I didn't know you could do that

Hi,

I'm sure that you'all like me, have several handphones/videocams n
batteries which u do not use anymore. How can I adapt the batteries
to other uses such as to power other appliances like portable radios
etc How do I find out what the voltage is n which of the (output)
points do I tap ?? e.g. my cellphone -Motorola "Talkabout" battery
has 4 connection points.

Or do I need to go to another group for these activities ??

Thanks for any leads.

Buy from an electronics store like the Shack a instrument called a VOM
(Voltage Ohm meter). It will allow you to test circuits and measure the
actual voltage of a battery, electronic circuit, or household AC voltage.
The cost is around twenty to fifty dollars. It would tell you the voltage
available at each of the 4 connection points on your Talkabout battery.

(Pun intended?)
You can get a cheap volt meter in a variety of places and I think most
batteries have the voltage on them.
For most things it is a matter of making the batteries match the voltage of
the intended device and finding a way to physically connect them.
Probably more trouble than its worth.

A single battery cell always puts out the same voltage when fully charged.
Lead acid = 1.5, Ni-Cad =1.2 and I'm not sure what Li-On is.

So a six volt Ni-cad will have five separate cells in them and these usually
take the form of five small batteries soldered together and wrapped in
plastic.

About the only exception to only having to match voltage that I am aware of
is in using LEDs as a light source.
Batteries have an internal resistance which can be ignored with most devices
but LEDs have almost no internal resistance in one direction and will draw
as much current as they can. A good battery with low resistance can burn up
a LED in short time. But it will be bright.

Li-ion = 1.2V

best adaptation ive ever done is to use a 3310 battery for my 9210

easiest = 8210 battery in 3310...hehehehehe
