Dr. Battery 14.8V 63Wh Replacement

This new lithium-polymer battery replaces Dell Alienware M11x and M14x series cells. It matches the original 14.8V voltage and 4257mAh capacity for direct compatibility. The black pack fits part numbers including 0DKK25 and 312-0984. Buyers with other laptop models cannot use this unit.

Upgrade From Degraded Original Pack

The jump is worth it when the factory battery no longer holds a usable charge or triggers shutdown under load. Dr. Battery cells are built to OEM specification and include a smart control chip for quicker charging and longer discharge time. Systems that require a different voltage or form factor are not supported.

Sustained Load Behaviour

Built-in protections guard against short circuit, overheat and overload during extended use. The lithium-polymer chemistry delivers stable output across the discharge cycle rather than a brief peak. Users needing hot-swap capability or a second battery for continuous operation will not find that feature here.
