What happens if you put 2 9v batteries together?
Originally Answered: What would happen if I stick two 9-volt batteries together.
The two batteries would rapidly discharge each other and heat up to the point where they would burn you if you held them.
They might get hot enough to explode..
How much voltage does 4 AA batteries have?
Most AAA, AA, C and D batteries are around 1.5 volts. Imagine the batteries shown in the diagram are rated at 1.5 volts and 500 milliamp-hours. The four batteries in parallel arrangement will produce 1.5 volts at 2,000 milliamp-hours. The four batteries arranged in a series will produce 6 volts at 500 milliamp-hours.
