Replacement battery for Dell 52TWH

This 51Wh 7.6V lithium-ion pack replaces the original Dell 52TWH, MM6M8 and XX3T7 cells. It is aimed at owners of compatible Dell notebooks who need a fresh power source after the factory unit has degraded. Buyers whose laptop uses a different part number or voltage should look elsewhere.

Four premium cells and safety certifications

The pack uses four premium-quality lithium-ion cells rated at 51Wh and carries CE and RoHS marks. These certifications confirm compliance with European safety and environmental standards, so the battery meets baseline requirements for over-charge, over-discharge and thermal protection without adding extra software or hardware features.

Straightforward swap with visual verification

Installation consists of removing the old pack and fitting this one in its place; no tools beyond a small screwdriver are typically required. The supplier stresses that you must compare the physical battery with the product photos before fitting, because case shape and connector orientation can vary even within the same model series.
