Call me stupid, but I do not re-use a 9v battery ever after a show. Instead I use them in my meier headphone amp until they die. I always use a fresh 9v battery in my battery box every show cos I dont want the hassle of fussing about loss of power. Yeah stupid I know  ;D

That might be a touch OCD/overkill, however, it's better than running a 9V into the ground.  :)

I don't think it's stupid at all.  If you buy a battery powered device and the manufacturer won't or can't tell you how long it will last, then for peace of mind change it after every use.

Or you could just sacrifice a couple batteries and do an actual battery runtime test ;) It's the ONLY way to know for sure. For instance, my 9v LB lasts 18 hours on a single Energizer MAX 9v. Therefore, it lasts about 3 shows!!! I keep a small piece of painters tape on that 9v battery and after each show I write on the battery how many hours it's been used so far. So since doing that, I can EASILY record 3 shows with that single 9v battery ;) 8)

Well I ran my ca14>9100>m10 run times while I was recording realistic levels in front of the Tv cranked! These folks just need to sacrifice a couple batteries and see for themselves how long each of their setups runs on power. Why guess and use a new battery every night of recording? it's a HUGE waste of money and it's not too GREEN either ;)

If 18 hours = 3 shows, you're going to some shows! ;D

Bean, you missed my point.  I think any design engineer should (a) have a specification he wants his design to work to and (b) will verify the design works to specification before advertising and selling it.  For a start, what are the buyer's rights, if any, if he finds his own testing doesn't meet with his expectations?   But, if you're prepared to accept such laziness, then your suggestion to sacrifice a couple of batteries is perfectly fine.  I'd just prefer to have a manufacturer's spec sheet to compare my result with.

Dude I am not lazy I am just busy, I have lots of orders to fill and I do everything. I already stated what the current draw is of 10mA At full gain. For the ca-9200 and 18mA for the ca-9100. What more do you want? I cant specify what every type of battery is going to have for run time in my product without knowing the mah of the battery.... :) Obviously right? Lazy really???? I dont have 80 + hours to do a real world test to tie up my gear and my computer to do a long running test. I dont have that time right now. I am HARDLY an electronics engineer. Just a guy making some great products for the community. At great prices. I dont see you stepping up and making anything. I would love to see how you handle my work load. Never call someone you dont know lazy it makes you look like a total ass. I have the ability and the equipment to do long term real world testing of a battery trust me. I have given you the current draw of the device and the minimum voltage it should be run at. By the way thats way more than most companies that make audio gear give you. Anyone that says 80 hours and just gives you some blind quote is misleading you. Because there are so many factors that go into discharge rates in a device its 100% impossible to give a perfectly accurate rate for all temperatures and all conditions. In any event I do my best to provide good gear at great prices. I dont see too many people here complaining about my gear do you? So I guess I must be doing something right! Oh by the way here is my little test bench I guess I have the ability to do a battery test what do you think?

I simply refer you to the various threads over the years asking the same question.  On one occasion, last year, you're reply was you were about to conduct testing.  If you had done that, and published the results, providing a link would have been a suitable reply to this latest thread.  The fact remains YOU said you were going to conduct this testing, and it seems more than myself eagerly await the results.  But of course you are at liberty to run your business the way you see fit and I continue to value my Church Audio mics.

According to duracell the MAH of a standard copper top battery is 580 mah. So at 10mA current draw = 41 hours approximately. So 41 hours for my 9200 and UGLY 2 So for a 20 mA draw like my 9100 and Ugly 21 hours approximately. For my Ubb battery box at lets say 1mA of current 406 hours. BUT again this is only a calculation based on a temperature of 65 degrees F and with a mAh of 580 mha of a Alkaline 9volt Duracell copper top battery.
Assuming 70% capacity remaining on the battery. So 6.72 volts remaining on a standard 9.6v.

Well, you figure you get to show and setup around 8pm, and you teardown and leave around 2am, so thats 6 hours right there. Plus, if there are breaks between bands I just leave my LBs powered ON ;) I did 2 shows on my current 9v Energize MAX battery, and Ive only used up 11 hours, and thats being VERY CONSERVATIVE ;) So I have 7 hours left on my battery for the next show to record ;)

I wish I could start using Rechargeable 9v NIMH Batteries, but Jon[Naiant] suggested thats not a good idea at all, because of their lower capacity and some othe technical stuff I didnt understand ;) 8) I get 18 hours on my LB w/ my Schoeps caps because I run the LB on LOW power. When I run the 9v LB at HIGH power, I only get 6 hours, compared to the 18 hours I get  on LOW power.

To the OP, Im sorry about the thread highjack, just wanted to make things clear ;)

And like Ive said it the past, I used a few Energizer MAX 9v batteries when I ran battery runtimes with my old 9100, and I got 75 hours ;)

What your mixed up about is, not EVERY battery is the same. I would just recommend buying a 2-pack of Energizer MAX 9vs and see for yourself. Just set your gear about 6" from your TV and make sure your levels are peaking around -12 to -6 MAX :) I do runtime tests EVERY year right before festie season, and I cycle my AA/AAA batteries AT LEAST every few months to keep them in tip top shape. My 2300mah Energizer AAs have been running SMOOTHLY[knock on wood 8) ]and they are still at about 90% of their capacity after 3-4 years!

So do some runtimes yourself and report back to us ;)

Happy Holidays!!!

I just use Imedion 9.6 Volt low self discharge NiMh rechargeable batteries and never need to worry about any of this crap. I recharge every couple of shows just to be safe. I believe Chris Church has recommended using batteries such as this one.

9 volt batteries are too expensive to have to replace them well before they probably will run out to avoid the chance of a disaster. I would never use anything but rechargeables.

Chris made a new recommendation earlier in the thread for a rechargable '9V' with a higher capacity than that of the 9.6 Maha [quoted below].  I use the Mahas in my CA-UGLY Preamps powering DPA 4060s and they've worked very well.  I have no worries running them for about 12hrs straight, they will probably go a good bit longer than that but I change them at 12hrs to be safe.  I recharge them between each use.

9v battery connectors have to always be sinched tight with a pair of needle nose pliers. The best battery I have found so far is this one They are DIRT cheap and seem to run for atleast 2 x longer than the Maha 9.6 these are lower voltage around 8.7 but they are 600Mah batteries!!!! They are twice the ampacity of normal 9 volt batteries. And Like I said they are cheap....  Oh yeah the link...
