Green Cell Battery will restore the mobility of your Apple MacBook Air 13 A1932 A2179 (2018, 2019, 2020) laptop Thanks to the Green Cell battery your laptop will have a new life. The use of high quality components and a perfect fit will restore laptop mobility. You can easily mount it on your device and you can be sure of full compatibility with electronic and notebook software. To achieve maximum efficiency and battery life, the following has been applied: High Quality Green Cell Lithium Ion Cells Modern Control Electronics ABS Resistant Case Everything is done with precision and thoroughly tested. High Quality Green Cell Lithium Ion Cells The Green Cell Lithium Ion Cells are proven batteries with real high capacity, high durability and no memory effect. They are the heart of the battery and provide a long working time. Their use results in: Great capacity - 48Wh - 2200mAh (24Wh) - is 20% more than other batteries with non-brand low-quality cells High durability - cells can stand up to 1000 charging cycles, which results in 2-3 years of operation without problems. Their capacity falls very slowly and after 300 charging cycles (about 1 year of operation) still hold more than 80% of the modern electronic control capacity Thanks to it, the battery communicates with the laptop providing information on the charging status, the residual charge rate, the missing time before completing the charging cycle. Most models use electronic systems from the renowned Texas Instruments company, also used in the original batteries. This guarantees: 100% matching with computer electronic controllers - the battery communicates with the laptop exactly like the original battery Advanced protections - protection from excessive discharge, overload and thermal protection that ensures the correct and safe operation of the battery Execution accuracy High quality materials and carefully studied form make sure: The battery is perfectly compatible and easy to mount The structure is durable and protects sensitive electronic cells and circuits. Replace the battery, not the PC! A new battery is a better and cheaper alternative to replacing the computer. Not only will you save money, but you will also take care of the environment. Your laptop will have new life and we will take care of recycling.
