When batteries come in different volts what does it mean?

How many volts in three AAA batteries?

Depends on the cell chemistry, which determines the cell voltage. And the degree of charging. Can be anything from 3x1.2 to 3x3.6.

Who makes roadrunner auto batteries?

If you mean who makes OEM batteries for Plymouth Roadrunner they are all labeled Mopar but are manufactured by several different companies

How do you wire 2 batteries together to make 24 volts?

Do you mean 2 x 12 volt batteries? If so:Wire 1st battery's + to load, wire it's - to the + of the 2nd battery.Wire 2nd battery's - to the other side of the load.**********************************************There are two basic ways to wire multiple batteries together, in "Parallel" or in "Series".PARALLELWiring two batteries which have the same output voltage in "Parallel", the output voltage of the combination stays the same but the amp/hour capacity of the combination is equal to the sum of their individual amp/hour capacities.Wiring: Battery 1 Positive to Battery 2 Positive and Battery 1 Negative to Battery 2 Negative is Parallel wiring, retaining the voltage rating of either one of the batteries.WARNINGIt is not a good idea to wire two batteries which have different voltage ratings in parallel because the one with the higher voltage will immediately send current to the other one with the lower voltage to try to make their voltages both the same. The very high current which will flow between the two batteries is likely to make the batteries get very hot. IF THEY ARE CAR BATTERIES THEY COULD EXPLODE!SERIESWiring two batteries which have the same output voltage in "Series" makes their combined output voltage equal to the sum of their individual voltages but the amp/hour capacity of the combination will be no greater than the amp/hour capacity of the smallest battery of the two.Wiring: Bat 1 Positive to Load, and Bat 1 Negative to Bat 2 Positive, then Bat 2 Negative to the other side of the Load is Series wiring and the total voltage of the combined batteries is the sum of both individual voltage ratings.So, assuming you want to get 24 volts out of two similar batteries, you could wire two 12 volt batteries in series.NEVER OPERATE A 12 VOLT ELECTRICAL SYSTEM as in CARS or most BOATS with 24 VOLTS. YOU WILL BURN UP YOUR COMPONENTS AND SOME WIRING.Common Flashlights are simple examples of series wiring. Flashlight batteries are usually 1.5 volts whether they are AAA, AA, C or D size. So flashlights with with 1 battery are operating at 1.5 volts, 2 batteries are 3 volts, 3 batteries are 4.5 volts, etc.

Why are different batteries used to different devices?

Batteries have different voltages because different devices require different voltages to function. Batteries are manufactured to satsfy different devices' energy needs while minimizing voltage loss.

What does a black cable connecting two 12 volt batteries on negative post mean?

That is how you connect 2 batteries in parallel. Like terminals are connected together. With this arrangement you still just have 12 volts, but the amperage doubles. You should also see the 2 positive terminals connected together. If not, then you may have a combination of parallel and series.

Does anyone make a rechargeable 1.5 V D-cell?

If you really mean 1.5 volts, I don't think they are available. As far as I know all or almost all AAA, AA, C & D rechargeable batteries are 1.2 volts. If 1.2 volts will do there are several companies that make 1.2 volt D cell rechargeable NiMh batteries. However, all or almost all D cells made by major name manufacturers are AA batteries packged in a D shell. If AA energy content is enough for you check the links below. If you want the energy content commensurate with D-Cells make sure the current rating is 10,000 mAh (milliampere hours) or higher.

What does the letters on a fuse mean?

amps and or volts

What does KV mean in electrical language?

Kilo Volts K = 1000 so 5KV = 5000 volts

Are there any rechargeable lithium batteries on the market today?

If you mean for a cell phone, then all the lithium batteries will come with a rechargeable option. This might have certain restrictions for certain cell phones, but the dealer should be able to let you know in advance of purchase.

What does it mean by writing V and W in a bulb?

V on a light bulb means volts. W means watts.

What does gp batteries mean?

Gold Peak

How many volts are used in America?

If you mean the USA, there they use 120 volts / 60 Hz.
