In addition, in some machines, charging more than a certain time, if not remove the charger, this time not only to stop charging system, will start to discharge - charge cycle. This is perhaps the manufacturer has its own purpose, it is clear that in terms of battery life is bad. At the same time, long charging would take a long time, often need at night, and to China's power grid situation, at night in many parts of the voltage is higher, but also volatile. As already said, the lithium battery is very delicate, than nickel in the electric charge and discharge aspects of fluctuations in the capacity of resistance is much less, so this brings additional risk. In addition, another aspect can not be ignored is the lithium battery is also not suitable for over-discharge, over-discharge of lithium batteries is also very unfavorable. This leads to the following questions. Have to buy your favorite camera for consumers, facing the top big thing is the digital camera charging problem. After all, the battery life and power is what everyone wanted. I believe many consumers are on the "first three charging more than 12 hours to be full of" memories, then this statement really correct? Steps / Methods 1. First we look at the course of development in recent years the battery. The cost of high to low battery is lithium-ion batteries, nickel metal hydride batteries, nickel-cadmium batteries. Nickel-metal hydride and nickel cadmium batteries each section is 1.2V, lithium-ion battery is about 3.7V per session. Nickel-metal hydride and nickel cadmium rechargeable performance, as is the nickel-cadmium nickel-metal hydride generation product, and environmental protection, free of heavy metals cadmium. Some recommend charging the battery when the body has long The original digital devices (including mobile phones, camera batteries) are used in nickel metal hydride (cadmium) batteries, the battery low cost, easy to use, but the disadvantage will produce a small amount of memory effect. The subsequent introduction of the lithium-ion battery is completely overcome this shortcoming, there is no memory effect of the charging process to make it more casual and longer life.
