Getac B300 and B300X replacement battery

The KingSener BP3S3P2900(P) is a 10.8 V lithium-ion pack rated at 8100 mAh and 88 Wh. It replaces part numbers BP3S3P2900, BP3S3P2900(P), 4418144000490 and 3ICR19/66-3 in Getac B300 and B300X rugged notebooks.

Verify part number and voltage before ordering

Confirm that the original battery carries one of the listed replacement part numbers and shows 10.8 V on its label. The Getac B300 and B300X chassis must accept the standard battery bay form factor used by these models. No other laptop series is supported by this pack.

Sustained discharge at rated capacity

The 88 Wh lithium-ion chemistry delivers steady voltage through a full workday of typical rugged-notebook workloads. Internal cell balancing maintains consistent output as the pack discharges from full to empty. Capacity remains stable across repeated charge cycles in demanding field conditions.

Questions about this item

Does the KingSener BP3S3P2900(P) battery ship with any tools or cables, or do I need to buy them separately?

The battery is a direct replacement unit for the Getac B300 and B300X. It installs without extra tools or cables, so nothing else needs to be purchased.

The title shows 8700mAh and 94WH while the specifications list 8100mAh and 88WH — which capacity should I expect?

The detailed specification for this model is 8100mAh and 88WH at 10.8V; the higher figures in the title are not the rated values for this battery.

Will the 88WH rating actually deliver longer field time on a Getac B300X compared with the original pack?

The 88WH capacity matches the original part numbers BP3S3P2900(P), 4418144000490 and 3ICR19/66-3, so runtime will be equivalent to the factory battery when new.
