Replacement Battery for Acer Aspire Laptops

This lithium-ion battery replaces original packs in numerous Acer Aspire 2xxx and 4xxx series notebooks. It supplies 11.1 volts and 6600 milliampere-hours for 73 watt-hours of capacity. The black pack is sold new and includes built-in protection against short circuit, overheat and overload. Buyers whose laptops use a different voltage or connector cannot use this unit.

Lithium-Ion Chemistry and Voltage Limits

Lithium-ion cells deliver their rated capacity at 11.1 volts and degrade gradually with charge cycles and age. The integrated safety circuit stops charging if temperature or current exceeds safe thresholds. Runtime varies with workload, screen brightness and power-management settings. Users needing longer unplugged time than a single pack provides must carry a spare or use external power.

73 Wh Capacity Decides Fit

The 73 watt-hour rating determines whether this battery meets the runtime target for a given Acer Aspire model. Check the original part number against the compatibility list before ordering. Systems requiring a higher or lower watt-hour pack will not operate correctly with this unit.
