E-buy A31-X101 10.8V 2200mAh laptop battery

Replacement Battery for ASUS Eee PC X101

This 10.8V 2200mAh lithium-ion pack replaces the original A31-X101 or A32-X101 battery in ASUS Eee PC X101, X101C, X101CH and X101H ultraportables. It restores full mobility to compatible white or black chassis models with a direct-fit design. The three-cell construction matches OEM dimensions and connector placement for a straightforward swap.

Practical Limits of the 10.8V Li-ion Interface

The battery delivers 23.76Wh at a fixed 10.8V nominal voltage, so runtime scales directly with the laptop's power draw rather than any adjustable profile. Built-in circuitry guards against overcharge, short circuit and overheating, but cannot increase the fundamental energy capacity. Performance will degrade gradually over repeated cycles as with all lithium-ion chemistries.

Capacity and Headroom for Ultraportable Use

At 2200mAh the pack typically yields two to four hours of mixed workload on these low-power netbooks, varying with screen brightness and wireless activity. It comfortably covers a standard commute or classroom session but will not sustain a full workday without recharging. Heavy multimedia playback or continuous Wi-Fi use pushes runtime toward the lower end of that range.
