Customer ServiceIt is important to note that battery capacity is not the same as the power output of a battery. The power output of a battery is the rate at which it can deliver energy, whereas the capacity of a battery refers to the total amount of energy that it can store. Calculating Battery Capacity. If you want to know the capacity of a battery, you can calculate it using a simple
Customer ServiceThe battery shelf life is the time a battery can be stored inactive before its capacity falls to 80%. The reduction in capacity with time is caused by the depletion of the active materials by undesired reactions within the cell. Batteries can also be subjected to premature death by: Over-charging; Over-discharging; Short circuiting

Customer ServiceThis free online battery energy and run time calculator calculates the theoretical capacity, charge, stored energy and runtime of a single battery or several batteries connected in series or parallel. The current drawn from the battery is calculated using the formula;
Customer ServiceFormula: charge time = battery capacity ÷ charge current. Accuracy: Lowest. Complexity: Lowest. The easiest but least accurate way to estimate charge time is to divide battery capacity by charge current. Most often, your battery''s capacity will be given in amp hours (Ah), and your charger''s charge current will be given in amps (A).

Customer ServiceEnter the charging current in the desired unit (A or mA). If the battery is not fully discharged, enter the current state of charge (SoC) as a percentage. The calculator will instantly display the estimated charging time in hours and minutes. The calculator uses the following formulas to calculate the charging time:
The time required to charge a battery pack based on its capacity (Wh, kWh, Ah, or mAh) and the charging current (A or mA). Charging Current The current supplied by the charger to charge the battery pack. Current State of Charge (SoC) The current charge level of the battery pack as a percentage.
To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
If the capacity is given in amp-hours and current in amps, time will be in hours (charging or discharging). For example, 100 Ah battery delivering 1A, would last 100 hours. Or if delivering 100A, it would last 1 hour. In other words, you can have "any time" as long as when you multiply it by the current, you get 100 (the battery capacity).
The energy in Joules (in watt seconds), is calculated using the following formula; The charge in the battery is calculated using the formula; Where; Qbatt is the charge in the battery in Coulombs (C), Cbatt is the rated Ah of the battery. The total terminal battery bank voltage is calculated using the formula;
To calculate charging time using Formula 2, first you must pick a charge efficiency value for your battery. Lead acid batteries typically have energy efficiencies of around 80-85%. You're charging your battery at 0.1C rate, which isn't that fast, so you assume the efficiency will be around 85%.
