The 18650 3.7V battery can be used in the wireless microphone receiver for 8 hours. The voltage of 18650 lithium battery is 3.7V and it is 4.2V when fully charged. The main battery capacity is 1800 mAh to 2600 mAh. It is generally believed that when the no-load voltage of a lithium battery is below 3.0 V, it is considered exhausted. However, when discharging most lithium batteries, the no-load voltage cannot be lowered below 3.2V, otherwise excessive discharge will damage the battery.
General configuration of an 18650 battery:
The nominal voltage of a single cell is generally: 3.6 V or 3.7 V< /p>
The charging voltage is generally: 4.20 V (lithium cobalt oxide is 4.2 V to 4.3 V)
The minimum end voltage discharge is generally: 2.75 V. A voltage lower than this voltage canut easily cause significant battery drain. capacity or even scrapped
Maximum charging termination voltage: 4.20 V
Diameter: 18±0.2 mm
Height: 65± 2.0mm
Capacity: Above 1000mAh, conventional capacity is 2200mAh to 3200mAh, LG has the highest 18650 battery capacity, which can reach 3600mAh mAh, but the price is not low.

18650 battery parameters?
Standard voltage 3.7V. According to relevant public information requests, LG high-rate batteries are ionic batteries. The standard voltage of lithium-ion batteries is 3.7V, the charging cut-off voltage is 3.6V, and the capacity is 1200mAh to 3350mAh. LG 41865 battery cell is a type of 18650 specification battery. It is a standard lithium-ion battery model defined by the company.Japanese company Sony Corporation in order to reduce costs.
What are the parameters of 18650 lithium battery?
18650 is the creator of lithium-ion batteries - a standard lithium-ion battery model defined by the Japanese company SONY in order to reduce costs. 18 means the diameter is 18mm and 65 means the length is 65mm. .0 represents a cylindrical battery.
The nominal voltage of a single cell is generally: 3.6 V or 3.7 V
The charging voltage is generally: 4.20 V (the oxide of lithium-cobalt is 4.2 V to 4.3 V)< p>The minimum end-of-discharge voltage is generally: 2.75 V. A voltage lower than this voltage can easily result in a significant decrease in the capacity of the battery, or even its disposal.
