Replacement Battery for HP 15-BS 15-BW 17-BS Series

This 11.1 V lithium-ion pack replaces the original JC03 unit in compatible HP notebooks. It fits the 15-BS 15-BW and 17-BS families along with several 15Q and 17-AK models listed in the compatibility data. The three-cell design delivers 31 Wh of capacity for mobile work or study sessions. Buyers needing a different voltage or a higher-capacity cell count will not be served by this part.

Practical Limits of the 11.1 V Lithium-Ion Interface

The battery operates at a fixed 11.1 volts and communicates with the laptop through the proprietary connector used by the listed HP series. Capacity is limited to 31 Wh, so runtime scales directly with the host system's power draw. Built-in circuitry provides short-circuit, overcharge, over-discharge and over-voltage protection. Units requiring a different pin-out, a higher voltage or a smart-battery protocol not covered by the listed part numbers will not function.

Check Your HP Model and Part Number Before Ordering

Verify that your laptop appears in the supported model list such as 15-bs0xx 15-bs1xx 15-bw0xx or 17-bs0xx and that the original battery carries a matching part number like JC03 JC04 919700-850 919701-850 HSTNN-LB7V or HSTNN-LB7W. Confirm the physical dimensions and connector orientation against the existing pack. Systems outside the listed series or using an unlisted part number cannot use this replacement.

Questions about this item

Which capacity matches the original 31Wh battery in my HP 15-bs series?

This JC03 replacement is rated at 31Wh and 2800mAh, the same capacity as the factory HSTNN-LB7V pack used in 15-bs, 15-bw and 17-bs models.

What does the 11.1V rating mean for daily runtime on a 15-bs laptop?

The 11.1V three-cell lithium-ion design delivers the voltage the notebook expects, giving runtime comparable to the original battery when new.

Does the battery use a proprietary connector or a standard HP interface?

It fits the same multi-pin connector used by HP part numbers 919700-850, 919701-850, HSTNN-LB7V and HSTNN-LB7W, so no adapter is needed.
