When purchasing an outdoor power supply, do you know how long the outdoor power supply lasts? How many years can the outdoor power supply be used for? How to calculate the battery life of the outdoor power supply? Will it be scrapped when the number of times marked is reached? Do you use the calculation cycle while charging?
Typical life for a portable outdoor power supply is approximately 500 to 2500 charging cycles. The number of cycles is the unit used to indicate the life of the outdoor power supply, charging + discharging counts as one cycle. That is to say, if the life of an outdoor power supply is 800 times, then when the power is charged from 0% to 100% and the power is used up at 0%, the life span is about 800 times. The life of the portable power supply is expressed in the number of cycles, because the standard life of the same model varies depending on the conditions of use and the environment.
How to enlarge the service life of outdoor energy storage power supply and make it longer?
In the case of infrequent use, it is necessary to maintain regular charging, and do not let the power supply be in a state of power loss for a long time to cause the battery to age and affect the life; for frequent use, keep shallow charging and shallow discharge. Shallow charging means not charging too much when charging, reaching 90 When the power is less than 20%, you can stop charging; shallow discharge means that you don’t wait for the power to run out before charging, and you can charge when the power is lower than 20%-30%. At the same time, don't overcharge for a long time or run out of electricity to affect the battery life.
