Replacement battery for Latitude 3440 3540 E3440
This 41Wh lithium-ion pack is built for Dell Latitude 3440 3540 E3440 E3540 notebooks. It supplies 14.8V through four premium cells. The unit is new and carries CE and RoHS certification. It is not for owners of other Latitude models that use a different battery shape or connector.
Voltage and capacity limits of a 14.8V 41Wh pack
The 14.8V rating is fixed by the laptop's charging circuit; a higher or lower voltage pack will not work. Capacity of 41Wh sets the runtime ceiling, so heavy workloads will drain it faster than light use. The four-cell layout defines the physical size, so the battery bay must match exactly. Buyers who need longer unplugged time should look for a higher-capacity alternative.
Two distinct batteries exist for these models
Dell ships two incompatible batteries for the same Latitude 3440 3540 E3440 E3540 family. The only way to confirm fit is to compare the original battery against the product photos before ordering. Selecting the wrong variant will prevent installation. This listing covers the 41Wh four-cell version only.

Questions about this item
Which capacity should I choose for my Latitude 3440?
This battery is only offered in a single 41Wh 4-cell version rated at 14.8V, so there is no alternative capacity to select for the listed models.
What does the 41Wh rating mean for daily use on a Latitude 3540?
The 41Wh capacity indicates the total energy the pack can store; actual runtime depends on screen brightness, workload and power settings, but it is designed to match the original battery's endurance for the compatible Latitude models.
Does the 14.8V voltage limit which Latitude models can use this battery?
Yes, the pack is built for 14.8V systems and is confirmed compatible only with Latitude 3440, 3540, E3440 and E3540; other models requiring a different voltage will not work.
