and short-circuit protection guards the notebook during every charge cycle.

Two screwdrivers included for immediate installation

A Phillips and a Torx driver ship in the box, letting you remove the bottom cover and swap the pack without hunting for tools. The cell chemistry is rated for up to 1000 recharge cycles, supporting long-term daily use. Buyers who need a higher-capacity pack or a different voltage will need to look elsewhere.
