HP 15.4V 70W Laptop Battery

This 15.4V lithium-ion battery delivers 70W of capacity across four premium cells. It is built as a direct replacement for HP part numbers 916678-171, 917678-171, 917678-181 and 917678-271. The unit carries CE and RoHS certification and includes a one-year warranty. It suits owners of compatible HP notebooks who need to restore original runtime.

Who this suits and who should look elsewhere

This battery fits users whose HP laptop requires one of the listed part numbers and who want a new, certified lithium-ion pack with a full one-year warranty. Buyers with a different HP part number or a non-HP machine cannot use this unit. Anyone needing a higher watt-hour rating or a different voltage should look at other options.

Fitting it into your build

Installation is a simple swap: remove the old pack and insert this one using the existing latch mechanism. No tools, cables or firmware updates are required. The battery occupies the standard bay, leaving all ports, drives and expansion slots free. Once seated, it charges through the laptop’s normal AC adapter and reports capacity to the operating system immediately.

Questions about this item

Does this 15.4 V 70 W battery need any extra cables or a separate charger to work?

It installs directly inside the laptop and charges through the existing AC adapter, so no extra cables or external chargers are required.

Will this 4-cell 917678 pack fit alongside the original 916678-171 battery already in my HP?

This unit replaces the original 916678-171, 917678-171, 917678-181 or 917678-271 battery; it is not designed to run in parallel with another pack.

How can I confirm the 15.4 V 70 W replacement is working correctly after I install it?

The laptop should power on without the adapter, the OS battery meter should show charging and discharging normally, and runtime should match the 70 Wh rating.
