You can hook up an infinitive number of 12 volt batteries in a parallel circuit and still have 12 volts.
The small batteries (dry cells) used for many electronic devices usually have approximately 1.5 volts. Car batteries (which have several cells working in series) usually have around 12 volts. Other batteries may have other voltages.
22 (1.5 volts each) AA batteries
All regular automobile batteries are 12 volts.
Batteries come with different voltages.
24 Volts.
Yes they can just look at how many volts the battery is that came with the gun if you get to many volts it will destroy the gun.
A "C" battery has a 1.5 Volts same with AAA, AA, and D batteries.
Fully charged battery should have 12.6 volts. 75% charged 12.4 volts, 50% charged 12.2 volts, & 25% charged 12.0 volts.
You need to divide the 48 volts by the voltage produced by a single battery.
Depends on the cell chemistry, which determines the cell voltage. And the degree of charging. Can be anything from 3x1.2 to 3x3.6.
Most calculators use 1.5 volts from small button-cell batteries, such as LR44 or CR2032.
I believe that AA batteries are rated at 1.5 volts each, so if you were to take 6 of them and wire them together in series that would produce a circuit that's pushing 9 volts. But recharge AA batteries are only 1.2 volts per unit so a little lower voltage will be the result. I think most devices will still work on the lower voltage. Also these batteries will never last as long as the regular dry cell.
