Replacement battery for HP and Compaq laptops
This 6-cell lithium-ion pack replaces original batteries in HP G71, G71t, HDX 16, HDX 16T, G50, G60, G60t, G61, G70 and Compaq Presario CQ40, CQ41, CQ45, CQ50, CQ50T, CQ50Z, CQ60, CQ60Z, CQ61, CQ70, CQ71 models. It supplies 10.8 V and 4400 mAh capacity for users who need a direct drop-in power source. Buyers with laptops outside these listed series should verify their original part number before ordering.
Installation notes and common issues
The pack fits the standard battery bay on the listed models and locks with the existing latch mechanism. No tools are required beyond releasing the old pack and sliding the new one into place until it clicks. A frequent mistake is ordering without matching the original part number such as HSTNN-W51C, HSTNN-W52C, HSTNN-XB72, HSTNN-YB72, 462889-121, 462890-251, 462890-421 or 462890-542, which leads to returns.
Behaviour under sustained load
The integrated smart control chip manages charging current and discharge rate to keep cell temperatures stable during extended use. Built-in protection circuits guard against short circuit, overheat and overload conditions when the laptop draws continuous power. The 48 Wh rating supports typical office and media workloads over long sessions without rapid voltage sag.
