Proper use of 18650 lithium batteries and precautions.

Proper use of 18650 lithium batteries and precautions.,The working environment of 18650 lithium batteries :
Battery charging temperature: 10 ℃~45 ℃
Battery discharge temperature: 0 ℃~45 ℃
Storage for 30 days: -10 ℃ to 45 ℃
Storage for 90 days: -10 ℃~35 ℃

Pay attention to using insulation structure measures between the battery cell (exposed aluminum layer on the side and pole ear sealing edge packaging film fracture position) and the protective plate, as well as between the battery cell and the electrical appliance: special attention should be paid to avoiding the hidden danger of contact between the packaging film aluminum layer and the positive and negative electrodes (including the live parts of the electrical appliance), otherwise it may cause liquid leakage and gas expansion.

18650 lithium batteries  stored for more than 6 months should be charged and discharged in a timely manner for one week, and then recharged to 3.7-3.9V.
When children use batteries, it is necessary to teach them according to the user manual and closely monitor them to ensure correct use of the battery.

If the battery leaks and the electrolyte gets on the skin or clothing, immediately clean the affected area with running water, otherwise it may cause skin inflammation

Read the device manual for the battery and correctly install and remove the polymer lithium battery.
If the device is not used for a long time, remove the battery and place it in a cool, dry place, otherwise the battery may rust or deteriorate in performance.
If the terminals of polymer lithium batteries become dirty, wipe them clean with a dry cloth before use. Otherwise, the battery will have poor contact, causing energy loss or inability to charge.
