But....

I have the original manual for my 45 CL-4, when I got it a number of years ago. In the section regarding “Power Supply” aside from not mentioning Lithium batteries (yes, yes I know, I know, way, way before its time) it does mention the P-50 power pack and the N-22 or N-23 A/C power supply (both of which has been discontinued for a very long, long time).

The newer manual (obtained on-line as a pdf) for the 45 CL-4, “plain unit” (for lack of a better word, i.e. not the Digital or Digital Basic kit), again under the section "Power Supply", you will note it drops the mention of the long discontinued N-22 or N-23, but still mentions the P-50 power pack. Once again it does not mention anything regarding lithium.

My point…. If they edited the manual to include dropping the mention of the A/C power supply, surely they would have included the disclaimer about lithium, if they were so worried about it.

I still think that the circuitry for the newer 45 CL-4 Digital is much different, and more importantly I think when they say not to use lithium, they are referring to some lithium batteries that are indeed of a higher power rating per battery then others (1.75v).

The brand of lithium batteries that I use is rated 1.5v each, same as the alkaline.

Of course this is all a moot point until / if Metz/Bogen ever decides to provide a more concrete and official response, regarding that "capacitor thingie".
