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 most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery. The unit of Ah is commonly used when working with battery systems as the battery voltage will vary throughout the charging or discharging cycle.
The energy stored in a battery, called the battery capacity, is measured in either watt-hours (Wh), kilowatt-hours (kWh), or ampere-hours (Ahr). The most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery.
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.
Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.

Battery life can be extended by storing the batteries at a low temperature, as in a refrigerator or freezer, which slows the side reactions. Such storage can extend the life of alkaline batteries by about 5%; rechargeable batteries can hold their charge much longer, depending upon type. [69]
You likely need 5 batteries to achieve the correct operating voltage. Furthermore, if you want to take better care of your batteries, you can consider adding another set of 5 batteries in parallel to reduce the current load on each individual cell. Having a second set of batteries in parallel will reduce the discharge rate to ~1.2 C, generating ...
• Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity. Along with the maximum continuous power of the motor, this defines
The ampere-hour (Ah), which measures how much electric current a battery can produce for an hour, is the common unit of capacity. We determine the size of electrical charges by dividing the electrical current by the passing of time. The milliampere-hour (mAh), where 1 Ah = 1000 mAh, is a more useful measurement that is occasionally used ...
It is reasonable, though, to consider the maximum current a battery can safely deliver. That value will depend on all kinds of things, including the chemistry of the battery, but the maximum discharge rate is almost always tied to the capacity. That means that given a particular technology, a battery with double the capacity can deliver double ...
$begingroup$ In theory you can calculate the short-circuit current of a battery. It is just Voc / Rs where Voc is open circuit voltage and Rs is the effective series resistance of the cell. The short circuit current will not be useful for your purposes right now, though.

Battery life (or lifetime) has two meanings for rechargeable batteries but only one for non-chargeables. It can be used to describe the length of time a device can run on a fully charged battery—this is also unambiguously termed "endurance". For a rechargeable battery it may also be used for the number of charge/discharge cycles possible before the cells fail to operate satisfactorily…
