Experts tell you the correct way to use lithium batteries

Experts tell you the correct way to use lithium batteries. Recently, I found an article about batteries and shared it with my friends. Although the important focus of this article is cell phone batteries, most digital cameras now use lithium batteries, which work on the same principle as cell phone batteries. Therefore, reading this article is still very practical. 1. Know the memory effect 2. Do you want to activate the battery 3. Is it necessary to make up for the first three hours 4. Whether the rechargeable battery is in the best condition 5. The greater the charging current, the faster the charging speed, is this true? 6. Is the output current of the direct charging sign equal to the charging current? 7. Is the cycle charge and discharge life short? 8. The larger the battery capacity, the better 9. Can you store the full battery? 10. Can the green light of the seat charger last an extra hour? 11. The seat Is the charging rate full? 1. Know the recall effect (the first discussion is nickel-cadmium batteries and nickel-metal hydride batteries, but if you are not interested, you can skip them and go directly to the second type) The battery recall effect refers to the reversible battery Failure, that is, the battery can be recovered from the beginning after failure. The recall effect means that the battery has experienced a specific working cycle for a long time and actively maintains this specific working tendency. This is first of all in the meaning of nickel-cadmium batteries. Nickel-cadmium bagged batteries have no recall effect, while sintered batteries have a recall effect. Ni-MH batteries are not subject to this meaning. Due to the advancement of modern nickel-cadmium battery technology, remember that the effect has been greatly reduced, and another phenomenon to replace this meaning, the grid of nickel-based batteries, under normal circumstances, nickel-cadmium batteries caused by these two effects, nickel-hydrogen batteries Just because of the effect of the dot matrix recall, and the effect of the small nickel-cadmium battery. In practice, the way to eliminate the recall effect is to formulate strict specifications and operating procedures. Improper operation will promote the growth of plants. Regarding nickel-cadmium batteries, the normal protection is punctual deep discharge: uniform use of monthly (or 30 times cycle) for deep discharge (discharge to 1.0V/day, foreigners call it sports), always use photovoltaic cells or use Ways to ease back to turn off formation and other purposes, but this is not a movement, because you don’t use tools (such as mobile phones) at 1.0V/turn it off every day, you need special equipment or complete the work, but many nickel-metal hydride battery chargers have this function. Regarding nickel-cadmium batteries that have not exercised for a long time, due to the accumulation of recall effects, they will not be able to use exercise for capacity recovery and require deeper discharge (repair). This is a process of discharging the battery to 0.4v for a long time with a small current, and requires professional equipment. Regarding nickel-metal hydride batteries, the frequency of exercise every three months or so can effectively alleviate the recall effect. Since the cycle life of Ni-MH batteries is much lower than that of Ni-Cd batteries, this repair method is not used. ▲Claim 1: Do not charge the battery in advance, and it is harmful because the battery life is unnecessarily reduced. ▲Claim 2: It is not recommended to use a resistor to connect the positive and negative poles of the battery for discharge. The current cannot be controlled. Simply put in 0V, and even cause the polarity of the battery to rotate in series.
