According to one The maximum continuous discharge is 2.2 A (2200 mA) not 20A. In that case, drawing 20A for more than a few seconds will overheat the cell. The cell has overcurrent detection at 4 - 7 A. 18650 and 26650 cells vary quite a bit in their maximum continuous discharge current.
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.
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.
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.
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.
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.
Formula: Battery charge and discharge rate in amps = Battery capacity (Ah) × C-rate let's say you have a 100ah lead-acid battery. 100Ah lead-acid battery has a recommended charge and discharge rate of 5 amps let's say you have a 100ah lithium battery. 100Ah lithium-ion battery has a recommended charge and discharge rate of 50 amps

C-rate is used to scale the charge and discharge current of a battery. For a given capacity, C-rate is a measure that indicate at what current a battery is charged and discharged to reach its defined capacity. A 1C (or C/1) charge loads a battery that is rated at, say, 1000 Ah at 1000 A during one hour, so at the end of the hour the battery reach a capacity of 1000 Ah; a 1C (or C/1) discharge ...
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.
It helps in determining how fast a battery can be safely charged or discharged, affecting overall efficiency and longevity. Common FAQs. What does a 1C rate mean? A 1C rate means that the charge or discharge current is equal to the battery''s capacity. For example, a 1C rate for a 20Ah battery would be 20A. How does the C rate affect battery life?
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
Voltage (V) – Power. Voltage is the measure of electrical potential in a battery. It determines the power output of your cordless tool.

It depends (all other things equal) on the current draw. A 4A-hr battery, in theory will last for 1 hour at 4A current draw. For many tools, maximum draw will likely be a lot more than 4A... especially under heavy loads. It really depends on how you run the tool.
During a battery discharge test (lead acid 12v 190amp) 1 battery in a string of 40 has deteriorated so much that it is hating up a lot quicker than other battery''s in the string, for example the rest of the battery''s will be around 11,5v and this particular battery will be at 7 volts, the temperature rises to around 35degres C. (15 more than the rest. So my question is, how w …
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.
