Topic: runtime for 9v lithiums in sonosax?

[dr.ph0b]

anyone ever use 9v lithiums instead of alkalines?  what runtimes did you get?  tia

I just went looking for the current draw of the sax and on the sonosax website it said "12V DC to 24V DC, minimum 30mA, maximum 80mA" .....my guess is that the 9 volt lithum won't work.  The two internal 9 volts must be in series giving you 18volts DC.

If it DOES work.....than that 9 volt lithum would power it for a LONG TIME (50 hours).

I have a beyermv-100.....different beast alltogether (but same box), but in my experience Lithiums last upwards of 7hrs. The majority of the battery goes towards providing phantom power.
Both units use internal 9v's for power....

I once got some bad lithiums from Rat-Shack that only lasted ~3hrs, but that's the exception rather than the rule.

From others experience, 9v NiMH batteries are worthless.

Wow, 7 hours for lithiums is very low.  I used to have a beyer mv100 and would run 9v lithiums in it and got about 25 hours.  I ran regular 9v alkalines in it a couple times and got 6-7 hours.  I seem to recall that the beyer uses slightly more current than the 'sax, so I'd imagine you'd get at least 25 or maybe 30 hours.

Also, I once kept running the beyer on lithiums once the blinking low battery light came on to see how long it would go (for an amfibian show--no offense to phish and tom marshall fans, but that band just sucked).  It ran for over 2 hours after the low battery indicator came on.  After taking the tape home to listen though, it started distorting at about 1:30 or 1:45 due to the phantom power not getting enough juice I'd imagine.  Anyway, bottom line, if you want to be daring, you can run it until the low battery light comes on and then keep going and change it at the end of the set and you'll still probably be fine.

Doh.....sorry.  Gotta stop posting when I first wake up.
