Direct Replacement Battery

The NShi WS04XL is a new lithium polymer battery rated at 7.7V and 66.52Wh capacity. It serves as a direct replacement for the original HP HSTNN-DB9Z, L97352-2D1 and L97357-005 cells. The pack is certified by CE, UL, FCC and RoHS and tested for over 500 recharge cycles.

Upgrade From Degraded Cells

This unit replaces a factory battery that no longer holds a useful charge or that shuts down under load. The jump is worth it when runtime has fallen below half of the original figure or when the laptop only runs while plugged in. It restores the original 66.52Wh specification without increasing capacity beyond the OEM design.

Straightforward Internal Swap

Installation requires opening the rear cover, disconnecting the old pack and fitting the new one so the connector seats firmly on the motherboard. The supplier advises using the original charger for the first cycles. Common issues are a loose connector or forgetting to remove shipping tape from the contacts before closing the case.
