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 total resistance includes the internal resistance of the battery as well as the external resistance. As resistance is inversely proportional to the current for a constant voltage, for maximum current the resistance needs to be minimum. Here, we need to find the maximum current I m a x provided by the battery.
The minimum value from the above equation will be obtained when the squared term will be equal to zero. Hence, when the external resistance will be equal to the internal resistance of the battery, the total resistance will be minimum and the current will be maximum.
So, yes. Batteries have a max current drain (given by design and physical/chemical limitations) and yes the storage rating (being Ah, Wh or Joules) changes depending on battery design and load applied, and yes Wh is a better way to compare batteries because it takes voltage in account.
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 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.
