Buyers with a different laptop series or a battery rated at another voltage cannot use this unit. The part replaces OEM numbers PABAS207, PA3729U-1BAS, PA3729U-1BRS, PA3730, PA3730U-1BAS and PA3730U-1BRS only. Systems requiring a higher capacity or a different cell count should look elsewhere.

Voltage and capacity: 10.8 V, 4400 mAh, 48 Wh

These three figures must match the original battery label exactly; a mismatch means the pack will not charge or power the notebook correctly. Verify the numbers on your old battery before ordering.

Questions about this item

Does the 6-cell 48 Wh lithium-ion pack run hot or draw extra power when the laptop is used all day?

The 10.8 V 4400 mAh battery uses a smart control chip that manages charging and discharge, helping to limit heat build-up and power draw during extended use.

What must I already have to install this MPL16218P-03 battery in my Toshiba Qosmio?

You need a compatible Qosmio X500 or X505 series laptop that originally used a PA3729U, PA3730U or PABAS207 battery and a standard Phillips screwdriver for the battery bay.

Will this replacement work alongside the original AC adapter and charging circuitry in an older Qosmio X505-Q860?

Yes, the 10.8 V output matches the original specification and the built-in protection chip communicates with the laptop's existing charging system without modification.
