CA9200 & CA-UBB 9v Battery Duration
« on: December 03, 2013, 01:58:57 PM »
just wanted to know for how many hours both devices can be correctly powered by a 9v alkaline battery (my CA9200 is the 3-wire version with 4.7k mod switch)

I just would like to know a safe point to decide when I need to change batteries...don't want to change them after each show!

I'm going to use these ones: http://data.energizer.com/PDFs/EN22.pdf

Tried with Duracell Procell ones but got some dropout issues on CA9200, I think it's dued to how the connectors are made on those ones and to the fact that they're slightly bigger than the Energizer ones (got no dropout issues with energizer on the tests I made)

thanks for the help

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...

ok. but how many hours CA9200 and CA-UBB can run with a standard 9v alkaline battery?

The 9200 is 10mA the ubb would be much less than 1mA of current draw for the mics. So you should get atleast 30 hours on a battery. Before I would change it. However I do recommend rechargeable batteries to everyone simply because they are cheaper in the long run and less taxing on the environment.

ok...so:

- CA-UBB + 9v standard alkaline 9v battery > about 30 hours
- CA9200 + 9v standard alkaline 9v battery > how many hours???

I was considering those lithium ones you linked above but I read they're a bit bigger than standard 9v and I'd like to be safe with CA9200

Strong endorsement, I may check those out.

Sorry Preamp 30 + hours ubb who knows maybe 70 hours maybe more. I would strongly recommend a volt ohm meter to anyone that uses batteries for shows they depend on they are cheap. My battery box will run down to 6 volts with out any issues for the mics. The preamp will run down to 6.9 volts and still work, with very little distortion. So if you get a volt meter thats your best bet. To measure voltage and see where it is.

Clarifying proper use of the voltmeter for doing this- to get an accurate reading, you want to measure the voltage across the battery's terminals while the battery is in-use in the device, not with the battery out of the circuit by itself.

Not sure about the 9200, but last year this time I ran batt tests with an Energizer MAX 9v Alkaline in my 9100 and got around 75 hours ;) 8) So even if you get HALF that, you're good to go 8)

This question about battery life has been asked many times and a while back Mr Church said he'd be carrying out formal tests, but I can't find any link I'm afraid.  FWIW, I think these things should be ascertained during development so the data is available when buying.

The 9100 draws twice the current of the 9200.

I would go by battery voltage when it runs down to 6.8 volts it's time to change the battery I would actually change it around 7.4 volts.

So the 9200 *SHOULD* get over 100 hours then ;)

Chris speaks the truth here.  Never let your 9V battery powering mics run less than 6.8V because that'll be bad news (I know this from my previous job in TV doing audio for a 24-hours news channel).  ;)

There is no "number" because it depends on how hard your driving the preamp.  At the end of the day, I replace my 9V battery every 10-12 shows (assuming 2-3 hours for each), that's under 40 hours.  I'm not gonna cheap out on batteries especially if it means I lose a recording.

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 ;)

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 ;)

Re: CA9200 & CA-UBB 9v Battery Duration
« Reply #27 on: December 12, 2013, 03:41:17 AM »
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.

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...

Trust me fellas, Id MUCH RATHER use rechargeables 9v, but Jon/Naiant said specifically told me NOT to use them with my 9v LB because the voltage would be too low. So I buy 8/packs of Energizer MAX 9v at Sams Club every so often, and get 3 shows per 9v, as said above. I HATE buying Alkaline 9vs, but at least I get the MAX capacity out of them doing 3 shows per battery! Its still MUCH BETTER than my old LemoSax. That sucker used 2x9v PER SHOW :( Thats one of the reasons I sold it. But Im glad I did, because I like Schoeps>LB[OT] better than my old Schoeps>Sax tapes 8)

anr, Chris has a spec at 10mA, it's just simple math from there.  The runtimes are going to be long enough that you won't be able to easily track battery life.  The battery box life is practically forever.  Buy a $9 battery tester or a multimeter.  When the 9V gets to 7V, stop using it.

I put specs on my site but not too many people read them anyway.  A littlebox is much higher draw than Chris' amps, so you can't use rechargeables *with phantom mics* because of their higher internal resistance.

Bean, you might be OK on low power with a rechargeable + KCY, but you won't get the same runtime as an alkaline.  That setup is much lower draw than phantom mics.

Really? Thats great news Jon 8) I would keep the Energizer 9v Alkalines for festies and thats it! Id LOVE to be able to get some rechargeable 9vs for my LB!

So, is that charger that comes with those batts Chris linked for us, a "smart" charger or just a decent charger? I NEED something thats very reliable :) Like as reliable as AA/AAA rechargeable batts/chargers :)

Thanks,
Bean

These are lithium ion batteries do not USE any other charger than one designed for these batteries and it works fine I use it all the time. If you ever try to charge lithium ion batteries in a regular charger you are in for a very nasty surprise! Do not do it.
