The correct way to charge a lithium-ion battery
Lithium-ion batteries have high energy density and high average output voltage. They have low self-discharge, below 10% per month, and no memory effect. They have a wide operating temperature range of -20℃ to 60℃. They exhibit excellent cycle performance, can be charged and discharged quickly with a charging efficiency of up to 100%, and have high output power. They have a long lifespan. They are environmentally friendly and are known as green batteries.
Using the correct charging method, lithium-ion batteries can be fully charged. If the charging method is incorrect, the lithium-ion battery may be undercharged, or even suffer from reduced capacity, shortened lifespan, or overcharging.
Method 1: Before leaving the factory, lithium-ion batteries undergo activation and pre-charging, so they 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 the lithium-ion battery, as improper discharge can damage it. When charging, use slow charging as much as possible and minimize fast charging; do not charge for more than 24 hours. The battery's internal chemicals will only be fully activated and reach optimal performance after three to five complete charge-discharge cycles.
Method 3: Please use the original manufacturer's or a reputable brand charger. Lithium-ion batteries must be charged with a dedicated lithium-ion battery charger and the instructions must be followed. Otherwise, the battery may be damaged or even dangerous.
Method 4: If the newly purchased battery is lithium-ion, the first 3-5 charges are generally called the adjustment period, and it should be charged for more than 14 hours to ensure that the activity of lithium ions is fully activated. Lithium-ion batteries do not have a memory effect, but they have strong inertia. They should be fully activated to ensure that they can achieve the best performance in future use.
Method 5: Lithium-ion batteries must be charged with a dedicated charger; otherwise, they may not reach full charge, affecting their performance. After charging is complete, avoid leaving the battery on the charger for more than 12 hours. When not in use for extended periods, the battery should be separated from the portable electronic device.
