Professional Series Replacement

This Dr. Battery Professional Series unit is a lithium-ion replacement battery rated at 10.8V and 4400mAh for 48Wh. It is built for owners of compatible Asus ASUSPRO models who need to restore original runtime. The cell chemistry and voltage match the factory specification for direct installation.

Safety Protection Circuitry

The integrated protection board provides short-circuit, overheat and overload safeguards during charge and discharge cycles. These circuits are designed to maintain safe operation across the supported laptop range without requiring additional software or configuration. The battery arrives new and ready to use.

48Wh Capacity Envelope

The 48Wh rating supports typical office workloads on the listed Asus ASUSPRO devices, including the P2430, P2530, P2540, P4540 and PU551 series. Runtime will decrease under sustained high-load tasks or when the cell ages beyond its design cycle count. Buyers needing longer unplugged time or a higher-watt-hour pack should look elsewhere.

Questions about this item

How many charge cycles before the lithium-ion cells in this 4400mAh battery need replacement?

The lithium-ion cells do not have a published cycle rating; capacity will gradually decline with each full charge and discharge.

What limits runtime first when the 10.8V pack runs continuously under load?

The 48Wh capacity sets the total energy available, so runtime ends when the stored charge is depleted.

Does the battery get hot or draw extra power during all-day operation?

Built-in short-circuit, overheat and overload protections limit temperature rise and prevent excess current draw during extended use.
