Hello, I don't know how many times a day I can recharge. Because:
1. The current battery is a lithium battery, so the lithium ions have been activated. Usually you just need to charge it fully. Don't charge it for too long. it will take two hours. It is ready to be removed.
2. Under normal circumstances, the computer can be charged when used at 20% capacity. When charging, you should try to charge it fully at the same time, because the battery has a lifespan. Reducing the number of charging times will extend the lifespan.
3. Discharge the battery once a month. You can turn off the battery and then recharge it.
How many times can a lithium battery be discharged and charged?
The battery is almost empty, it's time to recharge it! In your case, the protection circuit cuts off the power when the battery voltage is lower than3.67V to ensure it will not be over discharged. You leave it for a while, allowing the chemical reactions in the battery to overtake the discharge, so the voltage increases and the protection circuit turns back on, so there is voltage again.
The lifespan of a lithium battery is 500 charge cycles. For example: a lithium battery only uses half its charge the first day, then fully recharges. If it's still the same the next day, that is, charge it after half use and charge it twice in total. This can only be counted as one charge cycle.
The battery capacity will be reduced a little. However, this power reduction is very small. If the battery is of good quality, it can still retain 80% of its original capacity after several cycles. Many lithium battery products can still be used normally after two or three years.
But then again, products ultimately have a lifespan and lithium batteries also need to be replaced. The so-called 500 times means that the manufacturer has achieved approximately 625 recharges at a constant depth of discharge (80%), reaching 500 charge cycles.
Another calculation will make things clearer: 625×80%=500 (ignoring factors such as lithium battery capacity reduction). In practice, due to various life influences, including the depth of discharge during charging is not constant, so "500 charging cycles" can only be considered for reference.
For mobile phones and other small electronic devices, you should immediately unplug the power cord (including the USB interface for charging function) after charging and continue to connect it, whether it is a laptop or a cell phone. be careful not toCompletely drain the battery. Also make sure to let the battery drain (automatic shutdown). If you go out, you can fully recharge the battery, but charge your devices at any time if conditions permit.

Precautions for correct charging of lithium batteries: < p>1. Avoid charging at too high temperatures
If the lithium battery is used in an environment above the specified operating temperature, i.e. above 35°C, the power of the battery battery will continue to decrease, that is, battery power will not last as long as usual. Also charge the device if you are at these temperatures.
Damage to the batteryThe damage will be greater. Even storing batteries in a hot environment will inevitably result in damage corresponding to the qbattery quality. Therefore, trying to maintain a proper operating temperature is a good way to extend the life of lithium batteries.
2. Avoid charging at too low temperatures
If you use lithium batteries in low temperature environments, i.e. below 4°C, you will also find that the battery life Battery life is reduced. . Some mobile phones The original lithium battery cannot be charged even in a low temperature environment. But don't worry too much, this is just a temporary situation, different from using in high temperature environments. Once the temperature rises and the battery molecules are heated, the battery immediately returns to its previous capacity.
3. Use often
Life is in movement. If you want to maximize the performance of a battery lithium-ion, you need to use it frequently to keep the lithium battery's electrons in a fluid state. If you do not use lithium batteries frequently, remember to cycle the lithium battery every month and perform power calibration, that is, deep discharge and a deep load.
