KingSener B31N1635 42WH 11.52V laptop battery

Replacement Battery for VivoBook Pro 17

This KingSener B31N1635 battery replaces the original power source in compatible Asus VivoBook Pro 17 models including the A705U, N705U, A705UA and X705 series. It is a new lithium-ion unit rated at 42WH and 11.52V with a capacity of 3653mAh. The part matches the original dimensions for direct installation without modification. Buyers seeking a higher-capacity alternative will not find it here.

Voltage and Capacity Limits

The battery operates at a fixed 11.52V and delivers 42WH of energy, which defines the maximum runtime available from a single charge. Lithium-ion chemistry provides stable output but capacity will diminish gradually with age and charge cycles. The supplier advises a full charge and discharge cycle two or three times initially to calibrate the cells. Continuous connection to an AC adapter while the battery is installed can accelerate degradation.

Compatibility Checks Before Ordering

Verify the original battery part number on your laptop; it should read B31N1635 or the listed substitutes 0B200-02560100 and 0B200-02560000. Compare the physical layout and connector position with the product images to ensure a proper fit. The unit is designed for the specified VivoBook Pro 17 series only and will not suit other Asus ranges or different form factors. Store at more than 80% charge if removed for extended periods.
