This Dr. Battery unit is a new lithium-polymer pack rated at 2200 mAh and 15.2 V, delivering 33 Wh. It matches the original AC14B3K, AC14B8J, AC14B8K, KT.00403.027 and KT.0040G.004 part numbers. Compatibility spans Aspire V3-371, E3-111, E3-112, E3-112M, E5-771, ES1-311, ES1-411, ES1-421, ES1-431, ES1-511, ES1-512, V3-111, V3-111P, V3-112P, A515-51, A515-51G, A517-51 and A517-51G as well as Acer Chromebook 11 C-series units.
Voltage and connector must match exactly
The pack supplies 15.2 V; a different voltage will not work even if the physical shape appears similar. The built-in smart control chip manages charging current and provides short-circuit, overheat and overload protection. Lithium-polymer chemistry requires the laptop’s own charge controller to follow the correct profile. Using an incompatible adapter or bypassing the onboard circuitry can damage the cells or the system.
Capacity decides runtime per charge
At 2200 mAh and 33 Wh this battery stores a fixed amount of energy; actual running time depends entirely on the laptop’s power draw. Buyers who need longer unplugged sessions than the original cell provided will not gain extra capacity from this part. Verify the original battery’s model number and voltage before ordering.
