Product Description
General battery capacity is indicated on the battery, in milliamperes, the larger the value of the larger the capacity.
Calculation of 18650 cylindrical battery charging time and discharging time:
For example, 1200mAh means a battery capacity of 1200 mah. Chargers are also marked with charging current, again in milliamperes.
Thus, the battery charge time can be calculated simply by dividing the battery capacity by the charging current and multiplying by the factor 1.2 (or 1.1) in hours. For example, the 18650 High security lithium ion battery capacity is 1200 ma, the charger charging current is 600 ma, the charging time is (1200 ma /600 ma) &TImes; 1.2=2.4 hours, then the charging time of this battery using this charger will be 2.4 hours.
These calculations do not apply to new batteries. Generally speaking, when new batteries are charged for the first three times, especially nickel-cadmium batteries and nickel-hydrogen batteries, the standard charge is about 15 hours (0.1c), which can make the battery use time reach the maximum. Later, the battery charging time can be calculated by referring to the above method.
What is the charging current on the charger?
Here's a simple formula: charge/discharge time (min) = capacity *1.1/ current (mA) *60
The relationship between the battery charging time and the charging current is that the battery capacity is divided by the charging current to get the charging time. Considering the loss in the charging process, the calculated charging time is multiplied by the constant of 1.1 or 1.2.
According to the sign, you can calculate the approximate time. If it is an ordinary charger, and the current is very small, the charge time must be very long.
