3.7v 18650 battery pack

　　18650 lithium battery activation:

　　Lithium battery activation does not require special methods, the 18650 Li-Ion will certainly be activated in all normal safety applications. If you stick with the popular first three 12-hour charge-activated modes, at some point, there will be no real results.

　　2. 18650 Li-ion battery can be started with 1865018650 Li-ion battery, 1865018650 Li-ion battery can run at not too high working voltage, otherwise 18650 Li-ion battery can be overcharged.

　　3. The positive and negative electrodes of the battery can be activated several times with a mobile phone charger, and it does not take too long to activate.

　　4. Safe use can be used for charging and discharging power supply or resistance. For safe application, the charge and discharge should be placed at the start-stop level. You can choose to charge and discharge the resistance charge and discharge connection beads for a long time relative to the working voltage until the beads are well damaged immediately.

　　5. Try to charge for one to two hours in a short time, and whether the professional tester has increased the working voltage, if increased, the rechargeable battery can be recharged by selecting a suitable charging head.

　　For the 18650 lithium-ion battery that has not been used safely for a long time, it is impossible to use a digital multimeter to measure the working voltage other than 18650. Many people probably think that the rechargeable battery is broken. In fact, the rechargeable battery is probably not damaged at this time, just sleeping. When the working voltage of the 18650 lithium-ion battery is less than the threshold working voltage of the protection level of the 18650 lithium-ion battery, the working voltage of the 18650 lithium-ion battery will gradually decrease, and it will automatically turn off the switching power supply. At this time, the power of the 18650 lithium-ion battery will enter a sleep state .

　　18650 and economical, 18650 lithium-ion is widely used in various industries, therefore, it is necessary to maintain and maintain 18650 lithium-ion immediately. Tires are the first major event in battery maintenance and maintenance, and the second is to increase the use of 18650 lithium-ion batteries and greatly reduce the damage of 18650 lithium-ion batteries.
