9v Battery

Having had an acoustic guitar that was a real pain to change batterys I found that the Energizer e2 Lithium lasted longer than anything else and the Energizer e2 Titanium was best of the non lithium batterys.

I also found that the Panasonic digital alkalines are almost as good as the e2 Titanuims.

Duracell coppertops were OK but the Panasonic alkalines that the Dollar store has were just as good if not a little better and are much cheaoer.
 
I on the other hand despise Eveready batteries. In too many applications (not just MI) with low draw, they just do not last as long as Duracells. Not at all for me. I won't trust them at all.

As for rechargables, the problem is that (at least older technlology) a fully charged rechargable battery is only charged to about 8.00 VDC. And many audio applications require a minimum of 7.5 VDC, so they drain pretty quickly. We tried rechargables in our wireless mics, and couldn't depend on them for a whole night (three or four sets).

Thanks for the quick response. I know that todays rechargeable batteries can handle modern cameras and electronics. That's why I was wondering, plus I was being waste conscious :)
