Included instructions and protective packaging

The box contains one battery and a printed instruction sheet. Sponge or bubble wrap protects the cell during transit so it arrives without physical damage. The instructions guide the owner through the removal of the old pack and the installation of the new one. Buyers who need additional tools or adhesive strips must source them separately.

Black lithium-ion cell for internal mounting

The battery uses a black Li-ion casing designed to sit inside the laptop chassis and connect to the existing motherboard header. No external cables or adapters are required once the back cover is removed. Build quality follows standard laptop-battery construction with rigid corners that align to the mounting points. Users who cannot open the device or who need a hot-swappable power solution will not be served by this internal pack.

Questions about this item

When will the 42Wh Li-ion pack need replacement?

The 11.52V battery delivers 42Wh and 3653mAh; cycle life varies with usage, so expect to replace it when run-time no longer meets your needs.

What limits runtime during a full day of work?

The 42Wh capacity sets the total energy available; sustained loads will drain the 3653mAh cell faster than light tasks.

Does the battery get hot or noisy during all-day use?

The pack has no moving parts and runs silently; normal warmth may occur under heavy load but it produces no fan noise.
