Questions about this item

How does the CMOS battery keep the BIOS clock running when the LG LW25-B3HD laptop is turned off?

The lithium cell powers the real-time clock circuit on the motherboard so the date and time stay correct even when the main battery is removed or drained.

What connector does this replacement battery use to attach to the motherboard?

It uses the standard two-pin JST-style plug that matches the original LG LW25-B3HD CMOS header.

Will this battery fit inside the LG LW25-B3HD chassis without modification?

Yes, the cell and cable length are built to the same dimensions as the factory part so it slides into the existing battery compartment.
