How to size your storage battery pack : calculation of Capacity, C-rating (or C-rate), ampere, and runtime for battery bank or storage system (lithium, Alkaline, LiPo, Li-ION, Nimh or Lead batteries
To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
Remember a battery is a chemical device, and it is the chemical reaction within the battery that is important to know about regarding whatever circuit the battery is going to power. YES a battery could determine the amount of current flowing in the circuit.
Two batteries connected in series feed a 0.16 Ohm resistor with 80 Watts of power at 3.85 Volts. Each 4 Volts battery is capable of supplying up to 20 Amps of continuous current. Ohm's Law calculation gives 22.36 Amps of current draw for the entire circuit but ... Question 1: How much current is drawn from each battery ?
3 AA's is 4.5V that will dip down to like 3V at end of life. 5V from a USB battery is likely 5V (it can be as low as 4.5V from a computer, especially when under load on a small gauge cable). And it'll be 5V until the battery is depleted. I wouldn't think 0.5V would matter to the LED widget. I'm going to guess either infant mortality or poor design.
The four batteries in parallel will together produce the voltage of one cell, but the current they supply will be four times that of a single cell. Current is the rate at which electric charge passes through a circuit, and is measured in amperes. Batteries are rated in amp-hours, or, in the case of smaller household batteries, milliamp-hours (mAH).
ANY battery does not just throw amperage or current; it will first discharge as much current as physically possible based on its chemistry and chemical reaction, and then what limits this discharged current is the resistance of the circuit it is connected to.

*edit You could probably use another multimeter to measure the current draw by connecting it in series with the element you are measuring. Share. Cite.

The maximum current depends very much on the chemistry of the battery. The capacity of the three main (no Lithium) batteries is approximately: Zinc-Carbon: 540mAh; Alkaline: ~1000mAh; NiMH: ~900mAh; The current limit and capacity of any specific battery can be found in its datasheet. For instance, the Duracell MN2400 has the following nice graph:
The important thing to realize here is that the capacity of the battery does not affect the amount of current drawn. Your Mega will draw the same whether it is connected to a 1000 mAh battery or a 5000 mAh battery. The larger battery will just last longer. Tests on my Mega2560 Arduino show that (with no peripherals connected) it draws about 70 mA from a 7V supply, and slightly more …
You can then calculate out what the average current is if the device seems to run in about the same power mode the whole time, to get an average current, but for devices with …

Even at 8A, the battery will be flat after half an hour. And be aware that lead-acid batteries don''t like being left flat. Once run down, they should be recharged as soon as possible, or they may be permanently damaged. *1C is a current numerically equal to the amp-hour rating of a battery. So for an 8Ah battery, 1C is 8A.
But how much current can you safely draw from a AAA battery. I am currently powering my project from a worktop power supply and it draws at 5V 0.45A during normal operations and peaks to 0.7A. Now I need to make it portable and looking for the right battery.

Battery power can also be utilized, with various types available, such as 9V batteries, AA or AAA battery packs, or even lithium polymer batteries. Users can hook up a battery to the Arduino Uno board using the GND and Vin pin headers of the POWER connector. Like with the adapter, the voltage supplied should be within the 6 to 20 V range to maintain …
Short answer: The current drawn from each battery will still be equal to the current in the load resistor because the batteries are still in series. Longer answer: The load resistor in your OP has quite a small value.
You can then calculate out what the average current is if the device seems to run in about the same power mode the whole time, to get an average current, but for devices with higher on-load current, you would need to use an ammeter to measure that peak current.
