　　What are the characteristics of energy storage batteries and how to extend their life?

　　The characteristics of energy storage batteries are that they can be used in a wide range and have relatively low maintenance costs, which can reduce the overall investment. In addition, try not to charge the battery for more than 12 hours, and try to use a dedicated charger. Next, I will introduce the details to you.

　　1. Various characteristics of energy storage batteries

　　1. The temperature range used is relatively wide, and it is generally required to operate normally in a temperature environment of -30-60 degrees.

　　2. The battery has better low-temperature performance and can be used even in areas with relatively low temperatures.

　　3. The capacity consistency is good, and the consistency is maintained when the batteries are used in series and parallel.

　　4. Good charging acceptance ability. In unstable charging environment, it has stronger charging acceptance ability.

　　5. Long life, reducing repair and maintenance costs, and reducing overall system investment.

　　2. Methods to extend the life of energy storage batteries

　　1. Do not charge for more than 12 hours.

　　It is best to charge according to standard time and standard methods, especially do not charge for more than 12 hours. Usually, the charging method described in the mobile phone manual is the standard charging method suitable for the mobile phone.

　　2. Place the energy storage battery in a cool place

　　High states of charge and increased temperatures will accelerate the loss of battery capacity. If possible, try to charge the battery to 40% and place it in a cool place. This allows the battery's own protection circuitry to operate over a long shelf life.

　　If the battery is exposed to high temperatures after being fully charged, it will cause great damage to the battery. (So when we use a fixed power supply, the battery is fully charged and the temperature is generally between 25-30°C, which will damage the battery and cause its capacity to decrease).

　　Do not expose the battery to high temperatures or severe cold. For example, in the dog days of summer, you should not place your phone under the sun to withstand the scorching sun; or take it to an air-conditioned room and place it in a place where the air conditioner blows directly.

　　3. Avoid recharging after the battery is completely used up.

　　The life of the battery depends on the number of repeated charges and discharges. The energy storage battery can be continuously charged and discharged about 500 times. After that, the performance of the battery will be greatly weakened. You should try to avoid discharging all the remaining power in the battery and then recharging it. Otherwise, as the number of charges increases, If it increases, the battery performance will gradually weaken, and the battery's standby time will hardly decrease.

　　4. Use a dedicated charger

　　Energy storage batteries must use special chargers, otherwise they may not reach saturation and affect their performance. After charging, avoid leaving it on the charger for more than 12 hours, and separate the battery from the phone when not in use for a long time. It is best to use chargers from the original manufacturer or from a reputable brand.
