Battery Charging Time Calculation

A few days ago, the wireless mouse ran out of power, so I went to get a new battery and suddenly found that the home's No. 5 battery was all used up. I thought I had to buy it again, And suddenly remembered that there was a rechargeable battery at home, as a result, find out the gpchao charger that has not been used for a long time ...... You have not guessed it wrong. You have not used it for a long time. You cannot remember the charging time. The instruction manual has been thrown away for a long time. No matter how much it is, it is directed first. You can just pull it out tomorrow morning. You can use this notebook first.

This morning, I found that a group of batteries of the charger had been flushed, and the other group was not good. I felt very surprised, So I google it. It was discovered that the battery had been active for more than 20 years and there was no idea that there was a dedicated computing method for the battery charging time !!! In retrospect, it was quite good to learn physical and electrical science.

However, I believe there will be more people who do not know the charging formula before, just like me. I would like to share with you that this is very practical:

Charging time = battery capacity/charger electric traffic * 1.1

The following explains

Battery capacity:

It is the XXXX mAh or ma indicated on the battery. For example, if my gpsuperba battery is 1800mA, the new battery method is a little different: standard charging for 14-16 hours * 80mA, fast charging for 4-6 hours * 200mA, in fact, you will know about 1200mA.

Charger electric traffic:

This parameter is used on the charger. For example, gpchao is written as follows: 130mA (V. 5), 70mA (V. 7), 17mA (9 V ), this 130, 70, and 17 is the so-called electric traffic. Just select the corresponding battery value. 9 V refers to the kind of battery with the same positive and negative poles, generally, many toys are used.

1.1:

This is to consider the loss of battery charging, So multiply by a charge loss coefficient.

So I figured out that the charging time of my gpsuperba battery (No. 5) was 1800/130*1.1 = 15.2, so the battery was full after 15 hours. Have you learned it, tell more people you don't know.
