[R-390] OT Battery Leakage

[Bill Guyger via R-390]

Don't know about AA's and the 390A's, but back in the day I took a swing through live show production. We had 5 wireless mics in the show and after a couple of battery failures, the producer went off the deep end and required us to change batteries every show. There were 5 shows a day, and each transmitter was a 50 - 100 mw. analog radio, so how much drain was there really..........

We bought a crate of standard 9V. batteries and did as told. That left us with stacks of barely used batteries which we as bored techies began plugging end to end which is possible due to the male and female terminals. Ever seen a 900 V. battery? :-)

How many AA's does it take to power an R-390?

After A/c conversion.....

I was told they were the same by a Duracell engineer.  She had QC 
reports that showed the same data attributed to both.  I wouldn't put 
too much stock in anybody's anecdodal reports of battery life 
(including mine), since usage is a huge uncontrolled variable -- how 
much were the flashlights used, how much were the multimeters used on 
the ohms ranges, and how much were they left forgotten on the ohms 
ranges for prolonged periods?  Also are you sure you were comparing 
the Procells specifically to the "Duracell Plus" batteries I 
mentioned, or could it possibly have been to one of the many other 
Duracell battery product lines?

Best regards,

Charles
