1. Take all your batteries and use them after temperature treatment. The battery will greatly shorten the use time when the temperature is unstable, because the battery is not charged and a considerable part of the lithium ions have been used for memory. This method can make a part of the memory power release, winter is over, put it outside for a while, then go to the house.
2, There is a way to remove the battery, put it for about a week, the electricity will be slowly consumed, you need to use the machine to completely consume the electricity. Then fully charge, it is estimated that your current charging time must be very short.After the full, disconnected and rushed, repeated several times, absolutely effective.
The 18650 battery life theory is cyclic charging 1000 times. Due to the large capacity per unit density, most of them are used in laptop batteries. In addition, the stability of the 18650 is very good at work. It is widely used in various electronic fields: it is often used in high-end glare flashlights. Power, wireless data transmitters, electric warm clothing, shoes, portable instrumentation, portable lighting equipment, portable printers, industrial equipment, medical equipment, etc.
The 18650 means 18 mm in diameter and 65 mm in length. The model number of the No. 5 battery is 14,500, 14 mm in diameter and 50 mm in length. Generally, the 18650 battery is used in the industry, and there are few civilians. The common ones are used in laptop batteries and high-end flashlights.
The 18650 is just the size of the battery. It can be divided according to the type of battery. 18650 for lithium ion, 18650 for lithium iron phosphate, 18650 for nickel hydrogen (rare), and the common 18650 is lithium ion.
