Replacement battery for Asus X551 series

This 4-cell lithium-ion pack delivers 2600mAh at 14.8V and is built to fit Asus X551, X551C, X551CA and X551MA models. It replaces original part numbers including 0B110-00250100, A31N1319 and A41N1308. The unit ships new from the manufacturer with Grade A cells and integrated circuit protection against short circuit, overheat and overload.

Fits directly into the existing battery bay

No additional adapters, cables or BIOS updates are required; the battery uses the original connector layout and secures with the laptop's own latch mechanism. Installing it restores mobile operation without occupying a USB port or requiring an external charger. The pack is certified to UL, CE, FCC and RoHS standards for electrical safety and environmental compliance.

Provides roughly 1.5 hours of typical runtime

Actual duration varies with screen brightness, processor load and peripheral use. The 2600mAh capacity supports up to 500 recharge cycles before noticeable capacity loss. It is not suited for users who need all-day unplugged operation or the ability to hot-swap a second pack during extended sessions.
