Subject: Question about battery types and circuit boards.

Hello all and good day to you.

I have the Star Diamond.  I used some typical fresh alkaline batteries in it and
my Star Diamond ran for (I think it was) about 24 hours before I had to change
the 4 AA batteries.

When the next set runs out, I'm going to put those newer batteries in, those
Duracell Ultra ones.  They claim to last longer, and of course they cost more.
I'm interested in whether these Ultra batteries will last 40+ hours or not.

Anyway, I noticed that Energizer has AA batteries that are Lithium batteries,
made for digital cameras and regular cameras.  These cost a lot, $10 for 4 of
them.  Since they are AA and rated at 1.5V (just like all the other AA
batteries) I thought that it would be interesting to plug these Li batteries
into the Star Diamond.  Maybe it'll run for over 100 hours that way.  However,
one thing holds me back.....

On the package it lists the mAHrs (milli amp hours).  This figure was 2000 or
2250, I don't recall  (but it must be a good battery if it has an Expert or
Master ranking.  Ha ha ha!).  But the other "regular" alkaline batteries (both
the regular and the ultra) had a number which was 250 mAHrs *less* than the
Lithium-type batteries.

So voltage is the same but mAHrs is larger for the Li batteries.

Is it safe to use these Li batteries in the Star Diamond?  Or anything else?
((Besides cameras of course, which it is advertised for)).
