What are the precautions for the correct use of 18650 lithium-ion batteries?

1. When using 18650 lithium-ion batteries, it is necessary to follow the battery manual. If the 18650 lithium-ion batteries with caps are labeled with voltage capacity, it is necessary to use a dedicated 18650 lithium-ion battery charger for charging. When not in use, the 18650 lithium-ion battery should be isolated, insulated, and protected from short circuits.

2. The correct activation and use of 18650 lithium-ion batteries: For example, before the charger starts charging, a small current is supplied to the battery, and the voltage change of the battery is detected at the same time, and the current is gradually increased until the set value. This process can be regarded as activation or testing charging. The activation of lithium-ion batteries is not a special method, and lithium-ion batteries will naturally activate during normal use of the phone. If you insist on using the first three 12 hour long charging activation methods that have been circulating, it will not actually have any effect.

3. Instructions for correct use and charging of 18650 lithium-ion batteries: Due to the characteristics of lithium-ion batteries, if the battery exceeds the discharge termination voltage during discharge and continues to discharge, it may cause an increase in internal pressure of the battery, damage the reversibility of positive and negative active substances, and significantly reduce or even completely damage the battery capacity; The battery protection board can cut off the circuit and stop over discharging to protect the battery before over discharging occurs. Some electronic adjustment mod circuit boards have protection functions such as overshoot, over discharge, and over current, which have a low dependence on battery protection boards. Mechanical mods hope to mostly choose batteries with protective boards under the best possible conditions. After all, the cost is only about 1 yuan, but the use is very large.

4. 18650 lithium-ion batteries must be equipped with protective plates to limit overcharging, discharging, short circuits, etc., which is beneficial for extending the lifespan and safety of lithium-ion battery packs.

5. 18650 lithium-ion batteries should not be combined with original batteries (such as dry batteries) or other batteries of different capacities, types or brands when used correctly. Do not use batteries that emit odors, heat, discolor or deform, or exhibit abnormalities in any way. If the battery is in use or charging, please unplug it from the device or charger and immediately stop using it.

6. The finished 18650 lithium-ion battery pack should be packaged or transported in boxes. During transportation, it should be prevented from severe vibration, impact, or compression, as well as exposure to sunlight and rain. Vehicles such as cars, trains, ships, airplanes, etc. can be used for transportation, and corresponding transportation reports should be prepared.
