Compatible Asus Pro B451 series replacement

This Cameron Sino DS-CS-AUP451NB lithium-ion battery fits Asus Pro B451, B451JA, B451JA-1A, B451JA-XH52 and B451JA-FA083G models. It replaces original part numbers 0B200-01120000 and B31N1407 with a black 4.2 Ah unit. The pack is brand new and built to OEM specifications.

Lithium-ion chemistry and voltage limits

The cell operates at 11.4 V and stores 47.88 Wh across its 4200 mAh rating. Lithium-ion packs cannot be charged below freezing or above 45 °C, and deep discharge below the protection threshold will lock the pack. No circuitry in the battery itself prevents swelling if the laptop runs hot for long periods.

Upgrades worn or failed original packs

This unit replaces an exhausted or swollen factory battery that no longer holds a useful charge. The jump is worth it when the laptop shuts down unexpectedly, reports a permanent fault code or physically bulges the chassis. It does not add capacity beyond the original 47.88 Wh design.
