Questions about this item

The LA04 replaces part numbers VI04, HSTNN-DB6K, HSTNN-LB6K and 756478-421 used in the ProBook 440 G2, so it installs directly with no additional hardware.

Can I keep my original 14.8 V charger when I swap to this 38 Wh battery?

Yes, the LA04 operates at the same 14.8 V as the original battery, so your existing charger remains compatible.
