Replacement for Dell Vostro and Inspiron
This Dr. Battery MPL05263P-27 is a new six-cell lithium-ion pack built to match OEM specifications for Dell Vostro 3360, 3460 and 3560 models. It also covers a wide range of Inspiron 14R, 15R and 17R variants including the 5420, 5520, 5720 and 7520 series. The 11.1 V output and 4400 mAh capacity restore factory runtime for compatible machines.
Smart control chip and protection circuits
An integrated smart control chip manages charging to reduce power consumption and extend discharge time. The pack includes short-circuit, overheat and overload safeguards that protect both the battery and the laptop during daily use. No extra software or drivers are required; the hardware functions automatically once installed.
11.1 V voltage must match your original
The single specification that decides fit is the 11.1 V output — your original battery must show the same voltage or the pack will not work. Capacity is rated at 4400 mAh, equivalent to 49 Wh, and the six-cell layout matches the physical profile of the listed Dell part numbers such as 0NHXVW and 312-1163. Buyers needing a different voltage or a higher-capacity nine-cell design should look elsewhere.

Questions about this item
Will the six lithium-ion cells need replacement after a certain number of charge cycles?
The 6-cell lithium-ion pack is rated at 4400 mAh and 49 Wh; capacity gradually declines with each full cycle, so plan on a new battery when run-time no longer meets your needs.
What stops the battery from delivering full current during a long, heavy workload?
The built-in smart control chip enforces short-circuit, overheat and overload protections that will throttle output if temperature or current exceed safe limits.
How warm does the pack get and how much power does it draw when the laptop runs all day?
The 11.1 V, 4400 mAh design and the smart chip’s lower-consumption charging keep heat and draw within normal laptop-battery ranges for the listed Dell models.
