Please know that the above information is for the previously manufactured battery batch. You can refer to the below picture for the newly manufactured battery batch. The production date of the new battery pack is now in the QR code information.

Lithium batteries, like any other type of battery, have a certain lifespan. This is because batteries work by producing electrical energy through chemical reactions, and these chemical reactions will gradually weaken over a certain period of time, resulting in a decline in battery performance.

Please note that battery life is also affected by the environment in which it is used, such as temperature and humidity. Therefore, if you notice a decrease in battery performance or the battery is no longer able to continuously power your device, replace the old battery with a new battery as soon as possible.
