Dell 11.1V 5200mAh 6-Cell Lithium-Ion Battery

This replacement battery fits Dell laptops using part numbers J70W7, JWPHF, R795X, WHXY3, 312-1123, 312-1127 and 453-10186. It restores mobile power for users whose original pack no longer holds a useful charge. The 6-cell lithium-ion design delivers 5200mAh capacity at 11.1V. Buyers needing a different voltage or form factor should look elsewhere.

Thermals noise and power draw

Lithium-ion chemistry generates minimal heat during typical office or media workloads. The pack operates silently because it contains no moving parts. Power draw matches the laptop’s own regulation circuitry, so there is no extra strain on the charging system. CE and RoHS certifications confirm compliance with safety and environmental standards.

Upgrade from worn original pack

This unit replaces a depleted or swollen factory battery that causes short runtimes or unexpected shutdowns. The jump is worth it when the old pack delivers less than half its rated capacity or forces constant tethering to an outlet. It is not for users who need a higher-capacity 9-cell alternative or a second hot-swappable pack for continuous operation.

Questions about this item

How do I install this 6-cell 5200mAh battery in my Dell laptop and what step causes problems?

Power off the laptop and unplug the AC adapter before removing the old pack; the step people get wrong is forgetting to fully seat the replacement so the locking latches click on both sides.

What maintenance or replacement will this 11.1V lithium-ion pack need later?

Lithium-ion cells lose capacity over time; when run time becomes too short for your needs the pack must be replaced as the cells are not user-serviceable.

What limit appears first on this 6-cell battery during sustained heavy use?

The 5200mAh capacity sets the total energy available; under continuous high load the pack will reach its discharge limit sooner than under light use.
