The number of battery cycles refers to the number of times a battery completes a complete charging and discharging process, which is an important indicator of battery life and performance. Different types of batteries have different definitions and calculations of the number of cycles.
Here are some common battery types and how many cycles they count::
1. Lithium battery
Lithium battery is a battery widely used in mobile phones, laptops, electric vehicles and other equipment, it has the advantages of high energy density, low self-discharge, no memory effect and so on.
The number of cycles of lithium battery refers to the process of the battery from full charge to running out, that is, when the battery uses 100% of the battery capacity, a charging cycle is completed, that is, a cycle.
However, this does not mean that the battery has to be used up every time it is charged, in fact, shallow charging and shallow discharge can help extend the life of the lithium battery. For example, if you use 75% of the battery one day, then fully charge the device overnight, and use another 25% the next day, the total discharge will reach 100%, thus completing a charging cycle in two days, which is a cycle.
Generally speaking, the number of cycles of lithium batteries is between 300-1000 times, and when the number of cycles exceeds this range, the capacity and performance of the battery will decrease significantly.
2. NiMH battery
NiMH battery is a kind of battery commonly used in digital cameras, flashlights, toys and other equipment, it has the advantages of low cost, high safety, environmental protection and so on.
The number of cycles of a NiMH battery refers to the process of the battery from full charge to full discharge, that is, when the voltage of the battery drops to 1When it is below 0V, a charging cycle is completed, that is, a cycle.
However, NiMH batteries have a memory effect, that is, if the battery is charged without being fully discharged, the effective capacity of the battery will be reduced, therefore, NiMH batteries need to be deeply discharged at regular intervals to eliminate the memory effect.
Generally speaking, the number of cycles of NiMH batteries is between 500-1000 times, and when the number of cycles exceeds this range, the capacity and performance of the battery will decrease significantly.
3. Lead-acid batteries
Lead-acid battery is a kind of battery commonly used in automobiles, motorcycles, electric bicycles and other equipment, it has the advantages of maturity, stability, and cheapness.
The number of cycles of a lead-acid battery refers to the process by which the battery goes from full charge to full discharge, that is, when the voltage of the battery drops to 10When it is below 5V, a charging cycle is completed, that is, a cycle.
However, there is a vulcanization phenomenon in lead-acid batteries, that is, if the battery is in a low power state for a long time, it will cause a chemical reaction between the lead plate inside the battery and the sulfuric acid to form lead sulfate that is difficult to dissolve, thereby reducing the capacity and performance of the battery, therefore, the lead-acid battery needs to be charged regularly to prevent vulcanization.
Generally speaking, the number of cycles of lead-acid batteries is between 200-500 times, and when the number of cycles exceeds this range, the capacity and performance of the battery will decrease significantly. To check the number of cycles of a lead-acid battery, you can use some professional chargers or instruments, such as smart chargers, battery testers, etc., or check directly on the battery.
