Questions about this item

What voltage does the 48Wh CI03XL battery operate at and what does that cap in practice?

It runs at 11.4V, which caps the maximum power delivery to the ProBook 640 G2, 645 G2, 650 G2 and 655 G2 motherboards.

What physical format must the battery match to fit the HP ProBook 640 G2, 645 G2, 650 G2 and 655 G2?

The CI03XL uses the exact internal moulding and screw-hole pattern for those four ProBook chassis, so it slots into the battery bay without adapters.

How is the CI03XL installed and which step do people often get wrong?

Power off, remove the bottom cover, unplug the old pack, connect the new CI03XL cable firmly, then replace the cover — many forget to seat the connector fully before screwing the case back.
