Replacement battery for ASUS U36 series

The KingSener A42-U36 is a new lithium-ion pack built to replace the original battery in compatible ASUS U36 laptops. It delivers 5600mAh at 14.88V for 83Wh of energy using eight Korean cells. The unit matches the factory dimensions so installation requires no modification.

Li-ion chemistry and single-voltage operation

The pack supplies a fixed 14.88V output determined by its eight-cell series layout. Capacity is rated at 5600mAh with no allowance for higher or lower voltage modes. Runtime scales with the host system's power draw and cannot exceed the 83Wh design limit.

Black housing with integrated protection circuit

A built-in PCB manages charge and discharge cycles to guard against over-current and short-circuit events. The casing mirrors the original battery profile ensuring a secure latch and flush fit. Cells are rated for stable capacity when conditioned with two to three full cycles and stored above 80% charge during long idle periods.

Questions about this item

Should I choose the A42-U36 or the A41-U36 part number for my ASUS U36?

Both part numbers refer to the same 8-cell, 14.88V, 5600mAh battery; pick whichever matches the label on your original pack.

What does the 83Wh rating mean for daily runtime on my U36?

The 83Wh design capacity typically delivers several hours of mixed use, with actual time varying by screen brightness, workload and power settings.

How does the 14.88V voltage affect compatibility with the original charger?

The 14.88V nominal voltage matches the factory specification, so the standard ASUS adapter charges it normally without any extra hardware.
