This unit fits the Latitude E7270 and Latitude E7470 models when the existing battery matches the listed part numbers such as 21X15, KNM09 or TX283. Buyers who need a different voltage, a higher watt-hour rating or a battery for another laptop series should look elsewhere. Always verify the part number on your current battery before ordering.

Installation uses the laptop's native battery compartment and connector without extra cables or adapters. Conditioning the new pack by completing several full charge and discharge cycles helps optimise it to its full capacity. The battery restores mobile runtime for the supported Latitude systems.
