　　How to choose high-quality energy storage batteries and how to extend their service life?

　　If we want to judge whether it is a high-quality product when selecting an energy storage battery, we can identify it by checking the appearance and packaging, comparing weight, detecting live operation, etc. We can also test the internal resistance and maximum current to see if it is relatively stable. Just a good battery. Then I will introduce the relevant content to you in detail.

　　1. How to choose high-quality energy storage batteries

　　1. Check the appearance and packaging

　　The quality of a battery can first be judged from its appearance and packaging. A product that cannot even detail the packaging is definitely not a professional product. Appearance can help us filter out some inferior products.

　　2. Compare weight

　　The weight and capacity of energy storage batteries are directly proportional. If it is a polymer energy storage battery, if the weight difference is too big, the capacity will definitely be insufficient. However, some batteries have different capacities. In addition, you can also feel from the outer packaging whether the weight of the battery is relatively heavy. If it is heavy, it will tend to be a high-quality energy storage battery.

　　3. Test internal resistance and maximum current

　　In fact, the fastest way to judge the performance of energy storage batteries is to test the internal resistance and maximum discharge current. A good quality energy storage battery has very small internal resistance and a large maximum discharge current. Use a multimeter with a 20A range and directly short-circuit the two electrodes of the energy storage battery. The current should generally be around 10A, or even higher, and can be maintained for a period of time. A relatively stable battery is a good battery.

　　4. Detection of live work

　　During the charging process of the energy storage battery, if the battery poles do not get hot after continuous discharge for about 10 minutes, it proves that the battery protection board system is complete. Generally, the quality of energy storage batteries with high-quality protection boards is better than ordinary energy storage batteries.

　　2. How 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 state of charge and increased temperature will accelerate the decline 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 charging the battery after it 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 a reputable brand.
