NShi IZKROR KN02XL 37.2Wh 4835mAh 7.7V laptop battery

Replacement Battery for HP Pavilion x360 11-AD

This 37.2Wh lithium polymer battery replaces the original KN02XL unit in HP Pavilion x360 Convertible 11-AD and 11M-AD series laptops. It delivers 7.7V from a two-cell configuration rated at 4835mAh. The part matches OEM numbers HSTNN-LB7R, HSTNN-UB7F, 916365-421, 916365-541 and 916809-855. Buyers needing a different voltage or form factor cannot use this pack.

Sustained Use Over 500 Recharge Cycles

The cell chemistry is rated for more than 500 full recharge cycles while maintaining usable capacity. Built-in circuit protection guards against overcharge, over-discharge and short circuits during long sessions. Using the original charger keeps the management circuit in sync with the laptop firmware. Heavy workloads that drain the pack in under an hour will still count as a single cycle.

Limits of the 7.7V Two-Cell Interface

The laptop expects a precise 7.7V nominal input; higher or lower voltage packs will not communicate with the embedded controller. Capacity is fixed at 37.2Wh, so runtime scales directly with system power draw and cannot be extended by firmware. The black casing fits only the listed 11-inch x360 chassis; larger 13-inch or 14-inch models use a different battery shape.
