how to use this calculator? 1 - Enter the battery capacity and select the unit type. For example, If you have a 50 amp hour battery, enter 50 and select Ah. 2 - Enter the battery c-rating number (mentioned by the manufacturer on the specs sheet of your battery). Enter "Calculate" button to find out the results.
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.
The battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery can provide. To calculate the battery discharge rate, you need to know the capacity of the battery and the voltage.
Energy is calculated by multiplying the discharge power (in Watts) by the discharge time (in hours). Like capacity, energy decreases with increasing C-rate. Cycle Life (number for a specific DOD) – The number of discharge-charge cycles the battery can experience before it fails to meet specific performance criteria.
As the discharge rate ( Load) increases the battery capacity decereases. This is to say if you dischage in low current the battery will give you more capacity or longer discharge . For charging calculate the Ah discharged plus 20% of the Ah discharged if its a gel battery. The result is the total Ah you will feed in to fully recharge.
Formula: C-rate in time (minutes) = (1 ÷ C-rate) × 60 The chemistry of battery will determine the battery charge and discharge rate. For example, normally lead-acid batteries are designed to be charged and discharged in 20 hours. On the other hand, lithium-ion batteries can be charged or discharged in 2 hours.
Capacity is calculated by multiplying the discharge current (in Amps) by the discharge time (in hours) and decreases with increasing C-rate.

This article contains online calculators that can work out the discharge times for a specified discharge current using battery capacity, the capacity rating (i.e. 20-hour rating, 100-hour rating etc) and Peukert''s exponent.
Using a battery discharge calculator can give you a deeper understanding of how different battery materials affect discharge rate. Carbon-zinc, alkaline and lead acid batteries generally decrease in efficiency when they discharge too quickly. Calculating discharge rate lets you quantify this.
As you might remember from our article on Ohm''s law, the power P of an electrical device is equal to voltage V multiplied by current I:. P = V × I. As energy E is power P multiplied by time T, all we have to do to find the energy stored in a battery is to multiply both sides of the equation by time:. E = V × I × T. Hopefully, you remember that amp hours are a …
Estimating Maximum Current – using the graph and calculation as shown above you can use the measured OCV and DCIR to estimate the discharge current at the minimum cell voltage.
Battery capacity refers to the amount of energy a battery can store. It is a critical metric, influencing the overall performance and lifespan of the battery. The higher the capacity, the longer a battery can provide power. Factors Influencing Capacity. Several factors influence battery capacity, including voltage, current, and efficiency. The ...

Constant current discharge time t=battery power c/charging current i. Assuming that the battery capacity is 2000MAH, set the charging current to 400MA, and the theoretical discharging time is 2000/1000=5 hours. 0.5C calculation formula is as follows: charging time t=battery power c/charging current i
Depth of Discharge (DoD) refers to the percentage of a battery''s capacity that has been discharged relative to its maximum capacity. It is a critical parameter in rechargeable batteries, particularly in applications like electric …
Primary batteries can only be used once and must be disposed of or recycled. Secondary batteries can be reused after they are recharged. Lithium-ion batteries are the most popular type of secondary battery due to their high discharge rates and long life spans.
I found two ways to calculate the power. The first one was simply using the voltage curve as a function of state of charge for different C- Rates. Then multiplying the Current with the voltage and getting my power. P (SOC) = U (SOC) * C-Rate.
For example, if you have a lithium battery with 100 Ah of usable capacity and you use 40 Ah then you would say that the battery has a depth of discharge of 40 / 100 = 40%. The corollary to battery depth of discharge is the battery state of charge (SOC). In the above example, if the depth of discharge is 40%, then the state of charge is 100% ...
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.

Battery discharge time can be calculated using the formula: Discharge Time = Battery Capacity (in amp-hours) / Load Current (in amps). How long will a 155Wh battery last? To determine the time, you need to know the load current. If the load uses 100W (155Wh), and assuming 12V, the discharge time would be around 155Wh / 100W = 1.55 hours. How long …
