myVolts 4741 laptop battery 4400mAh 49Wh 11.1V 6-cell Li-ion

Compatible 6-cell lithium-ion replacement

This 4400mAh 49Wh 11.1V battery replaces original packs in a wide range of Acer Aspire and TravelMate notebooks as well as select Gateway and Packard Bell models. It is built for owners who need a direct-fit replacement for a worn or failed original unit. The 6-cell lithium-ion chemistry matches the voltage and capacity specifications listed for the supported part numbers.

Voltage compatibility and capacity ceiling

The pack operates at 11.1V and is marked compatible with 10.8V systems, so it fits laptops designed for either nominal voltage without modification. Capacity is fixed at 4400mAh and 49Wh; runtime will follow the host device's power draw and cannot exceed this rated energy store. No higher-capacity version is offered under this model number.

Snap-in form factor and everyday handling

The battery uses the standard slide-in latch mechanism found on the listed Acer chassis, so installation requires no tools and the pack sits flush with the bottom case. Its 6-cell brick adds modest thickness at the rear but keeps the original footprint, allowing the laptop to rest flat on a desk and fit existing sleeves. The lithium-ion cells are sealed in a rigid housing that resists flex during daily insert and remove cycles.
