lithium batteries How to check the production date
The production date of lithium batteries is very important for the safe and healthy use of lithium batteries, how can I check the production date of lithium batteries?
First, through the battery shell to check the production date
The production date of lithium batteries can usually be found on the battery casing. Some battery manufacturers will engrave a time stamp or a code containing date information on the battery shell. For example, if the battery is engraved with “2018.12”, it means that the battery was produced in December 2018.
Second, check the production date through the battery label
Some lithium batteries are not directly labeled with the date of production on the battery shell, but there may be a code on the label, which can be used to determine the date of production. For example, the battery label may be labeled with “YYMMDD” date format, in which YY represents the last two years, MM represents the month, DD represents the date. For example, the code on the label is “181211”, which means the battery was produced on December 11, 2018.
Third, check the production date through the code on the package
In some cases, the production date of lithium batteries can be found on their packaging. Some manufacturers print the production date of the battery on the package or mark some specific codes or identifiers to trace the production history of the battery. Users can use this information on the package to determine the date of production of the battery.
It should be noted that lithium batteries usually have a service life of 3-5 years, so if you find that the battery has been used for a long time and the battery capacity is gradually decreasing, then you should consider replacing the battery. At the same time, the use of lithium batteries also need to pay attention to the process of maintenance, including avoiding over-discharge, avoiding high-temperature environments, the use of appropriate chargers and so on.
In short, the above methods can easily determine the factory date of lithium batteries, which is very important for maintaining the safety and healthy use of batteries.
