HP 15.4V 70W 4-Cell Laptop Battery L08855-855 L08934-1B1 SR04070XL-PL

HP 15.4V 70W 4-Cell Battery

This replacement battery uses lithium-ion technology to supply 15.4 volts and 70 watt-hours of capacity across four cells. It is designed for HP laptops that require part numbers L08855-855, L08934-1B1, SR04070XL or SR04070XL-PL. The pack carries CE and RoHS certifications and includes a one-year manufacturer warranty. It suits users who need a direct power-source swap for a depleted original unit.

Simple Slide-In Replacement

Installation typically requires removing the bottom case screws, disconnecting the old pack and snapping this unit into the same bay. No soldering or firmware updates are involved. The most common issue is a loose connector if the retaining clip is not fully seated, which can cause intermittent charging. Ensuring the battery ribbon clicks into place eliminates that problem.

Verify Part Number Before Ordering

Confirm that your laptop's service tag lists one of the four compatible part numbers printed on the original battery label. The voltage must read 15.4V and the cell count must be four; a different voltage or cell configuration will not fit or function correctly. Check that the chassis battery bay matches the physical dimensions of a standard four-cell HP pack.
