Rechargeable 9volts for wireless use Can't Post

We use Lectrosonics wireless systems and go through a large amount of batteries per year. I noticed on the Lectrosonics site that they recommend, and even ship with one of their models, the Li Ion Polymer battery system. They have done comparison tests and found a 20% longer runtime with their UM400 transmitter than with the recommended Eveready alkalines. I'm not doubting their findings, but would like to hear if anyone has used these batteries in the field and what their view of them is.

Jan, get them.
I have been using the 9-volt polymers (8 of them, sets of wireless and mics) for over a year now, and they work as advertised.

I used to use them with my Samson Micro32 wireless system (I now use Sennheiser which take AA's), and I could run my wireless all day long 8-10+ hours. Since I use wireless all day long, normal ceremony use as well as board or mic feeds to my camera for receotion work, with normal 9-volts I would always have to change out my batteries at least once during the day.

They are expensive, but worth the price if you ask me, especially since they are rechargeable, so it saves you money in the long run.
BTW, since I don't really use the Samson's anymore, I still use the batteries with my Rode mics, which of course run forever on these little babies.

Michael,
Do you know where those batteries are being manufactured? I had a bad experience with both a 9 volt & AA rechargeable battery at the same gig and I vowed to never use any small-type rechargeable EVER again. I was not surprised to discover the problems batteries were manufactured in China...the land of junk. Mad
