Compatible Asus replacement battery

The Dr. Battery DRPROAS278P-01 is a lithium-ion replacement unit rated at 11.25V and 2200mAh for 25Wh. It targets owners of listed Asus A540, F540, R540 and X540 series notebooks whose original A31N1519 pack no longer holds a useful charge.

Fits listed models without modification

The pack matches the voltage and connector layout of the original battery, so it seats directly in the existing bay. Built-in short-circuit, overheat and overload protections operate automatically, leaving the laptop’s charging circuit and firmware unchanged.

Restores runtime on aging A31N1519 systems

This unit replaces a depleted or swollen A31N1519 battery in the compatible Asus models listed above. The upgrade is worthwhile when the original cell chemistry has degraded below usable capacity and the laptop otherwise meets the user’s needs.

Questions about this item

How long does the 2200 mAh capacity last under sustained use?

The 2200 mAh lithium-ion cell delivers 25 Wh at 11.25 V, so runtime depends on the laptop's power draw; heavier loads deplete it faster.

Does the battery get hot or noisy during all-day operation?

The pack has no moving parts and includes overheat protection; it runs silently and should stay within normal temperature limits for a lithium-ion replacement.

Which original Asus battery number must match for this replacement to work?

It replaces the Asus A31N1519; confirm that number on your old battery before installing.
