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

Anybody use these?  How are they?  They are only 150 mAH so I don't know if they are worth buying or not.  I know there are a ton of other options for powering these, but I'm a technoidiot and if it's not something I can buy, take out of the box and use, it's not for me.  DIY jobs will result in my apartment being burnt down :)

I'm always paranoid about my PS-2 and/or AD-20 dying so I know I don't get nearly all the juice out of each battery (and 9Vs aren't cheap) so something like this that I could charge up the day of the show and then use that night and repeat for the next show sounds ideal.

I found early on that I couldn't trust a single 9v to last an entire set, let alone the whole night, so I picked up 6 of these rechargeables (and a charger):

I don't have a link, but then I bought a battery box that accomodates six 9v's and has two plugs that I can connect to both the PS-2 and AD-20...now I have no concerns about power failure. I just replaced the six rechargeables after a year and hundreds of recharge cycles.

Thomas-Distributing has always been quick and they have deals from time to time...got a free caller ID when I bought the charger.

Just about the same cost and almost twice the run time.

 I would think, for the purposes of charging the PS-2 and AD-20 for a few hours, that this battery is overkill...Is it really worth the extra five bucks per battery if you're getting the same from a cheaper battery?

since a 9v alkaline batteries are rated at 570mah, paying extra for a 500mah rechargable is likely a good deal.  When using a ps2 with power-hungry mbho 603a/ka200n mics, I'd be lucky to get 2 hours out of a 9v alkaline battery . . . .

I measured the current draw of (2) MSH-1A's on the PS-2 with a 9v alkaline battery. I got 130 mA. That's a lot to ask of a typical 9v Alkaline battery that rates around 500 mA? That Energizer rechargeable rates at 150 mA.

130 mAh draw only gives you about an hour with the Energizer rechargeable. I built some (8) AA NiMH 2250 mAh battery packs that I use with the PS-2 now. I did a test on Sunday and got 7+ hours before the red light came on. I didn't test it any further, because I think the regulator drops out when the red light comers on.

I dunno it's up to you.  I've found that with all the money and time that I spend to get to the show and get it on tape, I prefer to have an overkill in the battery department for peace of mind.  Dead batteries suck!  In the past the 9V Rechargables have been un-useable.  I haven't tried the 400's posted above nor the 500's but a 25% increase in capacity is nothing to scoff at.
Yes, but what do you HEAR?

Wow, this weekend I got about 4 hours out of a single 9V Energizer powering my Superlux's.  I set up by the SBD and would just hit record and know that I had 3 hours on the CJB3 so I'd go back to my seats and then just redo it between sets.  140min for Guster (including time between sets), 95 for Ray Lamontagne and about 20 min worth of Rouge Wave.

I got my PS-2 used from here and it had the commom problem of the low battery light always staying on (I think it's a reversed polarity thing or something) so that's why I want to find a no-worry solution as I have no clue when it's going to die.

This looks like the highest capacity of regular 9V shaped rechargeables.  Maybe I'll pick up 4 so I have a spare set for shows.

ive got 4 200mah 9v powermax rechargeable and get @ 3 hours or so from each batt in the ps2 and about 3.5-4 hrs in the ad20.....they dont last as long as the regular alkalines but after several uses it pays you back....i dont mind using them and for the standard 2.5 hr show they are perfect....also a few alkalines in your bag and you have a decent amount of hours to run at festies without paying out the ass for more batts....the 4 batts and the smart charger werent the cheapest, but i use the batts in other devices as well so for me the cost was fine.....the box from soundprofessionals powers both ps2/ad20 and is supposed to extend the run time by alot, but its not cheap either....

last thursday i had to pull a battery swap in mid set. it was done in less than 3 seconds, but there was still a noticeable dropout. so i have moved to the external power runner batteries. i am doing a test now and have been running for 6+ hours with the levels cranked and the battery lights still show 3 of 4 ;D. i will never have to buy 9 volts again. my iriver h-120 is almost dead and it has the same 6+ hours. i was hoping it would record longer ^-^ oh well

Do you get a ground loop humm connecting the PS-2 and AD-20 to the same battery?
I can't power the PS-2 with the same battery I use for my DAT deck without a ground loop.

in the picture each battery is powering one device (ps-2 & ad20). i am at 7 1/2 hours still with 3/4 power on both batteries

I did a test with just an (8) AA NiMH 2250 mAh pack this weekend and got 7+ hours before the light came on.
I have lots of the AA NiMH cells, as I also use them for my PMD671 too.

Bump for a question.
I see the Power Runner pictured in this thread....does it come with the proper connector for the ps-2?  Does modification need to be done?  Doesn't the ps-2 take a mono mini plug?
Thanks for any help you folks can provide.  I'm tired of replacing 9v cells all the time.
