The correct way to charge lithium batteries

The mobile phone battery is a lithium battery, which can be disconnected if it is not fully charged, as long as the power can maintain normal use. “Eat less often” and “charge as you use” are the best charging methods for lithium battery life.

Do not wait until the battery is exhausted before charging; excessive discharge of the mobile phone will have a certain impact on the mobile phone. In severe cases, this can cause a breakdown. The cell phone does not turn on normally, so try to indicate the battery level on the cell phone. Charge in time when the battery is too low;

Use the original charger. and data cable to charge the phone: non-original chargers may encounter various problems, damage the battery and reduce its lifespan.urea of ​​life. Lifespan;

Try not to use your cellphone while charging: Playing with your cellphone while charging can easily consume the battery and shorten its service life;

After charging is completed, please unplug the power supply in time;

The battery is a consumable and as the number of charging times increases, the actual capacity of the battery decreases.

Five 3.6V lithium batteries18650can be equipped with a charger when combined into an 18-piece battery V. A single battery is 3.6V. , fully charged The measured value after charging is 4.2V, and the measured value after connecting all 5 cells is about 21V.

If you want to load completeBasically, you need a charger with an output voltage of 22V. As for the output current of the charger, it depends on the capacity of a single battery. The 5 battery combination is fully charged at about 21V, but it doesn't take long after being connected to charge, because the laptop uses an external 19V power supply, and the battery reaches 18V after being used for a while and cannot be used. .

Advantages of lithium batteries:

1. The energy ratio is relatively high. It has a high storage energy density, currently reaching 460-600 Wh/kg, approximately 6-7 times that of lead-acid batteries.

2. Long service life, service life can reach more than 6 years. The battery with lithium iron phosphate as the positive electrode can be charged and discharged with 1CDOD, and there is a record that it can be charged and discharged.used 10,000 times.

3. The rated voltage is high (the operating voltage of a single unit is 3.7V or 3.2V), which is approximately equal to the series voltage of three nickel-cadmium or nickel-cadmium rechargeable batteries. metal hydride. , which makes it easier to form a battery power supply.
