A battery can supply a current as high as its capacity rating. For example, a 1,000 mAh (1 Ah) battery can theoretically supply 1 A for one hour or 2 A for half an hour. The amount of current that a battery actually supplies depends on how quickly the device uses up the charge. What Factors Affect How Much Current a Battery Can Supply?
The higher the internal resistance, the lower the maximum current that can be supplied. For example, a lead acid battery has an internal resistance of about 0.01 ohms and can supply a maximum current of 1000 amps. A Lithium-ion battery has an internal resistance of about 0.001 ohms and can supply a maximum current of 10,000 amps.
The amount of current a battery can supply is determined by several factors. The first factor is the battery’s voltage. This is the potential difference between the positive and negative terminals of the battery, and it determines how much power the battery can supply. The higher the voltage, the more current the battery can supply.
Assuming you have a 12V battery that is in good condition, it can supply up to 30 amps of current. The amount of current that a battery can provide depends on its size and capacity. A larger battery will be able to provide more current than a smaller one. How Batteries are Rated?
Batteries are devices that store energy and release it in an electrical current. The initial current is the amount of current flowing from the battery when it’s first connected to a load. It’s important to know what the initial current is because it can help you determine how long the battery will last and how much power it can provide.
Max discharge current for lipo's depend on the application. For example, quadcopter lipo's generally tend to have very high discharge currents (like 20-25C) How can i calculate the maximum current a battery can provide if the only information i have is: 7.2 V / 11.5 Wh / 1600 mAh.
How many amperes can an alkaline AA battery supply?
From the impedance of the battery, you only need Ohm''s law to calculate the peak current and power the battery can supply. I''ll leave the calculations for you and your understanding. Here is a datasheet from Energizer instead which is more useful for your purpose. Inner resistance is listed as 150-300 mohm. Shoutout to @Hearth and @ScottSeidman ...

What is the maximum current which can pass in a Li_ion battery?
As a rule of thumb small li-ion or li-poly batteries can be charged and discharged at around 1C. "C" is a unit of measure for current equal to the cell capacity divided by one hour; so for a 200mAh battery, 1C is 200mA. Example: common 402025 150mAh battery from Adafruit: quick charge 1C, maximum continuous discharge 1C.

What are the tolerances for the maximum current a battery can supply?
If a battery is specified to deliver 9 amps, and you limit current to nine amps, the battery will likely achieve lifetime performance reasonably similar to what is specified in the datahseet. Going beyond the rated current may not cause immediate failure, but is likely to adversely affect device lifetime. Trying to draw e.g. 10 amps from a 9 ...
