Direct replacement for HP TPN-I126 laptops

This 11.55V 41.5Wh lithium-ion battery replaces part numbers SG03XL, HSTNN-LB7E, 849048-421 and 3ICP6/60/80. It is built for owners of HP TPN-I126 series machines who need a new power source matching the original voltage and capacity.

Match the 11.55V and 41.5Wh rating exactly

The single specification that decides fit is the 11.55V voltage combined with the 41.5Wh capacity. A different voltage will prevent the laptop from charging or cause immediate shutdown. Verify the original battery label shows these two figures before ordering.

Simple swap once the bottom case is removed

Installation requires opening the laptop chassis and disconnecting the old pack; the connector is keyed to prevent reverse insertion. The most common issue is forgetting to detach the internal cable before lifting the motherboard, which can tear the fragile ribbon.
