Renew your favorite laptop

Thanks to the Green Cell battery, the laptop gains new life. The highest quality components and perfect fit restore the laptop's mobility. It can be easily inserted into the device, and you can be sure that it is fully compatible with the notebook's electronics and software.

To achieve the highest efficiency and durability of the battery, the following have been applied:

High-quality Green Cell lithium-ion and lithium-polymer cells

Modern control electronics

Durable ABS plastic housing

The battery is manufactured precisely and thoroughly tested.

High-quality lithium-ion and lithium-polymer Green Cell cells

The Li-Ion/polymer Green Cell cells are tested batteries with high real capacity, great durability, and no memory effect. These are the heart of the battery and ensure long lifespan. Their use provides:

• High durability - the cells can withstand up to 1000 charging cycles (PRO and ULTRA versions), resulting in 2-3 years of trouble-free operation. Its capacity decreases very slowly, and after 300 charging cycles (about 1 year of operation), they still retain more than 80% of their capacity

Modern control electronics

This allows the battery to communicate with the laptop, providing information about the charge status, remaining working time, or time remaining until full charge. Most models use Texas Instruments electronic circuits, which are also used in original batteries. This guarantees that:

• 100% compatibility with the computer's electronics and drivers - the battery communicates with the laptop just like the original cell

• Advanced protection - over-discharge, over-charge, and thermal protection ensure the proper and safe operation of the battery

Factory precision

The highest quality materials and precisely reproduced shape ensure that:

The battery fits perfectly into the laptop case and can be easily inserted

The housing is physically resistant and protects the sensitive cells and electronic circuits

Replace only the battery, not the entire laptop!

The new battery is a better and more economical alternative than replacing the laptop. It not only saves money but also cares for the environment. Your favorite laptop gains new life, and we take care of recycling.
