What do I need to be aware of when I receive a new laptop battery?

How should I do if the battery is not recognised?

Update BIOS to latest version. Power off, disconnect battery (and adapter), hold power button 20s, reconnect battery and adapter, reboot. If still not recognised, reseat battery and clean contacts.

What should I do if the battery expands?
