Replacement battery for Dell Latitude E7440

This 7.7 V lithium-polymer pack replaces original Dell batteries including part numbers 34GKR, 0D47W and 3RNFD. It fits the 14-inch 7000 Series Ultrabook models E7440, E7440 Touch and E7450. The unit is supplied new with a one-year warranty.

Voltage-specific compatibility limits

The battery only works with the 7.4 V version of the original pack; Latitude E7450 ships with two different voltage variants so the original label must be checked. A mismatched voltage will prevent correct operation and could damage the laptop.

Upgrades a depleted or failed original pack

It restores runtime when the factory battery no longer holds charge or triggers a replacement alert. The swap is worthwhile when the laptop otherwise meets the user's needs and the original part number matches the listed compatibles. Buyers whose machines require a different voltage or form factor cannot use this unit.

Questions about this item

Should I pick the 7.7 V 52 Wh version or the 7.4 V alternative for my Latitude E7450?

The E7450 ships with two distinct battery voltages; this unit is 7.7 V / 52 Wh, so verify the voltage printed on your original battery before ordering.

What does the 52 Wh rating translate to in daily use on an E7440?

52 Wh at 7.7 V equals 6700 mAh, giving a typical full-day runtime on the 14-inch Ultrabook depending on workload and screen brightness.

Does the 7.7 V spec limit compatibility to certain Dell part numbers?

Yes — this replacement matches Dell part numbers such as 34GKR, 0D47W, 3RNFD and the 451-BBFS series only when the original battery is also rated 7.7 V.
