A problem with charging a new battery is rare on Green Cell models. However, if this is the case, you will find instructions on how to do this in the following link:

Just follow these 6 steps:

1. Avoid short charging times, as the battery in our device has the number of charging times specified by the manufacturer.
2. Use batteries. Our rechargeable battery is designed for use. The continuous removal of the battery from the device has no positive effect on its condition.
3. Do not allow complete discharge. Today's lithium-ion and lithium-polymer batteries are extremely sensitive to deep discharge. Repeated repetition of such a situation may cause irreversible damage to the battery.
4. Pay attention to the operating temperature. Temperature is an extremely important factor influencing the life of our battery. To ensure optimum temperature values, clean the heat dissipation system of your laptop regularly (with compressed air or a compressor) and do not use the units on soft surfaces (which may obstruct cooling openings).
5. Let the battery rest. If you are planning a longer break from using your laptop, remove the battery and place it in a dry, cool place. It's worth charging it to about 50% to avoid complete discharge.

The 11.1V battery is not used interchangeably with 14.4V and vice versa. This can cause permanent damage to your laptop. When selecting a new battery for your laptop, be aware of the voltage at which the factory battery was present. This information can be found directly on the battery.

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

1. Device model
   The tool model is usually located on the handle or on the housing next to the motor of the fixture.
2. Battery model
   The battery code is located on the underside of the battery, often it is a digital code, e.g. 194309-1, or mixed with letters, e.g. BL1830.
