3.7V Lithium Polymer Battery

　　Do lithium batteries have a memory effect?

　　At present, there are no new companies in my country that focus on the power lithium battery electrolyte sales market. Most of the lithium battery electrolyte sales market is concentrated in the small lithium battery industry. In addition, we should pay attention to the fact that most lithium battery electrolyte companies in my country have adopted the strategic direction of "exchanging price for volume", which is an unsustainable development trend. In recent years, the distribution of lithium-ion battery electrolytes around the world has been undergoing changes and turbulent adjustments, and this development trend will be maintained in the next few years.

　　Lithium batteries have no memory effect. Battery memory effect means that if the battery is a nickel-cadmium battery, if it is not fully charged or discharged for a long time, it will easily be marked in the battery and reduce the battery capacity.

　　The battery memory effect means that the battery seems to remember the user's daily charging and discharging range and pattern. It becomes difficult to change this pattern over time, and it can no longer charge or discharge to a large extent. This effect does not exist with lithium-ion batteries.

　　1. Battery cycle life

　　The battery charging cycle time indicates the process of using up all the power of the rechargeable battery from full to empty, and then from empty to full. This does not mean charging once. For example, a lithium-ion battery uses half of its charge for a few days and then is fully charged. If it is still the same the next day, charge it after half use, and charge it twice in total. This is only one charging cycle, not two.

　　Therefore, battery charging may take several rounds to complete a cycle. Each time a charging cycle is completed, the battery capacity will be reduced a little. However, this reduction is very small for high-quality rechargeable batteries after a few cycles. It will still retain 80% of its original capacity, and many lithium-ion battery-powered products are still in use two or three years later. Of course, lithium-ion batteries must be replaced after useful ones arrive.

　　2. Notes on the use of lithium batteries:

　　1. When riding in rain or snow, the charging and discharging plug between the lithium battery pack and the electric vehicle must not come into contact with water. Turn off the battery power switch when not needed to avoid the adverse effects of short circuit faults. Minimize the use of bottle carts in extreme natural environments. Be careful with lithium-ion batteries.

　　2. Rechargeable batteries should be placed to avoid water, fire, keep dry and dry, and prevent obvious vibration, collision and short circuit failure. In summer, rechargeable batteries should be protected from direct solar radiation.

　　3. In particular, there is no need to disassemble, change or destroy rechargeable batteries privately; it is prohibited to use rechargeable batteries in other well-known brands or battery-powered vehicle models; to prevent short-circuit failure of the battery charging port.
