Lithium battery use precautions and routine maintenance

1. Lithium-ion battery charging precautions.

Lithium-ion batteries are strictly forbidden to be charged from the discharge terminal, and must be charged from the charging socket with a special charger. When the charging indicator lever on the charger stops rolling, please unplug the charging plug in time to avoid overcharging the battery.

2. Discharge precautions.

Lithium-ion battery pack has over-current protection function. When the use current of the electrical equipment exceeds the maximum output current of the product, the overcurrent protection circuit operates and the electrical equipment seems not to work normally.

3. Precautions for daily use.

The output of the discharge terminal is not controlled by the switch on the panel, and the output of the discharge terminal will be turned off only when the battery voltage is lower than 9.0V. The switch on the panel controls the output of the display and the USB socket. When the switch is on and the battery voltage is 9.1V, the display flashes on and off at a frequency of one second to remind you to charge in time. When the battery voltage is 9.0V, the display goes off and the USB socket turns off the output to protect the Li-ion battery from over-discharging. Although there is an output short-circuit protection function, but it is not suitable for frequent short-circuit in daily use.

4. Notes on recycling.

The normal cycle charge and discharge times of lithium-ion batteries is about 500 ~ 800 times, lithium-ion batteries at the end of their service life should be recycled and disposed of in accordance with local laws.

5. Lithium-ion battery use environment and maintenance methods.

The charging temperature of lithium-ion batteries is 0 ~ 45, and the discharge temperature is -20 ~ 60.

Should be in a clean, dry and ventilated environment and should be protected from contact with corrosive substances and away from fire and heat sources.

Li-ion battery pack has no memory effect and can be charged as needed, but it should be noted that Li-ion battery cannot be over discharged, which will cause great capacity loss.

Do not mix the battery with metal objects to avoid metal objects touching the positive and negative terminals of the battery, causing a short circuit and damaging the battery, or even causing danger.

Avoid frequent overcharging, which will cause the internal temperature of the battery to rise to a very high level, which is harmful to both the Li-ion battery and the charger. So, one full charge is enough to turn your lithium-ion battery into a small bomb.

To sum up: the battery is a consumable, it has a certain service life (the number of charge and discharge is usually 300-500 times), so mastering the correct use is the secret to extend the life of the battery.

6. Correct use of lithium-ion battery pack battery maintenance.

Charging: The safe working voltage range of lithium batteries is 2.8 ~ 4.2V, below or above this voltage range of lithium ions in the battery becomes very unstable, or even cause accidents. To ensure that the battery is within the safe range, a special charger is required.

Lithium-ion batteries need to be charged and discharged every three months to restore their original performance.

Before using lithium-ion batteries, it is necessary to check whether they meet the load requirements. If they do not meet the load requirements or are used at high currents (more than 1C), the batteries will be damaged or have a shortened service life.
