Rechargeable Batteries

Last week, someone asked Bob Kauflin a question about using rechargeable batteries in wireless microphones. In his response, he referenced part of the Covenant Life Production Team's most recent monthly update. Go ahead and read his whole post.

Not surprisingly, my readership quadruples whenever Bob kindly references my meager blog, as he does occasionally and always with much encouragement. Thanks, Bob, for your kind words and for sending some of your friends in my direction. I'm praying for you and your book!

I wanted to add a few thoughts for those of you who happened to read Bob's post, in order to put it into context. First, Covenant Life only recently began recycling batteries at all. That change prompted me to reconsider the way we handle batteries on the tech teams in an attempt to utilize the new option of recycling. At the same time, I decided to try to use our batteries more fully before throwing them away.

Please know that there are other churches that do it much better. For instance, one of my volunteers mentioned visiting a church that has four (or more?) containers for batteries: Full, 75% 50%, and Recycle. They use a battery tester to determine which bin the batteries go in, and they have certain uses for the different levels of batteries. If you are able to manage this more complex process, I'd highly recommend it, since it will lead to even better stewardship.

Finally, I'm grateful for Bob Kauflin's wise pastoring, even in very practical areas like batteries. He wrote:
We have two priorities in tension here. The first is to be wise stewards of the resources God has given us. The second is to faithfully serve congregational worship and the preaching of God's Word. Ultimately, the second concern is the greater priority.
Let's make it our aim to be wise stewards without compromising the effectiveness of the preaching of God's Word.

Great post! Even as a smaller church, (somewhat under 500) we were PLOWING through 9 volt batteries in our first generation Sennheiser ew100's. Not only are they maybe three bucks a pop, they just didn't last more than a day. Needless to say, we were really stoked to get our second generation ew100, which takes AA's, and they seem to go on, and on, and on, and on...

Okay, that was lame, I know, but batteries seem to be a huge chunk of our recurring expenses, and I just assumed it was an operational "cost of doing business".

Anyway, I'm going to leave a multi-tester in the sound booth and designate a box for practice batteries.

Great blog BTW!

I was the one who asked about the batteries, and as I mentioned in my comment on Bob's blog, thank you so much for your insight on this issue. I've been a subscriber to your blog for a few months and the issues and topics you bring up about serving through behind-the-scenes technical ministry are very helpful and useful. Keep up the great work, and may God continue to bless the things you are doing in your ministry.

Just for my own information, why wireless instead of wired? Any benefits other than not having wires laying around? What would be the difference in your services if you went wired?

Thanks for the blog and all. Very informative.

God bless your ministry.

Why wireless instead of wired? That is a great question. We have had different reasons for going to wireless mics and in-ears at different points. Some of them have proven to make sense in the long run. Some of them haven't. I'll probably post something more extensive later, but here are a few quick answers:

1. Stage neatness
2. The ability to remove certain things from the stage quickly
3.Mobility for expressive singers.
4.The professionalism of having in-ears in your ears before you get out on stage.
5. Dramatic readings and such which require freedom for hand movement.

More later...

I agree with what you are saying in regards to NiCd batteries. However the Nickle metal Hydroxide batteries that we use are not as wastefull, but can be harder on the environment. Also these batteries are lasting longer than the alkaline ones that we were using in the past. In fact we go at least 3 weeks or at least 5 hours on one nine volt battery of the NiMhd batteries.

You do bring up a good point, we should have a battery bin to place the rechargeable batteries in once they go bad.
