To explore the difference between lithium battery and nickel-metal hydride battery charging

In the use of batteries by many consumers, the use of batteries is often the same concept. Now lithium batteries are already the mainstream, but the previous use of nickel-metal hydrogen batteries is still applied to lithium batteries. In fact, lithium batteries and nickel-metal hydride batteries are not the same in addition to their products.

Newly purchased lithium batteries: the first three times to use the natural shutdown, and then with the original direct charge on the mobile phone to recharge, and then continue to charge for about 1 hour (2000 mAh or more about 2 hours).

Daily: Fill it up and fill it up for more than 1 hour. Avoid late-night charging(high grid voltage). Batteries can be used with charge and can be used for alarm or shutdown. Note that the battery used to shut down is recharged as soon as possible, otherwise the battery self-discharge and the voltage continue to drop may cause the self-lock protection to fail to charge. Make it a habit: go to work during the day, get home at night, start charging, fill up, or pull the plug before going to bed.

Usually used: general lithium batteries can be filled, used, and stopped. Cycle life refers to the number of full charge and full charge, and part of the charge and discharge can be understood as a fraction of a lifetime. Key to battery use: The battery is full and can be recharged for 20 minutes-half an hour to reach saturation, but be sure to avoid long recharging after filling. Continued charging for a long period of time after completion will lead to side reactions. The result is a decrease in capacity and a large internal resistance, a shortened capacity, and a shutdown on the phone. Machines with charge chips such as PPC are best used until no power is recharged, mainly considering the problem of electricity display measurement.

After the battery is filled, charging continues to do great damage to the lithium battery. After charging, the battery will continue to produce side reactions. The number of active substances will decrease, the number of waste substances will increase, the capacity will decrease, and the internal resistance will increase. Severe overcharging will directly destroy the battery structure and cause the battery to be scrapped. Nowadays, some chargers also provide charging protection mode, depending on whether the battery's power is full of adjustment charging mode, can effectively protect the battery.

Lithium-ion batteries can be recharged at any time, and the impact on life is limited. For batteries such as PPC, it is recommended to use automatic shutdown to charge to avoid impact. It can be charged at any time and can be stopped at any time. If it is filled with continuous charging, it will have an impact on the battery life.
