How to choose high -quality 18650 lithium batteries.portable energy storage battery power supply price

release time:2023-04-12 Hits: Popular:AG11 battery

　　 9V USB 1.5V 1000mWh

　　Choose a 18650 lithium battery that is suitable for you, such as: appropriate brand, suitable voltage, suitable capacity, continuous discharge, battery service life, and higher security. Next, we will make a specific explanation one by one:

　　1. The rated power

　　The amount of electricity at 18650 is related to the battery life. It is represented by "MAH" that the greater the capacity, the longer the battery life.

　　2. Continuous discharge (CDR)

　　The continuous discharge capacity is expressed in C, and the number of continuous discharge current = the amount of continuous discharge power C multiplied by the capacity.

　　For example, the 18650 battery can provide 2800 mAh power and can be released 0.5 W continuously. If the continuous discharge time exceeds 1.4 A, the service life of the battery will decrease, and even the risk of combustion and explosion.

　　3. Internal resistance

　　Internal resistance is the resistance of the battery itself. The lower the internal resistance, the lower the power consumption, the larger the battery capacity, and the internal resistance in the introduction of the battery. Therefore, you must pay attention when you buy it. 100 mΩ battery cells.

　　Multi -festival 18650 series batteries must purchase the same model of the same brand, otherwise a large internal resistance and low capacity battery will be a disadvantage.

　　4. Temperature

　　Temperature has a great impact on the life of the 18650 lithium battery. The higher the temperature, the greater the damage to the battery.
