Many people are unsure of how to properly charge and discharge new lithium batteries after purchasing them. So, what are the precautions for the first charge of a lithium battery? Here are the correct methods to follow.
In our daily lives, what we commonly refer to as lithium batteries are also known as lithium-ion batteries. These batteries are developed using the active chemical properties of lithium metal. The charging and discharging process of the battery is essentially an electron transfer process, which is a redox (reduction-oxidation) reaction. Therefore, unlike nickel-metal hydride batteries, lithium batteries do not have a memory effect, so you don’t have to worry about reduced battery capacity due to incomplete charging. However, due to the active nature of lithium metal, it can easily be affected by the environment. There are some issues we need to pay attention to when using lithium batteries.
Proper Use of New Lithium Batteries
When using lithium batteries, note that after being idle for a period of time, the battery will enter a dormant state, with capacity lower than normal and shortened battery life. However, lithium batteries are easy to activate. After 3-5 normal charge and discharge cycles, the battery can be activated and restore its normal capacity. Due to the inherent characteristics of lithium batteries, they have virtually no memory effect.
Therefore, during the activation process of a new lithium battery in your phone, no special methods or equipment are needed. Not only is this theoretically true, but from my practical experience, it’s best to adopt the standard charging method from the beginning, i.e., the "natural activation" method.
Lithium batteries are activated before leaving the factory, but they still need a second activation after leaving the factory. It is recommended to carry out 3-5 complete charge and discharge cycles when first using the battery, which is very beneficial for battery life. Lithium batteries are highly susceptible to environmental temperature, and the charging temperature should ideally be maintained between 25-40 degrees Celsius. Charging in low or high temperatures can damage the battery.
The safe operating voltage range for lithium batteries is 2.8-4.2V. Temperatures outside this range can make the lithium ions in the battery very unstable, potentially causing accidents. To ensure the battery remains within a safe range, a dedicated charger must be used. These chargers will automatically adjust the charging method based on the current state of the battery.
Generally, different lithium battery manufacturers have specific requirements for chargers, so do not randomly change chargers if unsure.
How to Properly Use a Lithium Battery for the First Time
The first charge of a new mobile phone lithium battery does not require any special method. It can be determined based on the actual power level. If the power is below 20%, it is recommended to charge before use. If the power is above 20%, you can wait until the power drops to 20% before charging. Disconnect the charger after the battery is fully charged.
Lithium-ion batteries do not have the memory effect of nickel-cadmium batteries and are activated before leaving the factory, so they can be charged at any time and be on standby in daily use. However, to fully extend battery life, pay attention to the following issues when charging:
- Ensure that the device is running the latest version of the operating system, as new systems usually contain more advanced energy-saving technologies.
- Avoid charging in environments with temperatures above 35°C, as the battery capacity may be permanently damaged. Storing the battery in high-temperature environments may also cause irreparable damage.
- It’s best to remove the phone case during charging to prevent extra heat generation due to the case.
- If the phone will not be used for a long time, do not fully charge or discharge it. Keep the power at around 50%, turn off the power switch, and store it in a cool, dry place.
Lithium batteries are consumables with a fixed lifespan. Therefore, mastering the correct usage methods is the key to extending battery life.
The above outlines the correct methods for the first charge and proper usage of lithium batteries. If you are unsure of how to use a lithium battery, try the methods in the tutorial as soon as possible. I hope this helps everyone.
