Compatible Asus X551 Series Replacement

The KingSener A41N1308 is a lithium-ion laptop battery built for Asus X551, X551C, X551CA, X551M and X551MA models. It matches the original dimensions so installation requires no modification. The pack uses Korean cells and a quality PCB to deliver reliable mobile power for daily computing.

Sustained Discharge Stability

Korean Li-ion cells maintain stable voltage output during extended workloads rather than dropping off after a short burst. The protection circuit guards against over-charge, over-discharge and short circuits throughout each cycle. Regular full charge and discharge cycles help the pack retain its rated capacity over months of use.

37 Wh Capacity Decides Fit

At 37 Wh and 2600 mAh the battery determines how long the notebook runs away from mains power. Buyers needing significantly more runtime will find this capacity limiting. The 14.4 V rating must match the original specification; a different voltage pack will not work.
