18650 lithium battery activation method.
After a period of safe use of 18650 lithium batteries, the rechargeable battery enters sleep mode. At this moment, the capacity does not reach the standard value, and the usage time is significantly shortened. But 18650 lithium batteries are very easy to charge, only requiring 3-5 normal charge and discharge cycles to charge the rechargeable battery. Considering that the characteristics of the 18650 lithium battery itself depend on its basic lack of memory effect, the new 18650 lithium battery in consumers' mobile phones does not require special methods or equipment during the process of activation.
How to activate the sleep mode of
18650 lithium battery
1. Safely use the original charging cable to connect to the power source for charging, and there is no need to use the phone safely during the charging process.
2. Safely use a low-voltage charger to charge the charging battery for 30 minutes, which can be safely charged using a computer USB or power bank.
3. You can try charging quickly for one to two hours, and use a professional technical detector to check if the voltage has increased. If there is an increase, you can choose to continue charging with the original charger, which can activate the 18650 lithium battery.
4. No matter which method is used safely to activate the sleep mode 18650 lithium battery, it cannot be started in a hurry. It is recommended to charge it for half an hour before starting it, and then set the phone to airplane mode.
18650 lithium battery activation method
1. The activation of 1.18650 lithium batteries does not require special methods, and 18650 lithium batteries will naturally activate during normal and safe use. If you insist on using the widely circulated "first three 12 hour long charging talk" method, in a sense, it will not be effective.
2. 18650 lithium batteries can be used to activate mobile phones. The voltage of 18650 lithium batteries does not need to be too high, it can be between 3.3~3.7V, otherwise the charging current of 18650 lithium batteries will be too high
3. Use a portable power bank to connect the positive and negative poles of the battery several times, and the time control does not need to be too long to initiate the call. After initiating the call, the battery can be charged normally with voltage.
4. Safe discharge or resistance discharge methods can be used. The safe use of discharge should be at the level of starting and stopping immediately. Resistance discharge can be achieved by connecting a small electric bead with the corresponding voltage for a long period of time until the small electric bead is connected and immediately extinguished.
5. Try to charge quickly for one to two hours, and use a technical professional tester to check if the voltage has increased. If there is an increase, you can choose to continue charging with the original charger to activate the rechargeable battery.
Advantages of 18650 lithium battery
1. Lithium batteries have a high voltage platform and can be well made into lithium battery packs
High voltage platform for lithium batteries: The average operating voltage of a single battery is 3.7V or 3.2V, which is approximately equal to the series voltage of three nickel cadmium batteries or nickel hydrogen batteries, making it advantageous to combine them into a battery power pack
2. High energy ratio and light weight
Compared to batteries, lithium batteries have higher energy density. Has high energy storage density, currently reaching 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries; Compared to lead-acid batteries, lithium batteries are lighter in weight, with a weight of about 1/5-6 of lead-acid products under the same volume.
3. Long service life and long cycle times
Lithium batteries have a relatively long lifespan, with a lifespan of over six years. Batteries with lithium iron phosphate as the positive electrode can be charged and discharged with 1CDOD and have a record of being used up to a thousand times;
