What are the reasons that affect the life of the Bluetooth headset charging pin?
Overcharge and overdischarge, the normal operating voltage range of lithium battery is between 3.6V and 4.2V. Use below 3.6V or above 4.2V (the charger usually needs 5V, after passing the current limiting circuit and the battery's own load, the voltage will become lower than 4.2V) charging will cause the battery to heat up and affect its service life. However, current batteries have an overcharge protection circuit, as long as they are not too copycat chargers, there is usually no problem.
2. Large current and short circuit, long-term continuous use, if you often talk or listen to music for a long time, the battery will heat up too much current, and long-term use will affect its normal service life, so it is best not to frequently Use it for a long time, even if you stop using it for a few minutes. This will also be better for battery performance.
3. Low battery for a long time. If the battery is not used for a long time, let the battery stay at a voltage below 3.6V, or use too much to discharge the battery until the battery is damaged. Many batteries are damaged or the use time after charging increases The shorter is mostly because of this reason.
