Battery manufacturers teach you the correct way to use lithium-ion batteries. The correct use of lithium-ion batteries can be broadly categorized into three aspects: proper charging, proper discharging, and proper maintenance. Regardless of the electronic product in which a lithium-ion battery is used, its fundamental properties remain largely unchanged. Paying close attention when using lithium-ion batteries can not only protect them but also minimize unnecessary damage.
Battery manufacturers teach you the correct way to use lithium-ion batteries.
①The normal charge-discharge cycle of a lithium-ion battery is approximately 500 to 800 times. Lithium-ion batteries that have reached the end of their lifespan must be recycled and disposed of in accordance with local laws.
② Do not let the device run completely out of power. If the lithium-ion battery is too low, it may be permanently damaged. Therefore, plug it in to charge whenever convenient.
③ Some people claim that lithium-ion batteries should be fully charged for 12 hours on their first charge, but this is not the case. In fact, doing so will affect the lifespan of lithium-ion batteries.
④ The optimal charging environment for lithium-ion batteries is 25 degrees Celsius. If the temperature is too low, the charging speed of lithium-ion batteries will be relatively slow, while if the temperature is too high, it will affect the quality of lithium-ion batteries.
⑤ Lithium-ion batteries do not have a memory effect, so when charging, you should not deliberately discharge the battery. Just let it run out of power naturally. Excessive discharge will damage the battery life.
⑥ It should be noted that lithium-ion batteries are very susceptible to the influence of ambient temperature. It is best to keep the charging temperature between 25-40 degrees Celsius. Charging at low or high temperatures will damage the battery.
Correct charging method for mobile phone lithium-ion batteries
1. Charge when needed. Under normal circumstances, mobile phones and laptops will remind you when the battery is low. At this time, you should charge it in time. Although low battery will not cause a direct safety accident, excessive use will damage the structure of lithium-ion batteries over time.
2. Charge until fully charged. Lithium-ion batteries cannot be overcharged; they have internal circuitry for protection. The biggest problem with lithium-ion batteries is overheating; temperatures exceeding 40 degrees Celsius will reduce the amount of charge a lithium-ion battery can hold.
3. Avoid multitasking. I have personal experience with this: when using your phone while charging, especially while playing games, it's very easy for the phone to get hot. The reason is simple: the phone is essentially doing two jobs at the same time, forcing it to exert twice the effort, which naturally causes it to heat up.
Correct use of lithium-ion batteries in electric vehicles
Lithium-ion batteries for electric vehicles are typically manufactured in a half-charged state. It's best to fully charge the battery before the first ride, firstly because self-discharge reduces the battery's charge capacity, and secondly because it activates the active materials within the battery.
Use the original lithium-ion battery charger whenever possible, as original chargers have strong compatibility and a suitable charging rate.
Performing a deep discharge on a battery periodically can also help "activate" the battery and slightly increase its capacity. The general method is to periodically perform a complete discharge on the battery.
When not in use, lithium-ion batteries for electric vehicles should be stored in a cool, ventilated place, away from high temperatures and humidity. Avoid riding in the rain as much as possible; if you must ride, take precautions to prevent water from entering the battery. Do not strike, puncture, step on, modify, or expose the battery to direct sunlight. Do not place the battery in environments with microwaves or high voltage.
