What this battery replaces

The Dr. Battery MPL03249P-27 is a 4 cell lithium-ion pack rated at 14.4V and 2200 mAh. It is built as a direct replacement for a long list of Asus models including the X450, X452, X550 and K550 series.

Protection circuits guard against short circuit, overheat and overload during extended use. The manufacturer states the design maintains OEM specification levels for reliable performance over time.

Questions about this item

Does the 4 cell 14.4V design run hot or draw extra power during all day use?

The 4 cell lithium ion pack operates at the standard 14.4V and 2200mAh rating, matching the original specification so heat and power draw stay within normal limits.

What must I already own for this MPL03249P-27 battery to work in my laptop?

You need a compatible Asus model such as X450L, X550 series, A450, F550, K550, P550 or an original battery numbered A41-X550, 0B110-00230000 or 0B110-00230100.

Will this 32Wh replacement work alongside the original charger and motherboard in an older Asus X550CA?

Yes, the 14.4V 2200mAh cell count and smart control chip are built to OEM spec, so it charges and communicates normally with the existing charger and system board.
