Using a wireless with rechargables !!!

[axe...@ilos.net]

What.....if any....are the disadvantages of using rechargable 9V
batteries in a wireless guitar setup. It would seem to be a big
advantage (price wise) to buy 2 batteries.....and take a charger with
you on the job. Have one battery charging while using the other.
Yet....no one seems to want to do this. Why ???

I asked about recargables in effects not too long ago. It seems the internal
resistance is a lot different.

Also,If you look at the rechargable packages, you'll
see that the "9V" are actually 7.2 volts- that might not be enough juice for
good tone.

Another thing is that they do'nt fade away. They'll do just fine until they
die and it only takes them 3 or 4 seconds to die. This is great for using
with tape machines because you get good tone until the end, but in a wireless
at a gig, if it starts going in the middle of a measure of music, it will be
stone cold dead at the end of that measure. None of this "it sounds funny
-I have to change it at the end of this song", no sirree.

Well, the reason *I* don't is because my transmitter
begins shutting down at 7V. A NiCad battery is only
7.2V at it's best, and that doesn't last too long.
After multiple rechargings a NiCad will begin to lose
its ability to go to a full charge.
9V batteries are built out of 6 cells. A regular
cell (carbon or alkaline) holds a charge of 1.5V; a
NiCad only 1.2V. So, the NiCad batteries they sell
"FOR 9V APPLICATIONS" are only for those applications
that will run off a reduced voltage. My transmitter
is NOT one of those. A NiCad battery will result in
the onset of distortion within an hour or so. Really
nasty distortion, too.

Because the actual voltage capacity of a 9 volt NiCd is 8.4 volts.
That's right on the ragged edge of good operation for most wireless
units. You would tend to have noise/drop-out/range problems.

I use recharageables in my wireless with no problem except the above
mentioned "3 to 4 seconds to die".

As for the voltage, I've had no problems. I use a Samson true diversity
wireless......

I got a rechargable set just for that and it was a waste of $30.! I have an
Audio-Technica unit and use Duracell's exclusively. The rechargable was about
1/8 of an inch bigger and didn't fit into the transmitter. They also don't
charge much above 7.5 volts. Trust me, go buy a brick or two at the local
wholesale club. Once you've got a few shows on them, and/or they read 7 volts
or below, give them to the kids for toys or whatever. 7 volts might run a
Power Ranger or a smoke detector, but doesn't cut it for a wireless. Hope this
helps.

I use rechargeables in my Nady Wireless One with no problems. except the
"immediate death" syndrome.....
