4、 Constant voltage charging: This method is similar to the previous one. Constant voltage is actually a limit voltage, setting a relatively accurate high voltage, and then charging it to that voltage. If you don't promise to continue charging, the Jianghu people call it foolish charging. If this charger makes the cut-off voltage very accurate, it is safer on the low side. If it is too high, it still needs to rely on a protective board. As for bare batteries, it's a blessing in disguise. Commonly seen in today's mobile phone full charge and flashlight direct charge, this type of charger costs less than a yuan and is made entirely of inferior parts. The retail prices on Taobao vary from to, and it's hard to say how long it will last.

The current 3.7V 18650 lithium-ion battery has a general cycle life of around 500-1000 cycles, while the 3.2V 18650 has a general life of over 2000 cycles. Of course, the prerequisite is that qualified batteries produced by legitimate manufacturers have a short lifespan if they are defective or counterfeit.

Basic structure of 18650 lithium-ion batteries

The lifespan of a 18650 lithium battery is generally 300-500 charging cycles. Assuming that the electricity supplied by a complete discharge is Q, without considering the decrease in electricity after each charging cycle, a lithium battery can supply or supplement a total of 300Q-500Q of electricity during its lifespan. From this, we can understand that if you charge with 1/2 each time, you can charge 600-1000 times; If 1/3 of the charge is used each time, it can be charged 900-1500 times. By analogy, if randomly charged, the number of times is uncertain.

In short, no matter how it is charged, the total amount of electricity replenished is between 300Q and 500Q, which is constant. So, we can also understand it this way: the lifespan of lithium-ion batteries is related to the total charging capacity of the battery, and is not related to the number of charges. The impact of deep charging and shallow charging on the lifespan of lithium batteries is not significantly different.
