Topic: 9V Rechargeables for PS-2 and AD-20?

[halleyscomet8]

the power runner comes with several adaptaplugs, but not the 1/8 mini plug that the ps-2 requires. the proper plug can be purchased at radio shack for a few bucks. i power the ps-2 with 1, and the ad20 with another. i have never used over half of the battery life. i have tested it for 8 plus hours, and am very pleased.

Thanks for the info!!

just a question: do the 9v 500Mah lithum batteries require a special charger to be recharged or we can use a normal one?

Or you can get the new Lithium Polymer batteries 500maH

CAUTION - I purchased this bat for use w/ AT853>ST9100>H120 and found that even at full charge they can't power the pre properly (no signal).  I spoke with the supplier and they recommended their MH-9.6v-230.  The Lith-Poly is only rated at 8.4v

I think I'm having the same problem with my sonsosax. I figured it would be OK since the sax can run off 12v, but apparently not off the internals. Damn! They were so nice and lightweight, too.

Has anyone used the 500maH rechargeables successfully with a sax? At first I thought it might be a bad connection, the terminals are a little shorter than a regular duracell...but this looks like a more likely culprit.

Hey I thought I'd chime in on this since I just purchased 40 9v rechargeables and two 10-unit chargers for use at work in a pro-audio situation...

I talked to a really knowledgeable person at thomas distributing about what I wanted them for and that I wanted the longest possible run time. 

He recommended the Tysonic 250 mAh, 9.2 volt battery on this page:
http://www.thomas-distributing.com/9v-rechargeable-batteries.php

The powerex ones are either 8.4 at 300 mAh or 9.6v at 230 mAh.

Some devices don't play nice with 9.6v batteries, and the guy told me that they are a bit longer than your standard 9v which could be a problem for a lot of pro audio uses.

I ended up buying 20 powerex 300 mAh and 20 of the Tysonics.

They run our devices (wireless clear-com communication boxes) for close to the same amount of time...with the Tysonics lasting a little longer.  They still run about 2 hours less than the energizer industrials we used to use, but that's ok in our situation.

I'd recommend the Tysonics.  They are actually 9.2volts, and are more mAh than most others.  Seems like a good balance or voltage and longevity. (and they are about 1/2 the price of the lithiums!)

YMMV and good luck!

hey
I used to
power both of my Ad-20 and PS2
with one 12v Sealed Lead Acid battery
a powersonic  model PS-1230
12 v 3.4 amp hour
I just wired up a splitter with 2 plugs from Radio Shack that fit them both
and an inline fuse... I think may be I had a resistor in (or two) line too, to help regulate the power drain

 after talking with denecke via email
they were very helpful...
I realized and found out that Phantom powering my Rode NT-5's with a 9v cell in it would run for about 35-45 minutes! before horribly degrading
but with this
monster lead acid
I could power both before draining below 7.2 volts
which is where the PS2 and AD-20 have issues
for over 20+ hours

I got a powersonic  PSC-12300A
charger  -  300mA
which is a flaot charger... so it  charges it an d then floats to not over charge or drain it

I then converted this to run my Presonus Firebox
that
I just replaced with a MOTU Ultralite, and may use this system for it

I never had any ground hum.... it always worked fine


so thats  my 2¢

I'd be curious to hear your comparison of the pres in the Presonus vs the MOTU.  I might be biased because I have two Presonus boxes .
