　　I often hear complaints from people that my battery broke or was not durable after only six months, and many consumers have the same experience. Lithium battery manufacturers often see people who remove the battery after buying a laptop without storing it, but when they really want to use it, they can no longer use it. The reason is that they do not understand lithium batteries and do not properly maintain them. If you can do the following, You won't be worried about similar issues:

　　1. Do not allow the first charging time to reach 12 hours

　　When we purchase products with lithium batteries, many salespeople tell us that the first charge of lithium batteries must reach 12 hours. Actually, this statement is not correct. Lithium batteries have been activated before leaving the factory, and the self discharge rate of lithium batteries is very low, so we do not need to charge them for the first time for a long time like regular nickel cadmium/nickel hydrogen batteries. Lithium batteries can be used when fully charged, usually after 3 to 5 complete cycles of charging and discharging (one complete cycle from full to full), the lithium battery can reach a good state.

　　2. Do not use inferior chargers

　　Many friends take great care of their digital treasures but overlook lithium batteries. When choosing a charger, if the original charger cannot be used, it is necessary to choose a brand charger with better quality and overcharge protection function. Poor quality chargers can cause lithium batteries to have a "short lifespan" in light cases, while in heavy cases, they can cause the battery to explode.

　　3. Do not overcharge frequently

　　Long term overcharging can keep the battery in an "excited" high-temperature state, which is detrimental to both lithium batteries and chargers. Therefore, the standard for charging is to fully charge. If the charger does not have overcharging protection function, it is likely to cause a fire or even explosion of the lithium battery.

　　4. Do not touch metal objects

　　The contacts of lithium batteries need to be regularly wiped, but it is important to note that when storing and carrying the battery, the contacts of the battery should not come into contact with metal objects, as this can easily cause a short circuit in the battery and shorten its lifespan.

　　5. Do not frequently use in high or low temperature environments

　　Batteries have their own working and storage environment, and prolonged exposure to high or low temperatures can have a negative impact on the service life and lifespan of lithium batteries.

　　6. Do not use or not charge for a long time

　　If for some reason, our digital devices and lithium batteries at home may be idle for more than 3 months, then we need to regularly charge a certain amount of lithium batteries and then save them (each charging amount accounts for 30% to 70% of the total battery capacity, depending on the storage time and battery capacity).
