I just completed a review for EventDV Magazine on my experiences with the Sennheiser G3, rechargeable batteries, and battery chargers. Watch for it online or in the January EventDV Magazine. For the review I tested seven battery options, including the new Ansmann Max E 2,500 NiMH low self discharge batteries. They were my top pick. I learned a lot about the differences between the discharge curve of alkaline batteries and NiMH batteries and this difference explains why rechargeable batteries don't appear to last as long when you look at the bar remaining indicators on the Sennheiser wireless body-packs.

I fully trust them to make it through a full musical with intermission (having batteries in place an hour before the show starts). Usually the 3 bar battery indicators still have 2 bars when I take the batteries out 4 to 4 1/2 hours after putting them in...a couple might have gone to 1 bar, but none have died. I figure even though the box says they'll last for 1000 charges and they won't get that many in one year, to be safe I'll just replace them every year from here on out and give the old ones to cast members who can use them, keeping a few for myself. This is saving us $1000's and makes me feel better...glad to not be throwing away dozens of batteries every night.
