###Extend lifespan and ensure safety: The ultimate maintenance guide for your lithium battery**

From smartphones to laptops, from electric cars to drones, lithium batteries have become the driving force of modern life. It is powerful, lightweight, and rechargeable, but at the same time, it is also somewhat "delicate". Proper maintenance not only significantly extends the lifespan of batteries, but also ensures their safe use.

By mastering the following knowledge, you can become a "health expert" for your own device battery.

####* * Core principle: Understand the "preferences" of lithium batteries**

Lithium batteries do not have the "memory effect" like ancient nickel cadmium batteries. Their biggest fear is "pressure" - mainly from voltage and temperature pressure. All of our maintenance activities revolve around how to alleviate its pressure.

####Daily use article: How to "use" it well? **

**1. Avoid extreme charging and discharging, maintain "shallow charging and shallow discharging"**

*The Golden Rule: Keep the battery level between 20% and 80% as much as possible. This is the lowest pressure and most comfortable state range for lithium batteries.

** * Avoid over discharging: * * Try not to use the battery to automatically shut down and recharge at 0%. Deep discharge can cause irreversible damage to the internal structure of the battery.

** * No need to deliberately fully charge: * * No need to charge to 100% every time. Long term exposure to 100% high voltage will accelerate the chemical aging of batteries. Most devices offer an "optimized battery charging" function, which learns from your habits and suspends charging after reaching 80% until it is fully charged before use.

**2. Avoid playing while charging (especially for high-performance applications)**

*When you play large games or run heavy software while charging, the battery will be in a high voltage state of "charging" and "discharging" at the same time, generating a large amount of heat. **Heat is the number one killer of lithium batteries.

*If conditions permit, especially when performing high-intensity tasks, it is best to plug in the power source and * * remove the battery * * (if detachable) or allow the device to bypass the battery and directly take power. This is particularly important for gaming laptops and high-performance computers.

**3. Timely unplug the power to avoid long-term full charge**

*Laptops, tablets, and other devices that are plugged in for a long time at 100% power will cause sustained "high voltage stress" on the battery, leading to rapid capacity decay.

*If long-term plug-in use is required, it is recommended that most devices be charged to around 80% and then unplugged. Many brands of computers, such as Lenovo, Dell, and Apple, offer "battery protection mode" or "charging threshold" settings in their management software, which can limit the maximum charging capacity to 50% -60%, making them ideal for long-term desktop use.

####Charging Habits: How to Charge Properly? **

**1. Use original or certified chargers**

*Poor quality chargers may cause unstable voltage, excessive charging current, serious damage to battery life, and even lead to safety issues. Please make sure to use original or officially certified (such as MFi, CE, UL) charging equipment and data cables.

**2. Charge as needed, fragmented charging is fine**

*Lithium batteries have no memory effect, and 'charge as you go' is healthier than 'recharge after use'. Using scattered time to replenish the device's battery, such as charging it when the battery level drops to 40%, is very beneficial for the battery.

**3. Fast charging is good, but don't rely on it**

*Fast charging technology is achieved by increasing power, inevitably generating more heat. It is understandable to use fast charging when in urgent need, but when not in a hurry in daily life, using a standard charger is a milder and more beneficial choice for the long-term health of the battery.

####Environment and Storage: How to "Store" Safely? **

**1. Strictly guard - high temperature! **

*It is absolutely prohibited to place devices (such as mobile phones, spare batteries) in high-temperature environments such as enclosed cars with direct sunlight or near heating. High temperatures can directly and permanently damage batteries and pose significant safety risks.

*When charging, it is the heating period of the device. Please ensure that the device is placed in a well ventilated place and not wrapped in thick blankets or placed on the sofa for charging.

**2. Long term storage requires attention to detail**

*If the device needs to be idle for more than a month, do not fully fill or completely empty it.

*Best Storage Capacity: Charge the battery to around 40% -60%, then turn it off and store it in a cool, dry place. At this battery level, the chemical state of the battery is the most stable, which can minimize aging to the greatest extent possible.

**Summary: "Three musts and three don'ts" for lithium battery maintenance**

** * Keep the battery level between 20% and 80%.

*Charge and use in a cool and ventilated environment.

*Use the original charger and charge it as needed.

*Do not keep the battery in a 100% fully charged state for a long time.

*Do not expose the device to high temperatures.

*Do not frequently use extremely low battery levels (0%) before recharging.

By following these simple guidelines, your lithium battery can provide you with more durable and safe power services over a longer lifespan. Take care of your device, starting with caring for its' heart '.
