Discharge rate: The calculation assumes a specific discharge rate for the battery. In reality, the discharge rate can vary depending on the load being powered, the temperature, and the age of the battery. Battery type: The calculation assumes a specific type of battery chemistry, such as lithium-ion or lead-acid.
Use the formula: Discharge Time = Battery Capacity (Ah) / Load Current (A). This method considers the battery's capacity and the device's power use. It tells you how long the battery will last before needing a recharge.
There is no generic answer to this. You read the battery datasheet. Either it will tell you the max discharge current, or it will tell you the capacity at a particular discharge rate, probably in the form C/20 where C means the capacity. You know the current you need : 4.61A.
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.
If you work almost every day, go for 4Ah, 5Ah, or 6Ah. With those batteries, you need to charge less than 2Ah or 3Ah. Lastly, consider the power tool. Some power tools require at least a 4Ah battery. With those power tools, you cannot use 2Ah or 3Ah. Whatever you choose, should satisfy these three factors.
On the other hand, the 3Ah tool battery weighs around 1 pound. 3Ah batteries are almost 20% to 30% heavier. Now comes the power difference between 2Ah and 3Ah. A 2Ah battery will provide 2 amps for an hour or 1 amp for two hours. Nevertheless, a 3Ah will provide 1 amp for 3 hours or 3 amp for 1 hour.

You read the battery datasheet. Either it will tell you the max discharge current, or it will tell you the capacity at a particular discharge rate, probably in the form C/20 where C means the capacity. You know the current you need : 4.61A. If the battery data lists a continuous discharge current of 5A or more, you are good.

A 2C battery would need just half an hour to load 100 Ah, while a 0.5C battery requires two hours. Discharge current. This is the current I used for either charging or discharging your battery. It is linked to the C-rate with the following equation: I = C-rate × Q. Runtime to full capacity. It is simply the time t needed to
Tool Battery Capacity Comparison: 2Ah / 3Ah / 4Ah / 5Ah
A 2Ah battery discharge rate is lower than a 3Ah battery discharge rate. But, it depends on the C rate. For example, a 2Ah battery with a 1C rate will discharge at 2AmpsX1=2A. With the same C rate, a 3Ah battery will discharge at 3AmpsX1=3A.
