AA Batteries
 
What will drive my senn wireless lav mic's longer, Rechargable AA's or regular Energizer/Duracels?

NEVER use rechargeables in a wireless system.
Go to Costco or Sams Club and buy the huge packages of 50 AA's. Cheap, and well worth it.
Some wireless systems won't warrant their gear if you use rechargeables.

Not only can you use NiMH AA rechargables with the G2, Sennheiser even has recargable battery packs available for them (but why go proprietary?).

We aren't talking about NiCads here, which are obsolete. NiMH rechargables actually are capable of holding MORE power and sending MORE current than alkalines are. The only place I'd advise using something else is in extreme cold weather, where you're better off with lithium batteries that aren't as affected by it as either alkalines or NiMH.

Definitely get AT LEAST 1800 mAh batteries minimum. I believe the current top batteries are 2300 mAh, but it could be even higher now, as it seems to go up every few months.

I ran a pair of 2000 mAh batteries in my G2 lav transmitter for 6 straight hours and still had plenty of juice left (batt indicator was still full, and the batteries went into my cordless mouse, which ran for a week off the remaining charge).

Things change, DSE.

i'm with doug on this one, i have yet to use a rechargable i trust, they seem to die down pretty quick even though they down't completely die, nothing like the smell of fresh batteries...

I realize the G2 allows hydride batteries. I've also experienced problems in 3 different venues with the G2. I'm amazingly unimpressed with this overhyped wireless.
Of course things change. I get more airtime out of my laptops than ever before, more airtime out of my com units than ever before, etc, etc. and those are all rechargeables.
If anything, I'm far from being a Luddite.
I stand by what I said earlier, some wireless companies will not warrant or support their systems if rechargeables are used.
If you want to take the risk of the batteries gaining memory, and they all do, or the leaks that rechargeables are often known for, go for it. Losing audio signal during a shoot is a little more traumatic than having my laptop battery die when flying.
On the other hand, I'll follow what has always worked for me, and is still the standard of large format production houses and broadcast stations. Alkaline.

I use rechargable AAs in my Mouse - PERIOD!

Bryan Beasleigh October 22nd, 2004 09:55 AM

I have about 100 or so AA cells on my shelf and they're cheap. I can't be bothered playing with rechargeables especially for what the disposable alkalines cost.

Jonathan Gentry November 1st, 2004 09:38 PM

OK... I'm adding up the post count tally on this issue and I guess I stick with my disposables. Thanks for the help. I recently saw the 2500mah rechargables and thought that was pretty strong though...

NiMH & Wireless (radio) microphones
 
I have done some extensive testing of NiMH batteries with Sennheiser, AKG & Sony wireless mic's. The results can be viewed on my website at http://www.soundandmusicco.com/nimh.htm

John Hartney October 18th, 2005 12:38 PM

I've been using NiMh in all my Sony wrt series wireless, Beyer U400 wireless, wendt mixers, HHB md500, etc... all my field production gear for several years. For me, it is an environmental matter, alkalines generate a lot of waste and should be dispossed of properly - to a hazardous waste company. NiMh chemistry is a green product.

I keep alkalines for backup in the kit, but have never gone to them.

Of course, batteries are removed and charged daily, but I'd be replacing alkalines, too. They have an in service date, device, and order number written on them and are rotated out before the charge drop gets to be an issue. I've had more problems with Durecell alkalines leaking than I've had with high quality NiMh cells.

[slightly off subject] run-time problems? ...or other? Just currious because I've not heard too many critics with this piece of hardware.

Wow! There is an old thread regurgitated. :-)

Before this system was released, there was a great number of anticipatory posts, so upon arrival at the DC Convention Center, and knowing that they'd just installed these, I was expecting great things. I couldn't even move halfway through an airwall with this system. As I'd mentioned in other posts, it might be that they hadn't set these up yet. Ironically, I'll be back in those same rooms in a couple weeks, I'll report again if anyone is interested.
Aside from the distance/interference problems, I also didn't care for the sound when levels were really pushed. I have a loud voice, and didn't care for the way the companding system reduced the bottom end and shrilled out the top end.

Lithium batteries last a lot longer than alkalines
and give about 1.7 or 1.8 volts. I used them in
a flash gun and it cut the recycle time in half
(15 seconds to 7 seconds) as compared to alkalines.

John Hartney October 21st, 2005 07:42 PM

"regurgitated" we'll never hear that used again referring to a question about audio related hardware... but sometimes, that's all a little eagle can digest, so it must be.

Did I miss something in this post John? This thread was 11 months old before it popped up again. "Regurgitated" would be the correct word for an old thread resurfacing, or maybe my English is weak?
