Hi people.
Preparing a trip in a country without electricity, I purchased a series
of NB2L (equivalent) batteries for my Canon 350D. As I'll have more
batteries than needed when I return, I would like to recycle them in
electronics circuits of my design. Something is puzzling me with these
batteries though:
a. These Li-Ion batteries have 3 connectors labelled "+", "T" and "-".
b. The voltage (at full charge) between "+" and "-" is about 8 V
c. The voltage between "+" and "T" is about 6 V
d. The voltage between "T" and "-" is 0V !!!!
I would have expected the voltage measured in d. to be about 2V to
respect the laws of physics... Thus my questions are:
1. How can one explain the fact that voltages look inconsistent ?
2. What could the exact usage of all connectors be (especially the "T")
? (Is it a feature of Li-Ion batteries?)
3. Would it be safe to use only the "+" and "-" in electronic circuits
?
4. Where I could get a detailed description of the batteries internals
? (Googling a lot, even for the "offical" Canon NB2L batteries, didn't
help much.)
Thanks for any help.
