Lithium battery charge time and discharge time calculation

Generally, the battery capacity is indicated on the battery, in milliamperes, the larger the value, the greater the capacity. For example: 1200mAh means that the capacity of the battery is 1200 mA. At the same time, the charger is generally also marked with the charging current, also in milliamperes. In this way, the length of the battery charging time can be simply calculated as follows: the battery capacity is divided by the charging current, and then multiplied by a factor of 1.2 (or 1.1), and the unit of time is hours. For example: the battery capacity is 1200 mA, the charging current of the charger is 600 mA, the charging time is (1200 mA/600 mA) u0026 TImes; 1.2u003d2.4 hours, then the charging time for this battery using this charger is Is 2.4 hours. The above calculation method does not apply to new batteries. Generally speaking, when a new battery is charged for the first three times, especially nickel-cadmium batteries and nickel-hydrogen batteries, the standard charge is about 15 hours (0.1C), so that the battery life can reach the maximum value. In the future, you can refer to the above method to calculate the battery charging time. I can give you a simple formula: charge and discharge time (minutes) u003d capacity * 1.1 / current (mA) * 60 The relationship between battery charging time and charging current is the battery capacity divided by the charging current to get the charging time, considering the loss in the charging process , So multiply the calculated charging time by the constant of 1.1 or 1.2. Based on the logo, you can calculate an approximate time. If it is a normal charger, and the current is very small, the charging time must be very long.
