Keeping Your Lithium Batteries Happy: A Simple Guide
So, lithium-ion batteries are in pretty much everything we use daily. Wanna keep them running their best for as long as possible? It's all about how you treat them. This is a simple guide on getting the most life out of them, based on expert advice and scientific research.
1.Charging
Charging: It should be fully charged when using the product for the first time because there will be self-discharge that will reduce the power in the lithium battery and activate the active substances in it. Afterward, while using the product, charge it in time whenever the power is lower than 20% to avoid harm done to the battery life by over-discharging. Also, at any time, even if there is 50% power before charging, it is effective to charge the lithium battery.
Overcharging: Unplug the charger after charging immediately to avoid long-term overcharging.
Choose an appropriate charger: Use the original or compatible charger, and pay attention to the use of the charger to avoid using inferior charger. The current of the charger is too large, it can destroy the lithium battery protection system, will cause a short circuit, thus causing a fatal accident of the lithium battery.
Be aware of the charging temperature: charge in The environment is not too high temperature and too low temperature environment.The best charging environment temperature is room temperature.
2. Discharging
Overdischarging: Lithium batteries are most afraid of overdischarging. The discharge power should not exceed 80% of the battery capacity. When the discharge voltage is less than a certain value, it may result in the battery being scrapped. But the mobile phone lithium battery has within it a protection circuit. So, if the voltage isn't low enough to damage the battery, then the protection circuit shall work and stop discharging.
High-power discharge should be avoided: As the discharge of the lithium battery increases, the voltage sag decreases more rapidly and reaches the cutoff voltage much earlier, but the decay rate in the final stage drops, so it is in this stage that better characteristics low-rate discharge has over high-rate discharge. Try not to discharge at high power.
3. Storage
Optimal temperature: The most appropriate storage state for lithium batteries is 50% storage, between 40% and 60% of the battery's nominal capacity. Choose the storage temperature between 4℃ and 35℃. Never allow the battery to experience high temperatures or be subjected to freezing conditions. Both lithium batteries production and life is affected by high temperatures. Charge and discharge periodically: If unused for the next few months, it is advisable to recharge and discharge every few months to keep it active. Storage conditions need to be considered: Lithium batteries must be stored in locations that are dry and cool, away from moisture. Also, the storage area should protect lithium batteries against impact, dropping, squeezing, or disassembly that can damage the battery's internal structure and result in compromised performance and safety.
