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.
.. and diggin your appropriately descriptive term- 'ampacity'.

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.
