Do cell phone lithium batteries need to be fully discharged once a month?

1. What is said on the Internet that the battery cannot be completely exhausted is correct, because it means that the battery itself cannot be completely exhausted. However, cell phones usually have protection circuits. When the battery is almost empty, it protects itself and turns off automatically. Even though it turns off automatically, it is not completely exhausted. >

2. Charge fully the first three times. There is basically no need to talk about discharge, because the current production of lithium batteries basically has a formation process, which means that it has been activated.

3. Lithium batteries do not have a memory effect, which means that the capacity of the battery itself will not decrease due to half-way use for a long time. So use it as you wish. There is no need to completely load and unloadt once a month.

Can a lithium battery scooter be recharged after exhausting a power grid

According to the figures provided by the poster, the charging voltage and current can be calculated to have a power of 6000 watts. In this case, a load can be 6 kWh. Because one kilowatt hour of electricity is equal to 1,000 watts multiplied by 1 hour. If it can be fully charged in an hour, then it has 6 kilowatt hours of electricity. If you want to calculate over several hours, multiply by 6 degrees per hour.

How to use lithium batteries correctly

Yes.

Typically, lithium batteries can be charged more than 1,000 times. Do not leave the battery in a saturated state for a long time. When fully charged, unplug the power immediately; when exhausted, as this will seriously damage the battery and affect its service life.

Storage method

1. Primary lithium battery

Also called primary lithium battery. It can be discharged continuously or intermittently. Once the energy is exhausted, it can no longer be used, and it is widely used in low-power electronic products, such as cameras. Primary lithium batteries have a very low self-discharge and can be stored for 3 years. The effect will be better if stored in refrigerated conditions. It is a good idea to store primary lithium batteries in a low temperature location. Note: Primary lithium batteries are different from lithium-ion batteries, cannot be charged, and charging is very dangerous!

2. Lithium-ion battery

Also called secondary lithium battery. It can be stored for more than six months at 20°C because its self-discharge rate is very low and most ofits capacity can be restored.

Lithium batteries have a self-discharge phenomenon. If the battery voltage is stored below 3.6V for a long time, the battery will overdischarge and damage the internal structure of the battery, thereby reducing the battery capacity. life. Therefore, lithium batteries stored for a long time should be recharged every 3 to 6 months, that is, charged to a voltage of 3.8 to 3.9 V (the optimal storage voltage of batteries lithium is approximately 3.85 V) and maintained at a depth of discharge of 40% to 60%, should not be full. Batteries should be stored in a dry environment between 4°C and 35°C or in moisture-proof packaging. Keep away from heat sources and do not expose to direct sunlight.

Lithium batteries have a wide application temperature range. They can still be used outdoorsur during the northern winter, but their capacity will be significantly reduced if they return to room temperature, the capacity can be restored.

The first three timesAfter charging, recharge it until it is fully charged. Then you can charge normally.

The correct way to use lithium batteries 1. Lithium-ion batteries have a lifespan. When you want to buy a battery, remember to look at the production date of the lithium-ion battery. Of course, the newer the better. Because your lithium-ion battery starts to “die” as soon as it leaves the factory. The lifespan of a lithium-ion battery depends on many factors. In a best-case scenario, your lithium-ion battery will lose 20% of its maximum charge capacity within a year of leaving the factory.

Proper use of lithium batteries 2. Do not let your device discharge.

Remember that a char cyclege “one” means if you use 50% of the battery on the first day, charge it at night and use it again at 50% the next day. It's a cycle.

Charging a lithium-ion battery repeatedly without interruption will not reduce battery life.

The correct way to use lithium batteries 3. Lithium-ion batteries will not be overcharged when charging. They have internal circuit protection. The biggest fear of lithium-ion batteries is the problem of excessive temperature, overshooting. The 40 degree temperature reduces the amount of energy a lithium-ion battery can hold.
