Nowadays, there are more and more electronic products, and lithium-ion polymer batteries, as the main power provider for the operation of these devices, are a very important part. However, as the use time increases, the life of li-polymer batteries is often affected. So how to extend the life of lithium battery as much as possible through reasonable use? AllrunBattery has compiled a series of best practices to protect the life of lithium-ion batteries as long as possible.

What impacts the lithium battery life?
Lithium battery life is related to the number of complete charging cycles, but not directly related to the number of charging cycles. If you want to maximize the effectiveness of lithium-ion batteries, you need to use them frequently to keep the lithium-ion in a flowing state.
Simple understanding, for example, a lithium battery used only half of its power on the first day, and then fully charged it. If the situation persists the next day, that is, use half of the charge and charge it twice in total. This can only be counted as one charging cycle, not two. Therefore, it may usually take several times to complete a cycle. Every time a charging cycle is completed, the power will decrease a bit, but the decrease is very small.
High-quality batteries will still retain 80% of the original power after being charged for many cycles. Many lithium-powered products are still used as usual after two or three years. This is the reason. Of course, the life of the LiPo battery will eventually need to be replaced.
Battery manufacturers take a more conservative estimate, believing that the cycle life of most commercial lithium-ion batteries is between 300 and 500 cycles. Assuming that the power provided by a complete discharge is Q, if the reduction in power after each charging cycle is not considered, the lithium battery can provide or supplement 300Q-500Q of power in its life. From this we know that if you charge 1/2 each time, you can charge 600-1000 times; if you charge 1/3 each time, you can charge 900-1500 times. By analogy, if it is charged randomly, the number of times is variable.
In short, no matter how it is charged, it is constant to add a total of 300Q to 500Q of power. Therefore, we can also understand it this way: the life of a lithium battery is related to the total charge capacity of the battery, and has nothing to do with the number of recharges. Deep discharge and deep charge and shallow discharge and shallow charge have little difference in the impact on the life of the lithium battery.
How to prolong LiPo battery life ?
Five tips on the use of lithium batteries, can help extend the life of lithium-ion batteries, and even prevent fire or explosion.
Remove the battery
Do not leave the battery in the device. Even if the device is turned off, the battery will still have electronic “leakage” problems, which will eventually lead to exhaustion.
The unused battery does not need to be fully charged
For this reason, the drone battery like DJI has a “storage” option. This option can charge or discharge the battery, so that the battery retains only half of its power in order to preserve battery performance for a long time. Fully charged and stored for a long time will greatly shorten the life of the battery.
Avoid overheating the battery
For example, after high-intensity shooting with a digital camera product, the battery may become hot. At this time, do not put the battery into the charger to charge immediately, this will only heat the battery. In addition, do not expose the battery to direct sunlight, and do not place the battery in a place that generates high heat.
Don't leave the battery on the charger for a long time
Many people are used to putting the battery on the charger for a long time, and don’t take the battery out until before shooting. As mentioned before, when the battery is not in use, only about 50% of the power should be retained. Fully charge the battery one or two days before use, and remove the battery immediately after it is fully charged.
Avoid the power drop to zero
Although the current regular battery products have a protection circuit, there is still a chance that the voltage will drop too low due to long-term discharge. For most people, it is almost impossible for a lithium battery with a low voltage to recover to its original voltage safely. Even if there are corresponding equipment and methods that can safely restore the voltage to normal levels, they may no longer be able to store electricity.
