Replacement Battery for HP and Compaq Laptops

This 6-cell lithium-ion battery replaces original packs in HP G50, G60, G61, G70, G71 and HDX 16 series as well as Compaq Presario CQ40, CQ45, CQ50, CQ60 and CQ70 models. It delivers 10.8V and 4400mAh capacity for owners who need a direct replacement for part numbers such as 462890-542 or 484170-001.

Installation and Common Issues

The pack fits into the standard battery bay and locks with the existing latch, so no tools are required beyond releasing the old unit. Problems usually arise when the laptop model or original part number is not verified first, leading to a mismatch in voltage or physical shape.

Practical Limits of a 6-Cell Lithium-Ion Pack

A 6-cell design at 10.8V provides a fixed energy capacity of 48Wh, which limits runtime compared to higher-cell alternatives. The chemistry also means capacity will gradually decline with charge cycles, and the pack cannot supply power beyond its rated voltage or current specification.
