Hi All
  I have descovered that the enegizer Lithium crv310 output is 3
volts. I disassembled it to find that it contained two 3 volt batteries
in parallel. Each battery is the same size as a AA cell. My question is

I made a easy way to obtain Phenole :
you need -- NH4HCO3 or NaHCO3
        -- Salicilic acid HO-C6H4-COOH
1st step

Is there someway of converting moles into conductivity and vice-versa?
For example I have a Salt solution that measure 80uS, from this can I find
out what the molar concentration is?
Cheers

what is the 9 volt battery that have the best Ampere/hour?
Thanks

Does anyone know of a vendor that makes thin-film batteries? I need
100 volts in the pA to nA range and they need to be compact and
rechargeable. Cells that are series connected should do the job.
Several web sites claim to have the technology, but none of them have

I recently bought a cordless phone, which came with a NiCd battery.  In the
manual it says:
"To reduce the risk of fire, use only 3.6V 850mAh Nickel
Cadmium (Ni-Cad) cordless telephone replacement

Ok so I have a wireless device the plugs into the wall with no option to
make it completely wireless (darn..guess I have to do it).
What I know is that the power supply outputs is DC 5V/2.5A, switching
type.  Also the tech specs say "Power Communication 4.5W (900mA x 5v)"

guys,
I am playing with the idea of having a battery backup for my boats VHF
radio in case the main battery or electrics fail.
With the long storage life of those batteries I could keep them for a
