At present, Bluetooth speaker is very popular in the market. Its appearance design is exquisite, mainly single speaker, in order to increase the corresponding Bluetooth function, answer the phone and so on. For such a good product, if we want to use it for a longer time, we should cherish and maintain its batteries, we need to know. Some of the basic principles of batteries, as well as some common sense of first charging and regular charging, the following music angel musci Angel summarizes some content, hoping to help readers and friends.
1. It takes 2-3 hours for a Bluetooth audio to be charged for the first time. A fully charged Bluetooth speaker can last 9 to 10 hours.
2. Shut down and charge when charging. One is good for the battery of Bluetooth speaker and the other is fast charging.
3. Generally speaking, the red light means charging while the green light means full. If the red light is always on (charging more than 3-5 hours), it indicates that there is a problem with the charging circuit of your speaker, or that it does not have full-power self-stop function at all. Don't overtime if charging for 1 hour can work properly.
4. If Bluetooth audio is using lithium batteries, we should be clear that lithium batteries have almost no memory effect and can be used with charge, but they may not reach very good capacity in the previous several times. Generally, they will be normal after three normal charges and discharges.
5. There is a protective circuit inside the lithium battery, which can protect the battery from over-charging and over-discharging. It also supports high-current charging and can be charged quickly. Usually charging can be done only when the green light is on, but it is easy to damage the protection circuit if it is overcharged.
6. Also, it is clear that the nominal capacity of Bluetooth audio batteries, such as 700MAH, requires an hour of charging time for each 100MAH under 200 mA fast charging current, and 700MAH takes about 7 hours to charge. By analogy, if it is 1300MAH charging battery, it takes 13 hours to charge.
7. Don't use Bluetooth audio when charging. If you must use it, it will cause some damage to the battery of Bluetooth audio. The damage value depends on the value of Bluetooth audio and your knowledge of electrical appliances. Normally, the battery in the speaker can be replaced.
