Battery calculator
Welcome to the Swaytronic - Accumulator Calculator our new tool to answer / calculate almost all your questions about charging time, energy density, operating time, power density and energy content of an accumulator.
We have tried to provide you with a tool with which you can calculate and thus select the suitable accumulator. Or, if already available, you can check here whether the battery is suitable for the planned use. Please note that the calculated values based on your input are of a theoretical nature and may not be transferred 1:1 to practice, as there are various influencing factors, some of which cannot be predicted.
(Example: 95% efficiency with 1A charging current, 950mAh or 0.95A arrive at the battery or are available for charging).
Other factors that influence the charging time are ambient temperature, battery temperature and the condition and age (year / number of cycles) of the battery.
Calculating the charging time of an accumulator:
The charging time of an accumulator depends on various influencing factors such as technology, charger and charging software or their settings and power values as well as the power consumption or charging rate of the accumulator. With our battery calculator tool you have the possibility to calculate the charging time of your battery - based on the values that the battery allows or consumes. The actual charging time depends on various factors, including the efficiency of the charger, which determines how much charging power actually reaches the battery.

With our tool, all technologies / types of cells and accumulators can be calculated. The specific values or nominal voltages of the different chemical cell technologies are decisive for the calculation. (Example 3.7V=LiPo ; 3.2V=LiFePO4 etc.)
Calculating the energy content (energy density) of an accumulator
The energy density (gravimetric watt-hour per KG) indicates the amount of energy that can be stored on a specific weight. The amount of energy, watt-hour, is calculated from the capacity in Ah (ampere hours) x the voltage V (volts)=XY watt-hours. The number or amount of watt-hours is then put in relation to the weight of the battery. (Wh/KG)=Specific energy density.
With our tool for calculating the operating time, we offer you the possibility to determine how long your accumulator will work under the defined power values with the power value watt or ampere.
You can carry out the calculation with the nominal values of amperes or watts.
Calculation of the battery life, also called operating time:
The operating time of an accumulator is simply expressed as the capacity (Ah) / measured current consumption. This tells you how long you can operate your consumer.
Caution: The C-rate is always a theoretical discharge value that can be achieved under optimal conditions (state of charge, age, operating and ambient temperature, etc.). For applications without an active or passive cooling system, we recommend planning a power reserve of 15-20%.
The power density, also called C-rate:
The power density (watt or ampere), i.e. the possible current output of the accumulator, is nominally indicated with a C-value. The C-rate refers to the nominal capacity of the accumulator and serves as a factor for calculating the possible current output. For an accumulator with 100mAh capacity and a continuous discharge rate of 35C, the possible discharge current is 35A.
With our tool, all technologies / types of cells and accumulators can be calculated. The specific values or nominal voltages of the different chemical cell technologies are decisive for the calculation. (Example 3.7V=LiPo ; 3.2V=LiFePO4 etc.)
Calculation of the energy content of an accumulator:
The energy content (watt hours) indicates the amount of energy available per hour. The amount of energy, watt-hour, is calculated from the capacity in Ah (ampere hours) x the voltage V (volts)=XY watt-hours.
