Replacement battery for Dell XPS 14 15 17 series
This 6-cell lithium-ion unit replaces the original Dell batteries listed under part numbers such as 0J70W7, 0JWPHF and 312-1123. It fits XPS 14, 15 and 17 models including the L501x, L502x, L701x and L702x families. The pack delivers 11.1 volts and 4400 milliampere-hours for 49 watt-hours of capacity. It is aimed at owners of those Dell notebooks who need a fresh power source.
Upgrade from a worn or failed original pack
When the factory battery no longer holds a useful charge or shows swelling, this new cell restores the laptop’s rated runtime. The jump is worth it if the machine otherwise meets your needs and you want to avoid a full system replacement. It is not for users whose chassis or motherboard has been damaged, nor for those who need a higher-capacity design than the original 49 Wh specification.
Limits of the 11.1 V 6-cell lithium-ion format
The chemistry and voltage are fixed by the original Dell design, so the pack cannot exceed the 49 Wh capacity without physical changes. Run-time will vary with workload, screen brightness and battery age. The built-in protection circuit guards against short circuit, overheat and overload, but it does not alter the fundamental energy ceiling of the 6-cell layout.

Questions about this item
Which Dell XPS models does the MPL05261P-27 battery fit?
It replaces the original Dell packs in XPS 14, XPS 15, XPS 17, XPS 17 3D, L401x, L501x, L502x, L701x, L701x 3D and L702x laptops.
What is the correct way to install the battery and what step is often missed?
Power off the notebook, disconnect the AC adapter, remove the bottom cover screws, unplug the old battery connector, fit the new 6-cell pack, reconnect the cable, refit the cover and screws, then charge fully before first use.
When will the 4400mAh 11.1V pack need replacing?
The lithium-ion cells gradually lose capacity over time; once run-time drops well below the original 49Wh level a new battery is required.
