Direct replacement battery

The NShi AA-PLYN4AN is a lithium polymer battery built to replace the original Samsung AA-PLYN4AN unit in the XE550C22-A02US XE550C22-H01 XE550C22-H01UK series notebooks. It delivers 7.4V and 50Wh 6800mAh capacity in a black plug-and-play package. Buyers who need a different voltage or a higher watt-hour rating will not be served by this model.

Build integration

Installation requires opening the back case to verify the original part number matches AA-PLYN4AN before fitting the new cell. The battery connects directly to the existing connector without extra cables or adapters. A one-year warranty covers the unit. Builders who cannot access the internal compartment or who use a different Samsung series cannot use this battery.

Sustained operation

The supplier recommends an initial conditioning cycle: discharge to 5% then charge to 95% and repeat three to four times. For storage beyond one month, keep the charge above 80% and avoid leaving the AC adapter connected continuously during use. Users who regularly drain the cell to zero or store it empty will see reduced longevity.

Questions about this item

How long will the 50Wh 6800mAh capacity last before the voltage drops under heavy load?

The 50Wh 6800mAh lithium polymer cell delivers its rated capacity at 7.4V; runtime depends on the laptop's power draw, so a high-load workload will deplete it faster than light use.

Does the battery run hot or make noise when the laptop is used all day?

As a solid-state lithium polymer pack it has no moving parts and generates no audible noise; normal warmth occurs during charge or discharge but excessive heat suggests a system issue.

Which Samsung laptop models must I already own for this AA-PLYN4AN to fit?

It is a direct replacement for the Samsung XE550C22-A02US, XE550C22-H01 and XE550C22-H01UK series; verify the original battery part number matches AA-PLYN4AN before ordering.
