Precautions for charging lithium-ion batteries
① Prevent overheating during charging
If the temperature of a lithium-ion battery exceeds the specified operating temperature (35°C) during charging, the battery capacity will continuously decrease, meaning the power supply time when fully charged will be shortened. This will damage the battery quality and reduce its lifespan.
②Prevent the charging temperature from getting too low
If the battery is charged in a low-temperature environment (below 4°C), the battery capacity will continue to decrease, and it may even fail to charge. However, the situation is different from that in a high-temperature environment. It is not a permanent damage. When the temperature rises to a suitable level, the battery capacity will return to its previous state.
③ Frequently used
Frequent use keeps electrons in a constant state of flux within the lithium-ion battery, which helps extend its lifespan. If you don't use it frequently, remember to complete a full charge cycle for the lithium-ion battery each month, i.e., perform a deep discharge and deep charge once a month.
④ 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.
⑤ Preventing frequent use of lithium-ion batteries is arguably the most fundamental method. Even if you usually use external power and it seems like you're not using batteries, the aging process of batteries is actually ongoing over time.
