Replacement Battery for Dell Inspiron 14z

This new Dr. Battery MPL05304P-05 replaces original Dell part numbers 2NJNF, 8JVDG, T41M0 and TPMCF. It fits Inspiron 14z (5423), 14z Ultrabook, 14Z-5423, 15z (5523) and 15z-5523 models. Buyers who need a battery for a different Dell series cannot use this unit.

Lithium Polymer Cell with Integrated Protection Chip

The black lithium polymer pack delivers 11.1V and 3950mAh for a 44Wh energy rating. A built-in smart control chip manages charging, reduces power consumption and extends discharge time. Short-circuit, overheat and overload safeguards are included. Users who require a removable legacy cylindrical-cell design will not find it here.

44Wh Capacity Defines Runtime Limits

The 44Wh rating sets the practical ceiling for unplugged use on compatible ultrabooks. Actual runtime varies with workload, screen brightness and system power management. Buyers who expect all-day operation on a single charge without access to mains power may find the capacity insufficient.
