Experts tell you the correct use of lithium batteries - — Circulation charge and discharge is a less a life?

Cycle is to use, we are in the use of batteries, are concerned about the use of the time, in order to measure the rechargeable battery can use how long such a performance, it specifies the definition of cycles. The actual user use, for there is no comparable conditions of different test, is necessary to compare the standard definition of cycle life. National standard, a specified cycle life of lithium ion battery test conditions and requirements: under the condition of room temperature 25 degrees to 1 c by way of constant current constant voltage charging system of charging 150 minutes, with constant current discharge to 2 1 c discharge system. 75 v cutoff for a loop. When there is a discharge time is less than 36 minutes at a time when the test over, cycle number must be greater than 300 times. Explanation: A. This definition specifies the cycle life test is deep deep filling way to B. Specifies the cycle life according to this model after execution must be more than 300 times since capacity there is still more than 60%, in fact, different cycles of the circulation system is very different, such as more than the other conditions unchanged, only 4. The constant pressure of 2 v instead of 4. The constant pressure of 1 v voltage battery cycle life test for the same model, so that the battery is not deep filling method, the final test number of cycle life can be improved by almost 60%. So if the cut-off voltage up to 3. 9 v test, the cycles should be able to increase several times. The less about cycle time is a life that has many friends are discussed, I'm just complementary explain, we are talking about cycles cannot be ignored when circulation conditions, despite the rules about cycling times is it doesn't make any sense, because cycles is a means of detecting battery life, rather than a purpose! Myth: many people like to use mobile phone lithium ion battery in automatic shutdown recharging. This is unnecessary. In fact, the user can't according to the national standard test patterns to use batteries, does not have a mobile phone can be in 2. 75 v to shut down, and the discharge mode is not electricity, large current constant exile but GSM pulse discharge peace of small discharge current hybrid approach. Another kind of measure method of cycle life, is time. Some experts put forward general civil lithium ion battery life is 2 ~ 3 years, combining with the actual situation, for instance, with 60% of the capacity of the termination of life, and lithium ion battery aging effect ( Reference point 9) , cycle life is expressed by the time I think is more reasonable. Lead battery charging mechanism is similar to the lithium ion battery, is the current limiting pressure limiting way, using the way is shallow shallow, filling his life expression is time, there is no number, such as 10 years. So for lithium ion batteries, it is not necessary to use shutdown rechargeable, lithium ion battery is suitable for use at any time the charging manner use, it is also one of his biggest advantage for nickel metal hydride batteries, please use this feature. Lithium-ion batteries, electric vehicles, lithium battery manufacturer, storage battery manufacturer scooter battery manufacturers, product by the supervision and inspection institute of guangdong province, through international CE certification, by the ping an insurance company of China national group, two years warranty, the first in the New Year.
