The model of the finished battery (referring to the one that has completed the packaging process) is determined by consultation between the customer and the battery manufacturer. Lithium battery cell types are divided into square cells and cylindrical cells. The cell model is determined by size. A square battery cell such as 496587 means the battery cell is 4.9mm thick, 65mm wide and 87mm long. Cylindrical batteries like the classic 18650 have a diameter of 18 mm and a length of 65 mm.
Polymer batteries can be added with aluminum shells. After adding aluminum shells, they can be used but cannot be used for diving.
Lithium polymer battery is a type of lithium battery, but the polymer is packaged in aluminum plastic, which will not explode but only swell. There are alsos lithium batteries with steel casing and lithium batteries with aluminum casing.
The correct approach to lithium batteries
To summarize, the most important tips for charging and discharging lithium batteries in use are:
< p>1 According to standards. The loading time and schedule must be done even for the first three times;2. When the machine's low battery prompt appears, you should try to start charging as soon as possible; p>3. Activation of the lithium battery does not require special methods. The lithium battery will activate naturally during normal use of the machine. If you insist on using the popular “first three charges and 12 hour activation” method, it will actually not be effective.
Therefore, all practices that consist of performing 12 hours of ultra-long charging and using battseries lithium batteries until they automatically turn off are wrong.
