Professional Series replacement battery

This Dr. Battery Professional Series unit replaces the original power source in Acer TravelMate 8372 and 8481 TimelineX laptops. It uses OEM-grade Li-ion cells rated at 14.4V and 4400 mAh to deliver stable output for business and everyday productivity tasks. Integrated protection guards against over-charge, over-discharge, overheating and short-circuit conditions. Confirm your original part number and voltage before ordering.

Thermals and power behaviour

The Li-ion chemistry and built-in safety circuitry maintain consistent voltage during normal office workloads without excessive heat buildup. No moving parts means silent operation under typical use. The battery draws power only during charging cycles and supplies steady current to the notebook when unplugged.

Upgrade context and fit

This pack replaces Acer part numbers AS09B5E, AS10I5E, BT.00405.011, BT.00805.016F and NCR-B/428 across the listed TravelMate models. The jump is worth it when the original pack no longer holds sufficient charge for a full work session. Buyers needing a higher-capacity cell or a different form factor will not be served by this specific 4400 mAh unit.
