Questions about this item

How long will the 47 Wh capacity keep my EliteBook 840 G3 running on a full charge?

The 47 Wh rating means the pack stores 47 watt-hours of energy; actual run time depends on your workload, screen brightness and power settings.

Does the 11.4 V output match the original HP CS03XL battery voltage exactly?

Yes, the replacement is rated at 11.4 V, the same nominal voltage as the HP CS03XL and HSTNN-DB6U packs it replaces.

Will this battery fit inside my ZBook 15u G4 without any case modification?

It is built to the same form factor as the original HP 800513-001 and CS03XL batteries, so it seats directly in the existing battery bay.
