Replacement Battery for Latitude E-Series

This 97Wh lithium-ion unit replaces the original power pack in Dell Latitude E5420, E5530, E6420, E6430, E6520, E6530 and E6540 models. It also fits select Precision, Vostro and Inspiron systems listed in the compatibility data. The 11.1V black cell arrives new and ready to install.

11.1V Lithium-Ion Cell in Black Housing

The battery uses a standard lithium-ion chemistry rated at 11.1V and 97Wh, matching the electrical specification of the factory pack. Its form factor aligns with the existing bay, so no chassis modification or adapter cable is required during the swap.

Upgrade from Lower-Capacity Packs

Owners running the smaller 48Wh or 62Wh packs will gain a measurable increase in unplugged runtime. The jump is worth it when daily work keeps you away from a power outlet for extended periods. Users whose machines already shipped with a 97Wh unit simply restore the original endurance.
