Replacement battery for Asus U33 U42 U43 U52 U53

This new Dr. Battery MPL03243P-01 unit is a six-cell lithium-ion pack rated at 10.8 volts and 4400 milliampere-hours. It is built to match OEM specifications for the listed Asus ultraportable and mainstream laptop families. The black casing and integrated smart control chip provide short-circuit, overheat and overload protection for daily mobile use.

Six-cell lithium-ion build

The six-cell layout delivers 48 watt-hours of energy while the onboard chip manages quicker charging, lower power consumption and longer discharge time. A standard laptop battery connector mates directly with the motherboard socket on compatible models, so installation requires no soldering or adapter cables. The physical dimensions follow the original A31-U53, A32-U53, A41-U53 and A42-U53 form factor for a secure fit in the battery bay.

Verify model number voltage

Check the label on your existing battery for the exact Asus model name or the original part numbers such as A31-U53, A32-U53, A41-U53 or A42-U53. Confirm that the output voltage printed on the old pack reads 10.8 volts. This unit is not suitable for laptops that use a different cell count, voltage or connector keying.
