Replacement battery for Samsung Chromebook 3 series

This new lithium-ion pack delivers 7.6 V and 33 Wh across two cells, matching the original AA-PBUN2TP specification. It fits the XE500C13, XE501C13, NT500R3M and NT500R3W model families listed by the manufacturer. Buyers whose Chromebook uses a different part number or form factor cannot use this unit.

Direct swap for the internal pack

The battery occupies the same bay as the factory unit and connects to the existing motherboard header without adapters or cables. No external charger or docking station is required for normal operation. Systems that need a higher-capacity cell count or a different voltage rail are not supported by this design.

Rated for up to 500 recharge cycles

Capacity is specified at 4400 mAh and the supplier notes that actual run time varies with device load and usage patterns. The pack is shipped new from the manufacturer and should be cycled to about 5 % for the first calibration. Users who need guaranteed runtime figures beyond the rated cycle count will not find them here.
