Dr. Battery MPL05259P-08 6-cell 11.1V 4400mAh laptop battery

Replacement Battery for Dell Vostro

The Dr. Battery MPL05259P-08 is a new six-cell lithium-ion pack built to replace the original Dell batteries used in Vostro 1710, 1710N, 1720, V1710 and V1720 laptops. It delivers 11.1V and 4400mAh for a 49Wh rating, matching OEM voltage and capacity specifications. Buyers who need a different voltage, a higher capacity or a battery for another laptop series cannot use this pack.

Thermals Noise and Power Draw

The internal smart control chip manages charge current to reduce heat during charging and lowers power consumption while the laptop runs on battery. Protection circuits guard against short circuit, overheat and overload conditions, keeping cell temperatures stable during normal discharge. No active cooling is required and the pack operates silently inside the chassis.

Upgrade From Worn Original Cells

This unit replaces Dell part numbers 312-0740, 312-0741, 312-0894, 451-10611, 451-10612, G278C, G279C, G280C, G282C, P721C, P722C, P726C, T117C, T118C, Y026C, Y027C, Y028C and Y029C when the original pack no longer holds a useful charge. The jump is worth it when runtime has dropped below half of the original 49Wh figure or when the laptop shuts down unexpectedly under load.
