How to double the service life of the 18650 lithium battery

　　1. Lithium batteries are afraid of cold and heat. Do not use them in a hot environment. In summer, many people prefer to expose lithium battery electric vehicles to the sun, or in winter, they are also parked in the yard or on the main road. This is very detrimental to the service life of lithium batteries. The migration rate of lithium ions in the electrolyte and battery film is closely related to temperature. In fact, the temperature between -20℃-55℃ may be misused. In daily life, the use of temperature between 5℃-35℃ is not harmful to lithium batteries. Users in the north take the lithium batteries back to their homes and store them as much as possible in winter, and do not put them outdoors. In the south, the migration rate of lithium ions in the electrolyte and battery film is closely related to temperature. In fact, the temperature between -20℃-55℃ may be misused. In daily life, the use of temperature between 5℃-35℃ is not harmful to lithium batteries. Users in the north should store the lithium batteries at home as much as possible in winter, and do not put them outdoors. Users avoid summer exposure.  

　　2. Lithium batteries should not be deeply charged and discharged frequently. Many people think that the number of reincarnations of lithium batteries in the manual of electric vehicles is that they can only be plugged and unplugged once, even if they are used once. This is actually a misunderstanding. The manual actually refers to the number of complete re-discharges. Lithium batteries are different from nickel-cadmium batteries. Lithium batteries have no memory effect and can be charged anytime, anywhere. Charging when the battery has excess power will not shorten the service life, and the battery can be nurtured and its cycle of reincarnation and utilization can be extended. For lithium batteries, the correct approach is slow charging instead of deep charging.
