Can You Overcharge a Bluetooth Headset?

Bluetooth headset battery charging time and overcharging is not a concept. Overcharge means that the voltage is higher than the charge cut-off voltage during charging, and the general lithium battery is 4.2V. The voltage determines whether the battery is overcharged and has nothing to do with how much time to charge. But the consumers will take too long to charge as an overcharge.

After charging the Bluetooth headset

After the Bluetooth headset is fully charged, a prompt will be given on the headset or charger, such as the change of the indicator color or the indicator light is off. Most of the electronic products currently on the market use of lithium batteries. The batteries have been activated at the factory, and the lithium batteries have no memory, so they can be used as needed. When the display battery is full, you can turn off the power (you can charge another 1-2 hours after the first three times).

Charging voltage

Generally, due to the battery management chip in the charger or Bluetooth headset, the highest output voltage to the positive and negative terminals of the battery is 4.2V. Even if it is over, there is a protective board built into the lithium battery. This means that the voltage to the cell will never exceed 4.2V. It will not be overcharged for a long time. There is a large Bluetooth headset that can be safely charged, so doing so will not damage the Bluetooth headset battery.

Use of charger

But be careful not to plug in the charger for too long, such as two days a day. If it is too long, the charger will also be charged. Secondly, the Bluetooth headset will cut off the power, so the battery will be used. This may start charging again, then fill it up, then use it again, although the shallower The charge and discharge have little effect on the life of the lithium battery, it has always been to reduce the service life.

Lithium battery overcharging is terrible, and the damage is considered to be good luck. If it is serious, it may explode. The charging explosion in the previous news is the flaw of the design product. The space explosion on the lithium battery is caused by the explosion. Under normal circumstances, the polymer lithium battery will only bulge, leak, and will not explode. It’s okay to charge so many people around, and from another side, the Bluetooth headset battery will hardly overcharge.

Bluetooth headset battery charging tips

1. Do not over-discharge

When the device prompts “The battery is low”, it should be charged; until the device is automatically turned off, it will be charged, and the battery has been over-discharged. This can affect battery life. So when the Bluetooth headset indicates low battery, you can charge.

2. Do not overcharge

When the charger is full, you should unplug the charger. Nowadays, the charger generally has a design that is full of self-stopping. It is no problem to remove the battery from the charger for a short time, but the battery is left on the charger for a long time, and the voltage of the grid rises late at night, the charger that has stopped charging. After the voltage rises, it will continue to charge, causing the battery to be overcharged. This can affect battery life.

3. Keep the battery

If the battery is not used for a long time, it should be charged to 60%, stored separately in a cool and dry place, and recharged every 4 or 5 months.

4. Standby charging

It is recommended not to use the Bluetooth headset when charging, standby charging.

Proper use of the battery will ensure battery life. The Bluetooth headset battery is double-protected. The adapter has a protection board. The battery has a protection board. When it exceeds the minimum voltage of the protection board, it stops discharging. The charging principle is the same. Basically, there will be no problem with overcharge and over-discharge. If the Bluetooth headset battery is really overcharged, you can’t charge it. So feel free to use your Bluetooth headset.
