Topic: 722 battery

[tapernateva]

hey all i did a run yesterday with the 6600 bateery for the 722
i ran my akg460s directly into my 722 and recorded nothing just house noise and me on ts
(will post on etree when i have flact the file)
anyway the point was to test the batteries
i got
9hours with one (file was saved and machine shut down)
i went to bed after starting the other and it jsut eneded
11hrs later verified by file times
anyway hope this helps
all of you

i will try the stcok battery next week
but remember
not alll batteries run the same and all results may vary

did you cycle the batteries

What  Sample/bit setting....light on or off...LED brightness?

These things all affect the power consumption of the 722.

If we're going to compare battery run times, we need to have a standard for everyone to use to compare their batts.

I suggest this:

Sample / bit  96/24

light on

meter LEDs dimmest setting

phantom on

mediia: HDD

unit actually recording with some input signal

If we all use the same parameters for testing, the comparisons will have more meaning.

mitch used basically what you said in your post ran levels at peak and had headphones with volume polus 10 attached
24/96
and lights on 100%

[F.O.Bean]

there is not gonna be any standard unless we all use the same mics, every mic uses more current, the 480's are rated a 2ma, the 414's are 4ma, so thats half the life of the battery right there

cool, i believe the 480/460 both suck down 2ma, so that means i will get pretty decent runtimes as well

i used to get  10 hrs easily going 480>v3(phantom/ansr/aes and spdif active/etc) going into my v3

wow! i don't want to sound like negative nancy but those runtimes seem unreal. i know most people were getting around 5-6 hours with the 6000mAh batteries. i was getting 6 1/2 or so in really hot coniditions this weekend running line in. i need to run some similar tests to verify.

[tapernateva]

possible the batt ran forever since it was only recording silence?!?

[terrapinj]

anyone done any playback tests for battery life?

i would think it would get much better run times playing back as opposed to recording but found that the playback I have done drains the battery almost as quickly. just curious if anyone has done any actual tests.

i'll posdt mine in a short while, i tested out a 6000mah battery last nite, gonna do another test w/ it tonight, thewn the next two days im gonna test a 6800mah one i got

[F.O.Bean]

i got about 6.5 hrs on my 722 running mic-in, low gain, phantom on, BUT i didnt have the backlight on most of the time, im running the test again now w/ backlight on to see and levels were set to near-concert levels

and FWIW, this is w/ a 6000mah battery

Hi Nate,
 
We recently ran some tests with the Sony NP-F970 battery (6600 mAh) with great results. Powering one condenser microphone while recording to the hard drive, the Sony battery achieved a total of 7 hours of continuous record time when fully charged.
