38 Wh replacement for HP JC03/JC04

This 38 Wh 2600 mAh battery replaces HP part numbers 919700-850 919701-850 and 919681-421. It fits HP 14-bs000 14-bw000 15-bs000 15-bw000 17-bs000 and 17-ak000 series notebooks. The pack is new and rated for more than 500 charge cycles.

Upgrade from a worn original pack

Swap this unit in when the factory battery no longer holds a useful charge or runs for less than the rated 3 hours. The jump is worth it when the original cell has dropped well below its 500-cycle design life. Buyers who need a higher-capacity pack than 38 Wh will not be served by this model.

Limits of the OEM form factor

The battery uses the exact JC03/JC04 mechanical envelope so it cannot exceed the original 38 Wh capacity. It connects through the proprietary HP connector used on the listed 14 15 and 17 inch chassis. Systems outside those series or packs requiring a different pin-out are not compatible.

Questions about this item

Does the 38 Wh JC03 JC04 battery fit the HP 14-bs000 series without a caddy?

It is a direct replacement for the original 919700-850 pack and slides into the same bay; no extra bracket or adapter is required.

Which step do people skip when swapping the 919701-850 battery in an HP 15-bw000?

Disconnect the internal cable before removing the old pack and reconnect it firmly; the latch clicks only when fully seated.

After how many cycles should I plan to replace the 2600 mAh JC04 cell?

The manufacturer rates it for more than 500 charge cycles before capacity drops noticeably.
