There are a few precautions when using a 26650 lithium-ion battery. This type of battery is the largest type and is used in a wide variety of electronic devices. This battery has a nominal voltage of 3.6 or 3.7 volts per cell and can deliver up to 20-30 Amps. The battery’s maximum charge voltage is 4.2 V, so be sure to use a charger that can handle this voltage range.

1. Prevent charging at too low temperature

If the lithium battery is used in a low temperature environment, that is, below 4C, the use time of the 26650 lithium ion battery will also be reduced, and the original lithium battery of some mobile phones cannot even be charged in a low temperature environment. But don’t worry too much, this is only a temporary situation, different from the use in a high temperature environment, once the temperature rises, the molecules in the battery are heated and immediately return to the previous power level.

2. Prevent charging at high temperature

If the 26650 lithium-ion battery is used in an environment higher than the specified operating temperature, that is, above 35C, the battery’s power will continue to decrease, that is, the battery’s power supply time will not be as long as usual. If the device is charged at such a temperature, the damage to the battery will be even greater. Even if the battery is stored in a hot environment, it will inevitably cause corresponding damage to the quality of the battery. Therefore, trying to maintain a suitable operating temperature is a good way to extend the life of lithium batteries.

3. Frequent use

Life is movement. In order to maximize the performance of the 26650 lithium-ion battery, it is necessary to use it frequently so that the electrons in the lithium battery are always in a state of flow. If the lithium battery is not used frequently, please remember to complete a charging cycle for the lithium battery every month and do a power calibration, that is, a deep discharge and deep charge.

26650 lithium-ion batteries are now mainly used to replace traditional nickel-chromium and nickel-metal hydride batteries, and are used in mining lamps, flashlights, power tools, toys, instruments, rear switching power supplies, communication equipment, medical equipment and their military lighting industries. Compared with nickel-chromium and nickel-metal hydride batteries, its advantages are reflected in the following aspects:

1. High energy density and low self-discharge rate.

The capacity of the 26650 lithium battery is twice that of the nih rechargeable battery of the same quality. In addition, the internal resistance of the 26650 lithium battery in my country is less than 60m, which greatly reduces the self-consumption of the rechargeable battery and can improve the use time of the rechargeable battery.

2. Stable charge and discharge characteristics of the battery.

The 26650 lithium battery has no memory, is insoluble when heated, has a high safety factor and has a long service life.

3. High working voltage.

The working voltage of 26650 lithium battery is generally higher than that of nickel-chromium alloy and nickel-metal hydride rechargeable batteries.

4. 18650 lithium-ion battery pack can be used in series.

5. Zero pollution of environmental protection.

The Li-Ion 26650 can often be recharged, charged and discharged with specific Li-Ion battery exercises. That is, when the rechargeable battery is charged, the lithium-ion battery is converted into a specific lithium-ion battery. The negative material management system is high-purity graphite, which is a layered structure of carbon, which has many microplates, and when the lithium-ion battery moves to the negative battery, it is placed in the microplate and embedded in the microplate The more lithium-ion batteries you have, the higher the battery charge capacity.

Similarly, when charging and discharging the battery, the lithium-ion battery slides down the negative carbon layer and moves to a positive level. The more the lithium-ion battery returns to the positive level, the higher the charge and discharge capacity. Generally refers to the 26650 lithium battery capacity, that is, the charge and discharge capacity.
