I've been using Maha PowerEx 2700mAh NiMH AA's in the Edirol R4-Pro, this lasts 4-5 hours before swapping batteries. In the G2's I use them as well and they work just fine, no difference in audio quality compared to alkalines. Forget average life in the G2's, think I swap em once a day. Also, I always use a one hour charger. my $0.02
cheers

I have been using the Rayovac Hybrids. Runs my G2s at least 10 hours without powering down. Even holds the charge when unused 70 -80% or more than normal NiMHs. I was going to buy the DC power adapter for the receivers and power externally, but with that kind of battery economy it wasn't worth the expense or trouble.

Rechargeable batteries loose power the more you use them. The more you use them the less they hold a charge. Allot of electronics manufacturers specify that you not use rechargeable batteries and run only fresh alkaline batteries.

Unlike my Lectro receivers that eat 9Vs two at a time, which makes external power almost a necessity.

King of the Hill: Energizer AA Lithiums.

Pro: Last about 3 times longer than anything else, 40% lighter in weight, 10 year shelf life.
Con: cost a lot

I've been using the powerex 2700's on my G-2's. They run all day and barely dent the battery meter.

Sennheiser sell a set of NiMH batteries for use in the G2 kits. Needless to say they are expensive, no different to other NiMH batteries and you need their charger to charge them as they're in a plastic housing.

Keep in mind that the high capacity NiMH cells have a high self discharge rate of around 1% per day. If this is an issue Sanyo and a few others make 2100mAH cells designed for remote controls with a very low self discharge.

We have found that the hand held Senny wireless mics will not work with NiMH batteries.

Well if you're investing in NiMH batteries, you should also be investing in a charger that has options. Look up the Maha / Powerex MH-C9000. It's the best way to keep your batteries healthy.

I had Energizer 2500NiMH batteries that would only work for about 2 hours in an SMa transmitter. I did a refresh and analyze, and now I get almost 4 hours.

I have not tried the Rayovacs in the Senny H/H. I do get about the same economy in the butt-plug configuration with a dynamic mic.

Just a word from a Network and Major Studio viewpoint. You will NEVER see rechargables being used on a production. We used to use Duracell Procells until lately purchasing must have gotten a deal for Energizer Industrial batteries. Peoples jobs are too important to rely on rechargables....

Kevin Fox · March 30th, 2009, 10:06 AM

I'll back up what George (and others) said. We have 4 Sens HH, 2 Sens Lav, 2 Shure HH, and sometimes Lectros (rented) we use on stage for our audio company. We also do system installs. We NEVER use recharg-o's and recommend to all clients we install systems for to follow the same advice.

BTW: Mic problems from recharg-o's falls into the top ten reasons for service calls on systems! (Fortunately it's an easy fix).

Just my 2 cents...

John Willett · March 30th, 2009, 10:17 AM

The only batteries you should use in a G2 are standard alkaline AA size (eg: Duracell or ProCell) or the Sennheiser BA 2015 rechargeable pack.

You should *not* use standard AA rechargeables.

The BA 2015 has three contact points and "talks" to the transmitter or receiver.

I don't think he meant damage.. just meant they are the cause of issues that stem from the use of rechargeables.
