Product Identity

This is a new 15.4V 54Wh lithium-ion replacement battery for select Samsung Notebook 9 and Notebook 9 Pro models. It matches part numbers AA-PBTN4LR, AA-PBTN4LR-05 and 4ICP5/43/97 and fits the extensive model list provided by the supplier.

Thermals and Power

The pack uses standard Li-ion chemistry at 15.4 volts and 54 watt-hours, delivering the voltage and capacity the original design expects. Normal operation stays within the thermal envelope defined by the laptop's own charging controller, with no additional cooling or power-draw concerns beyond the factory specification.

Deciding Specification

The single figure that determines fit is the 15.4V 54Wh rating combined with the exact part-number match; if your machine requires a different voltage or capacity this unit will not work. Buyers needing a higher-capacity pack or a different form factor should look elsewhere.

Questions about this item

How do I install the AA-PBTN4LR battery and which step is often missed?

Power off the laptop, remove the bottom case screws, disconnect the old battery cable, fit the new 15.4V 54Wh pack, reconnect the cable, replace the case and screws, then charge fully before first use.

What replacement will the AA-PBTN4LR battery need over time?

The lithium-ion pack will gradually lose capacity; after several hundred cycles it should be replaced with another AA-PBTN4LR or compatible 15.4V 54Wh unit.

What limit appears first on the AA-PBTN4LR during sustained heavy use?

The 54Wh capacity determines runtime; under continuous high load the battery will deplete faster and trigger the laptop's low-voltage shutdown.
