KingSener A41N1424 laptop battery 48WH 14.4V 14.8V 2600mAh 4-cell

Compatible replacement battery

The KingSener A41N1424 is a lithium-ion replacement battery built for Asus ROG GL552 series laptops and related ZX50 and FX models. It restores mobile power for owners of those machines who need a fresh 48 Wh pack. The four Japanese cells deliver 14.4 V or 14.8 V at 2600 mAh and the unit ships in black. Buyers whose laptop uses a different part number or form factor cannot use this battery.

Thermals and daily power draw

In normal use the pack runs at the laptop’s standard 14.4 V or 14.8 V rail and draws only the current the system requests. Lithium-ion chemistry keeps self-discharge low when the notebook is asleep or off. No active cooling is required because the battery sits inside the chassis and relies on the laptop’s own thermal design. There are no fans, pumps or external power bricks associated with this component.

Sustained load behaviour

Under continuous load the four-cell pack supplies up to 48 Wh before the laptop’s firmware initiates a low-voltage shutdown. Voltage will sag gradually as capacity depletes, a normal trait of lithium-ion cells. The pack contains no circuitry to boost output beyond its rated voltage, so heavy workloads that exceed the laptop’s power budget will still trigger the system’s own throttling. Runtime scales linearly with the power draw of the specific GL552 or ZX50 configuration.
