The gel cell should certainly provide enough current. Your radio will not burn
up, it will draw the amount of current that it needs, regardless of how much the
gel cell is capable of providing.

Thanks everyone ! But about the current, how much current is a gel cell
going to provide ? My concern was burnin gup the radio because the battery
would produce too much current. That was why I mentioned the mathematical
handicap LOL. I was thinking I would have to reduce the current with a
resistor or something, and had no idea how I would calculate the value of
the resistor. Thanks very much S.
P.S. the "V" is "V for Victory". I couldn't figure out how to make a CW
version that I could insert in a signature.

Hey V...go down to Battery World or something close, perhaps a local auto
parts store...and buy yourself a 14Ahr sealed lead acid battery (gel cell)
and a charger for it.

I run most of my stuff off this type of battery.

No hydrogen build up either.

Hi.
As a ham radio man, I am hoping you can help me out. I have a DX394
receiver
and usually use ac to power it. I can run from a car battery, with the
adaptor. It requires 12 volts at 500 Ma. What I am wondering is if I can
build an emergency power supply so I can listen using batteries when the
trees take out the power lines s.

What I thought I could do is get a 9v lantern battery and add two 1.5
volt
D
Cells . I am not mathematically inclined in the least. If I connect the
positive of the lantern and the negative of the lantern to the
corresponding
terminals of the two D Cells, and connect all that to the adaptor plug
for
the back of the receiver, will it supply sufficient current to run
properly
or not ? I could probably get an actual car battery, but would rather
not
have that in the apartment.
