Fully charged battery should have 12.6 volts. 75% charged 12.4 volts, 50% charged 12.2 volts, & 25% charged 12.0 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.
All AA batteries are 1.5v "though it should say so on the label"
Batteries come with different voltages.
24 Volts.
You can hook up an infinitive number of 12 volt batteries in a parallel circuit and still have 12 volts.
If two 12-volt batteries are hooked up in series, they should measure about 24 volts. However, if they are hooked up in parallel, the voltage should be about 12 volts (while current increases). The voltage on the batteries is an estimate from the point of being fully charged...same as with dry-cell batteries.
A "C" battery has a 1.5 Volts same with AAA, AA, and D batteries.
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.
You need to divide the 48 volts by the voltage produced by a single battery.
12 volt batteries if fully charged should show 14.2 volts
