All:

I want to use an AC/DC voltage source to replace a device that only takes
4 D-cell batteries. What would the equivalent DC power and current
ratings be for an AC/DC supply?

Thanks in advance!

You'll need a 6 VDC supply, and the current rating cannot be determined
from what you provided. That depends on the device you are running. A
"standard" hobbyist DC power supply should be fine, but verify first.

Errr.. maybe. Standard batteries are 1.5 volts each,
connecting them in series is additive, but there's no guarantee
the device connects them in series. I'll grant that,
if said device has any digital components, 6V is the most
likely design voltage.

A 5VDC supply should work, and they are more commonly available. A
battery-powered device needs to be designed to work with aging
batteries, and common alkaline or carbon-zinc/zinc chloride batteries
drop in voltage quite a bit as they discharge.

I would look for a 5V 1A DC "wall wart".

A 6 volt wall unit from Radio Shack.

For the average radio or cassette player,
I'l look for something with a 500milliamp capacity.

That depends on whether the batteries are in series of
parallel; you cannot determine it with the given
information. No one can.

If the batteries are in series, as in a flashlight of positive to negative,
it would be 4 x 1.5 or 6 volts. The device should have the power rating on
it. Most adapters can handle small devices. There are multi-voltage
adapters available.

I dont think I've ever seen any consumer appliance that runs on 4x D
cells in parallel.

And if it does, he's gonna need a real hefty amperage power supply. My
kid had a toy that ate 4 D batteries before lunch. The voltage
requirement was for 6 volts. A 1 amp transformer didn't have enough
oomph, but a 2 amp one did. About the only thing I can figure out about
batteries (AAA, AA, C, D) is that the bigger they are, the more current
they can supply, given that they are all about 1.5 volt nominal.

1.5, 3.0, or 6.0 volts, nominal, depending on how the batteries are aligned
with each other.

Take the device to your supplier (Radio Shack?) and trust the male behind
the counter to deduce what you need.

Oddly enough, I own a flash light that takes 8 D batteries. Parallel sets of
four.

Different types of batteries can supply different amperage.

High: Alkaline, Nicad, Nickel metal hydride.

Medium: zinc chloride.

Low: Carbon managanese dioxide.

Have one in easy reach: It's a flashlight. Have
another in the garage. Have an r/c car that uses that
config. Lots of them around.

Odd. I've never seen a 4D flash light with the batteries in parallel. Just
the one I got years ago which has 8 D cells. But, with two sets of four, it
take the same PR-12 bulb that my other 4D light takes.

I have to really question that. It would mean that your flashlights
and R/C car run on 1-1/2 volts. Not very likely.
