Topic: R-09 battery life with 2700mAh NiMH? (Updated with battery comparison)

Yea... That is what I ment.... I've seen a few threads here that say 8 is basically unity and the level you start applying gain.  I've seen a few others that don't agree with this.  All I know is that with my SS Setup so far any where from 9-15 depending on the show seems to get me to comfortable 24bit levels.

8 = unity is a myth!

can you recharge rechargable batterys within the r-09 or must you always have a pair handy?

Use separate charger.

I might be wrong, but I don't think the battery consumption is related to the bit/sampling rate you use. Even more when there are no mechanical parts involved.

They are more related to headphone current demands, phantom power and LEDs on.

Does the manual specify anything on that point?

Once again: we badly need someone who do serious tests on the H4. with measured data and all.

I feel you have a point about recording mode, indicators, and phantom power having effect on battery life, likely ONLY phantom power being used or not and for how much power the connected mic is drawing is significant in making real difference in length of recording time.

No manual so far seems to offer any information on specific power demands with deck modes.

While I have yet to do a review of the new Zoom H4, while doing the bench tests for the reviews of MT and R-04 on my site, I didn't notice significant power changes with recording modes or indications. 

The H4 is quite different from those two decks in having an extensive 'effects' function that may change power in a more significant way, but as mentioned, somebody needs to measure this and post the results.

That's very unusual, isn't it?

In any case we should thank cellular phones research that gave us NimH batteries, who are really a great working horse:  eats very little and plows a lot. NimHs can let you use unsophisticated chargers, do not contaminate and are not memory prone as Nicads were.

I wonder if a Li-Ion battery in AA form would do a better job, if there's such a thing yet, but it would need a specific charger.

What bench tests can you perform? Which is your site?

I do not think they will.

24/96 writes to memory or disk far more often than 16/44..  So there is usually a difference in power consumption. For the 722 it is documented in the manual.
