This calculator provides the calculation of energy discharged by a battery. Calculation Example: The energy discharged by a battery is given by the formula E = V * I * t,
Discharging your battery at a higher rate will increase the temperature in battery cells which as result will cause power losses. e.g, a 100ah lead-acid battery with a C-rating of 0.05C (20 hours) will last about 20-25 minutes instead of 1 hour while running a 50 amp load (remember the 50% DoD limit).
However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery.
Battery Discharge Time Calculator . The battery discharge time calculator helps determine how long a battery will last during operation. The formula is as follows: Discharge time (hours)=Battery Capacity (Ah)÷Load Current (A) Please note that the working temperature and environment can affect the load current and, consequently, the battery

Webb ESE 471 14 Maximum Depth of Discharge For many battery types (e.g. lead acid), lifetime is affected by maximum depth of discharge (DoD) Higher DoD shortens lifespan Tradeoff between lifespan and unutilized capacity Calculated capacity must be adjusted to account for maximum DoD Divide required capacity by maximum DoD 𝐶𝐶𝐷𝐷𝐷𝐷𝐷𝐷=
The faster a battery can discharge, the higher its discharge rate. To calculate a battery's discharge rate, simply divide the battery's capacity (measured in amp-hours) by its discharge time (measured in hours). For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps.
However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery.
For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps. The battery discharge rate is the amount of current that a battery can provide in a given time.
The charging/discharge rate may be specified directly by giving the current - for example, a battery may be charged/discharged at 10 A. However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery.
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).
Example: Suppose you have a battery with a capacity of 50 ampere-hours (Ah), and your load draws a current of 5 amperes (A). Using the Battery Discharge Time Calculator: The calculator will estimate a discharge time of 10 hours.
