How long can one cycle be used for different loads?


Nowadays, the transition from traditional lead-acid batteries to lithium iron phosphate (LiFePO4) batteries is revolutionizing the industry. Designed for different applications, LiFePO4 batteries offer unparalleled performance, reliability, and longevity.
In this aera of information explosion, filled with a wide range of commodities, lithium batteries are no exception, each brand has its own strengths, that each brand mentioned the battery cycle times of 4,000 ~ 5,000 times what exactly is referred to?

What is battery cycle time?

The number of battery cycles is an indicator used to measure whether the battery needs to be replaced, here we have to correct a misunderstanding: the number of battery cycles is not equal to the number of times it has been charged. The so-called battery cycle times, that is, a complete charge/discharge cycle, so the cycle times is actually a charging cycle of a way to calculate, when the battery reaches a complete charging cycle, the battery cycle times will be +1, and the number of charging times, that is, the battery is completed every charge, the number of charging times will be +1.
Here is an example will be easier to understand: a battery, it now has 100% of the power, you once it runs out to 0%, and then recharge to 100%, this is a charge and discharge cycle. That's one charge/discharge cycle. At this point, the battery has been cycled once, and charged once.
However, a battery, which now has a 100% charge, you use it up to 40% the first time, then charge it to 100%, then use it up to 60% the second time, then charge it to 100%. These two uses, combined, are also a complete charge/discharge cycle. At this point the battery is cycled once, but charged twice.

Battery Models

First of all, a cliché topic: the advantages of lithium iron phosphate battery. Undoubtedly, the use of high-tech, as a new type of lithium battery, has the advantages of long life, large capacity, good safety and so on. Of course, how to deal with waste batteries is always distressing, but this battery truly realizes the whole process of pollution-free production, use and disposal, and therefore lithium iron phosphate batteries have become the first choice for a variety of use scenarios.
The batteries mentioned here are not suitable for remote control, children's toys, Bluetooth mouse, etc., but more for RV, home energy storage, marine, solar off-grid system and other use scenarios.
At present, SANFOU sells LFP battery models 12V 6Ah, 12V 50Ah, 12V 100Ah, 12V 200Ah, 24V 100Ah, and the upcoming models are 12V 300Ah, 12V 100Ah UpGrade. If you have a need for batteries, then after reading this article, you will be able to better choose for your needs! If you have a need for batteries, then after reading this article, you will be able to choose the right battery model for your needs.

Loads and their powers

Load means a device that consumes electrical energy and converts it into mechanical energy, heat, light, etc. A load is an electrical appliance, such as a light, lamp, furnace, motor, refrigerator, air conditioner, etc.
When we want to choose suitable batteries for these loads, we should pay attention to whether the batteries can meet the requirements for the use of electrical appliances, and here are a few points to pay attention to:

Voltage compatibility: Make sure the battery voltage matches or can be properly converted to match the voltage requirements of the appliances.
12.8V batteries can directly power appliances designed for 12V systems.
25.6V batteries may require a voltage converter to power appliances designed for 12V or 24V systems.

Power: Check that the batteries have enough power to power the appliance for a reasonable period of time. Calculate the power consumption of each appliance and compare it to the battery level to ensure that it will meet the power requirements.
Also consider the start-up surge or peak power requirements of some appliances (e.g. coffee makers), which may exceed their rated power consumption.

Ideal usage time

Once we have determined that the battery is suitable for the appliance, we can calculate how long different types of batteries can be used for different loads, in this case, when the battery is adapted to the appliance and under ideal discharge conditions.
Battery energy is measured in watt-hours, and we know the power of the appliance (W): Time(hours)=Wh/W. Of course, this calculation also needs to take into account the actual use of the appliance, whether it can reach the rated power, the appliance's operating temperature and so on. For example, if 12.8V 100Ah is used for 150W refrigerator, the ideal usage time is 8.5hrs.
In this way, you can choose the right LiFePO4 battery according to your needs!


Choose the right type of battery to meet the needs of your appliances, to give your life full of electricity, understand the appliances you use, according to the relevant parameters can be calculated to find out the length of time you are looking for, SANFOU provides you with a variety of battery choices to meet your needs for electricity.
