What is the general voltage of the headphones?

The charger voltage generally used for single cell lithium batteries is about 5V, so the charger is normal.

If the lithium battery comes with a protection board, there may be a problem with the circuit of the protection board and the output and input of the lithium battery will not work.

SIf the lithium battery is not turned on properly when using the charger alone, it may be because the main circuit detects abnormal voltage.

The lithium battery with its own protection plate is fully charged at about 4.2V. Once fully charged, it automatically stops charging, like the operation of a mobile phone battery.

How much battery should a Bluetooth headset have?

Headphones are divided into two categories: high impedance and low impedance! Audio headphones are mostly low impedance (less than 8 ohms!) The audio driver of this type of headphones The voltage does not exceed 1 volt at most!

High impedance headphones are mainly used in detection and special instruments! They are also used in old-fashioned communications equipment! Impedance is usually a few hundred to thousandsohms! The output voltage varies from a few volts to tens of volts!

The battery of the Bluetooth headset is a lithium battery

Precautions for using the battery:

1. The battery is the most charged. It is best not to store the battery at full capacity, because at that time the battery is highly polarized and the electrodes are in an unstable state under high voltage and are more prone to redox reactions, leading to self-discharge resulting in an irreversible loss of capacity. The best storage voltage is 3.8-3.9V. The best long-term storage voltage of the battery is 3.6-3.9V. It is recommended to charge and discharge once every six months. After charging, discharge the battery to approximately 3.8 before storing.

2. The self-discharge rate of lithium batteries at room temperature is approximately 2% to 3% per month. WhenIf stored at temperatures above 55°C, the self-discharge rate will reach 10% per month. Therefore, long-term storage of batteries requires taking into account the temperature factor.

3. Be careful not to pack the battery in an anti-static bag to avoid the formation of conductors or semiconductors that can cause excessive battery discharge. If the excessive discharge exceeds the specified value, the battery will suffer structural damage, accompanied by gas, and the battery will swell.

The battery model of the i12 Bluetooth headset is LP602040 lithium battery. The basic battery parameters of the i12 Bluetooth headset are rated voltage 3.7V, rated capacity 450mAh, length 42mm, width 20.5mm, thickness 6.3mm, the length of the wire 50 mm and the weight 9 g.
