Dr. Battery MPL08217P-02 6-cell 4400 mAh 10.8V laptop battery

Replacement battery for HP and Compaq laptops

This 6-cell lithium-ion unit delivers 4400 mAh at 10.8 V and fits a long list of HP G50, G60, G61, G70, G71, HDX 16 and Compaq Presario CQ40, CQ41, CQ45, CQ50, CQ60, CQ61, CQ70 and CQ71 models. It is built for owners who need a direct swap for an ageing original pack. Buyers whose laptop uses a different voltage or cell count cannot use this unit.

Straightforward swap with basic precautions

The pack drops into the standard battery bay and locks with the existing latch; no tools are required beyond releasing the old pack. A built-in smart control chip handles charge management and provides short-circuit, overheat and overload protection. The most common issue is ordering the wrong part number, so verify the original battery code — such as 484170-001, 484171-001, 484172-001, 485041-001 or 497694-001 — before purchasing.

Steady output during extended sessions

The 48 Wh capacity supports multi-hour workloads without the voltage sag seen in worn cells. The protection circuitry keeps discharge stable under continuous load rather than only in short bursts. Users running demanding applications for long periods will notice consistent run-time until the pack reaches its low-voltage threshold.
