Replacement Battery for Samsung Chromebook 3

This lithium-ion pack is built for Samsung Chromebook 3 models including the XE500C13, XE501C13, NT500R3M and NT500R3W series. It replaces part numbers such as AA-PBUN2TP and BA43-00373A. The cell is sold new and intended for owners whose original battery no longer holds a useful charge. It is not for users of other laptop brands or newer Samsung ranges.

Thermals and Power in Daily Use

The 7.6V 33Wh two-cell design matches the factory voltage and capacity, so heat output and run time stay close to the original specification. Typical operation sees the pack warm slightly under load but within normal limits for a Chromebook chassis. No active cooling is required and the unit draws power only when the system requests it. Battery life varies with screen brightness, wireless use and workload.

Build Quality and Connector Fit

The pack uses a direct-fit connector that aligns with the existing battery bay, so installation needs no adapters or cable routing. Screw holes line up with the original mounting points for a secure fit. The housing is rated for up to 500 recharge cycles over its service life. Buyers who need a higher-capacity pack or a different voltage should look elsewhere.

Questions about this item

How do I install the AA-PBUN2TP battery in my Samsung Chromebook 3 and what step is often missed?

Power off the Chromebook, remove the bottom case screws, disconnect the old battery connector, fit the new 2-cell 7.6V pack, reconnect the cable, then reattach the case; the step often missed is reconnecting the battery cable before closing the chassis.

What maintenance or replacement will the 33Wh Li-ion pack need later?

The battery is rated for up to 500 recharge cycles; after that capacity drops noticeably and a replacement AA-PBUN2TP or BA43-00373A unit will be required.

What limit appears first during sustained use of this 4400mAh battery?

The 33Wh capacity is the first limit; under continuous load the pack will deplete before thermal or cycle-life limits are reached.
