Correct charging method for ternary lithium-ion batteries
Method 1: Before leaving the factory, lithium-ion batteries are activated and pre-charged. Therefore, ternary lithium-ion batteries all have residual power. Lithium-ion batteries are charged according to the adjustment period, which requires 3 to 5 complete charge and discharge cycles.
Method 2: Before charging, do not intentionally discharge lithium-ion batteries, as improper discharge can damage them. When charging, use slow charging as much as possible and minimize fast charging; do not charge for more than 24 hours. The internal chemical substances of the battery will only be fully activated and reach optimal performance after three to five complete charge-discharge cycles.
Method 3: Please use original or reputable brand chargers. Lithium-ion batteries must be charged with lithium-ion battery-specific chargers and the instructions must be followed. Otherwise, the battery may be damaged or even dangerous.
Method 4: For newly purchased ternary lithium-ion batteries, the first 3-5 charges are generally called the adjustment period, and they should be charged for more than 14 hours to ensure sufficient activation of lithium-ion activity. Lithium-ion batteries do not have a memory effect, but they have strong inertia. Sufficient activation is necessary to ensure optimal performance in future use.
Method 5: Ternary lithium-ion batteries must be charged with a dedicated charger; otherwise, they may not reach full charge, affecting their performance. After charging is complete, do not leave them on the charger for more than 12 hours. When not in use for an extended period, the battery should be separated from the portable electronic device.
Maintenance
If the battery is not used for a long time, it is best to charge it to about 40% and store it at a temperature of 10~30℃, and recharge it about every six months.
Lithium-ion batteries have extremely strict requirements on the current and voltage applied during charging and discharging. To protect the battery from damage due to abnormal external electrical environments, a chip managing the battery's state is installed inside the battery. This chip also records and calibrates the battery capacity. Nowadays, even counterfeit mobile phone batteries don't skimp on this crucial protection chip; otherwise, they wouldn't last long.
The memory effect is a common phenomenon in nickel-metal hydride (NiMH) rechargeable batteries. In detail, it means that if the battery is used without being fully charged for a long period, its capacity will noticeably decrease, and it will be difficult to fully charge it later. Therefore, the key to maintaining NiMH batteries is to only recharge them when they are completely drained and to only use them when fully charged. The memory effect in commonly used lithium-ion batteries is negligible.
