Lithium batteries are almost the most common type of batteries in our daily life, widely used in cell phones, computers, and electric cars and other daily necessities. Do you know the service life of a lithium battery? Or want to find out the specific factors affecting the service life, in this article I will give you a detailed information.
How Long Can a 3.7V Lithium-Ion Cell Use After One Time Charge
In general, the running time of a Li-ion battery is usually determined by the capacity and the operating device. Specifically, a battery can last approximately 2 to 10 hours after per charge. Take a 3.7V battery with a capacity of 2000mAh for example, it can last approximately 5-10 hours in a low-power device.
What Is The Shelf Life Of Lithium Batteries?
You can know the shelf life of lithium batteries by looking at their packaging. The life is worked out and determined by makers according to properties of natural science for chemical, physics and the characteristics of a particular cell.
These times often correspond to the production date, or manufacture date, of the battery. Nowadays there are many such times one can find stamped or printed on shelves and wrappers alike-including battery expiration dates: from about five years actually put into use for one can (three given at time of production); up to 20, depending upon type and handling in storage underground This is different for each battery type, and storage conditions will also have an impact on how long it can safely be used.
The Factors May Affect The Using Term
Generally speaking, the cycle life of 3.7v Li-ion batteries from regular manufacturers is 500-1000 cycles, the specific length of use is determined by different factors during the use process, which includes the charging cycle, application equipment, temperature, depth of discharge, frequency and intensity of use, and storage conditions and so on, all of them is the thing you need to notice when using.
Charge Cycle
A charge cycle is the process by which a battery completes a full cycle of discharging and recharging. Typically, a 3.7V lithium-ion battery can undergo 300 to 500 charge cycles before its capacity begins to drop. Some high quality batteries can even reach 1,000 charge cycles.
This process also affects the life of the battery. Proper charging cycles can maintain good battery performance, while incorrect charging cycles and charging habits, especially the overcharging and over discharging situation, can damage your battery and reduce its life, so proper charging cycles are necessary to ensure the normal use of your battery.
Application Equipment
The lifespan of a Li-ion battery is equally relevant to the device it is being used in, which is usually determined by the power consumption of the device, with higher-powered devices such as smartphones or drones generally draining the battery faster than lower-powered devices such as remote controls or flashlights. The power management system of different devices also affects how long the battery lasts on a charge.
Operating Temperature
Operating temperatures can also seriously affect battery life. For example, higher temperatures can accelerate chemical reactions within the battery, which can lead to a decrease in performance, and can also trigger thermal runaway, ultimately leading to battery failure. Conversely, extremely low temperatures slow down these reactions, reducing the efficiency and performance of the battery.
That’s why it’s best if you don’t use lithium batteries in extreme environments.
For example, you are better not to place the battery in direct sunlight conditions in the summer, and try not to place it outdoors in cold weather in the winter, and try to place it in temperatures between -20°C and 55°C.
Depth of Discharge
Depth of discharge is how much capacity the battery has used before recharging. Frequently discharging your battery to very low levels (close to 0%) will shorten its life. Typically, it is more beneficial to keep the charge level between 20% and 80% to maximize the life of your battery.
Mode of Use
How often and how intensively a battery is used can also affect its life. High-drain applications can quickly consume large amounts of power, which can shorten the overall life of the battery. Regular, moderate use is better for battery health.
How To Prolong The Using Life?
Store Properly
Good battery storage is essential if you want to maintain healthy battery lifetime. Fully charged or discharged batteries can lead to permanent damage to your battery cells. The optimum level for storage is around 50% of capacity, where it would remain totally cool and dry to protect against any reduction in battery performance.
To prevent moisture and damage a result from corrosion or short-circuit, it is better to keep a pile of batteries in a dry place.
Use Regularly
The long periods of non-use can also a decline in battery performance as time passes by, so you’ll want to avoid idling your battery and use and charge it regularly to maintain its health and prevent loss of capacity.
Avoid Complete Discharge
During use you should try to avoid charging the battery when it is fully depleted, this is usually detrimental to the performance of the battery, partial discharging seems to be a better practice, means that charging the battery before it has been used up to 20% of its capacity is more conducive to prolonging the life of the battery and helps to reduce the strain on the battery cells.
Keep Cool
You should maintain your battery at an appropriate temperature, too high a temperature not only indicates the high voltage that the battery is carrying, but also raises concerns that it could explode at any time. The best measure is to store and use the battery in a cool environment and avoid exposing it to high temperatures, especially during charging.
Use a Suitable Charger
If you want to keep your battery working well, you had better make sure you use a charger that is up to snuff. Most of the time, a matching charging device will be given to you by the manufacturer, this device is called the original charger in the industry at large.
When you do not have the original charger around, it is best to use a 3.7V lithium-ion battery examiner charger. An incompatible charger is most likely to cause overcharging or undercharging of the battery, and that will also make a shortened battery life.
Conclusion
The above is a lithium battery length of use and the factors that determine the length of use, I hope that after reading this you will have a general understanding and in the day-to-day proper use and preservation of your battery, so that it can maximize the performance, rather than waste.
