The battery communicates with the laptop as it should, it works for a long time.
In the Dell E7440 manual it is written that the laptop supports 11.4v and 7.4v batteries. At first I thought it wouldn't fit, but the provision in the manual calmed me down. It actually works without any problems and fits perfectly in terms of size. ❤️💪👍️🔥

Frequently Asked Questions

Connected not loading, what should I do?

A problem with charging a new battery is rare with Green Cell models. However, if this is the case, the link below provides instructions on how to do this: https://www.youtube.com/watch?v=G4aWD3pmTIM

How can I extend the battery life of my laptop?

Just follow these 5 steps:

Avoid short charging times as the battery in our device has the number of charging times specified by the manufacturer.
Use batteries. Our rechargeable battery is designed for use. Continuous removal of the battery from the device does not have a positive effect on its condition.
Do not allow full discharge. Today's lithium-ion and lithium-polymer batteries are extremely sensitive to deep discharge. Repeated repetition of such a situation can cause irreversible damage to the battery.
Pay attention to the operating temperature. Temperature is an extremely important factor affecting the life of our battery. To ensure optimal temperatures, you should regularly clean your laptop's heat-dissipation system (with compressed air or a compressor) and avoid using the devices on soft surfaces (which can obstruct cooling vents).
Let the battery rest. If you plan to take a long break from using your laptop, remove the battery and place it in a dry, cool place. It is worth loading it to about 50% to avoid a complete discharge.

Is an 11.1V battery suitable if the previous battery is 14.4V?

The 11.1V battery is not used interchangeably with 14.4V and vice versa. This can cause permanent damage to your laptop. When choosing a new battery for your laptop, pay attention to the voltage at which the factory battery was. You can find this information directly on the battery.

Why are the batteries available in two versions, 10.8V and 11.1V, is that correct?

It is absolutely correct. Voltage differences result from different measurements and the cells used. It should be noted that such small voltage differences are not noticed by our laptop and do not affect its operation in any way.

Can the battery capacity (mAh) be larger?

It is possible to use higher capacity batteries. The battery capacity is expressed in milliampere hours (mAh), the higher the capacity value, eg 6800 mAh, the longer the working time can be achieved with one battery charge, which increases our mobility and independence.

How do I choose the right battery for my device?

Below are two ways to choose the right battery for your device.

device model
The tool model is usually located on the handle or on the body next to the motor of the device.
battery model
The battery code is located on the bottom of the battery, often it is a digital code, eg 194309-1, or mixed with letters, eg BL1830.

Can the battery capacity (mAh) be larger?

It is possible to use higher capacity batteries. The battery capacity is expressed in miles of ampere hours (mAh), the higher the value of the capacity, eg 3000 mAh, the longer the working time can be achieved on one battery charge, which increases our mobility and efficiency.

Laptop power supply - what voltage?

When choosing a new power supply for your laptop, you should check the voltage of the charger - this parameter should match your original device.

Is it possible to connect a weaker power supply to the laptop?

Using an AC adapter with a lower amperage than the original can cause a number of adverse changes in the operation of your laptop. For example, a power supply that is too weak can overheat because the laptop's components are not being supplied with sufficient power. We therefore recommend that you use chargers with the same or higher amperage.
