can I use D cell to replace AAA battery?

Question

About primary battery,
AAA cell has a voltage at 1.5V
and D cell also has the same voltage at 1.5V

Can I use D cell to replace AAA cell?

Regardless of their sizes, what is the difference between AAA and D cells?
Any damage by D cell on AAA device?

Thanks

Answer 1

Under most conditions you can use a D cell without any problems.

The exception is that a real cheap device might depend on the higher internal resistance of the AAA cell to limit current. For example, I have a LED flashlight with 9 white leds that uses 3 AAA batteries and no current limiting resistor. If I were to substitute 3 D cells, the leds would probably burn out.

Answer 2

A D battery is the same voltage as an AAA battery so there is no problem in replacing the AAA with the D, other than making it fit. The D battery will have much more capacity and last much longer than the AAA battery, but this is probably why you want to do it.

Answer 3

The difference between the two besides the size, is the life of the battery. Inside of the battery are electrolyte plates wrapped around each other. the more plates, the longer it takest all the electrons to move from one pole to the other.

this measurement is referred to a maH or milli-amp Hours. It depends on the manufacturer on what the actual value is, but a typical D cell will last signifigantly longer than a typical AAA cell battery.

if your building a device, there should not be a problem if the specifications rely on the voltage being 1.5 Vdc.

Answer 4

I am an electrician, too.

Robert's answer is pretty darn good. I'm not sure his "plates" description is quite as accurate, but the overall answer is correct. I don't know why anyone would give it a "thumbs down". I gave it a "thumbs up".

Answer 5

volts amps and resistance all are connected if their all 1.5 v maybe the amps are higher or the resistance or ohms are are lower make scenes? no? well sorry hahah
