Boomboom Posted April 9, 2014 Report Share Posted April 9, 2014 Hi, I've been looking at threads regarding what rechargeable batteries to use and not to use with UCR411s and I'd like a definite answer (if that can exist) about what models to use and what to avoid please ? In this thread (link below), it's stated that recent Tenergy ones are to avoid... but what about the iPower ones ? Lots of people use'em in the transmitter but in the receivers ? What running time do you get ? (ok, can't paste nothing here anymore... so the title of the thread was ''new iPower 9v alternative from Tenergy'' ) Thanks Quote Link to comment Share on other sites More sharing options...
Jon Gilbert Posted April 9, 2014 Report Share Posted April 9, 2014 Ipower all the way for me, they last long enough that I've never felt the need to worry about it! Quote Link to comment Share on other sites More sharing options...
RPSharman Posted April 9, 2014 Report Share Posted April 9, 2014 I have used iPower in 411s many times. No issues. Good run time. Not sure how much time, but several hours if I remember correctly. Quote Link to comment Share on other sites More sharing options...

Boomboom Posted April 9, 2014 Author Report Share Posted April 9, 2014 Thanks a lot ! On another forum I get ''something like 4 hours'' with brand new batts ... well... It's a shame cause you get so much more runtime with non-rechargeable ones but I want to use rechargeables... It's encouraging I get more positive comments on this side of the web; a middle point between all the comments I gather would yield something not too bad ! I might in fact be able to change once in a job day at lunch. I know it's quite uncommon since we mainly use the SRseries nowadays, but I was affraid I'd get like two hours...

Jon Gilbert Posted April 9, 2014 Report Share Posted April 9, 2014 You'll get a lot more than 4 hours. Quote Link to comment Share on other sites More sharing options...

MatthewFreedAudio Posted April 11, 2014 Report Share Posted April 11, 2014 I've been using HiTech 9V lithium-polymer 720mAh batteries in a bunch of UM400a transmitters and I get 8-9 hours of run time per battery.

Jon Gilbert Posted April 11, 2014 Report Share Posted April 11, 2014 I might try some of those HiTechs for an upcoming job, might be just the job for my UM450s Quote Link to comment Share on other sites More sharing options...
LarryF Posted April 11, 2014 Report Share Posted April 11, 2014 The iPower batteries typically run units longer than an alkaline 9 Volt. They occasionally have trouble with RF in a transmitter. The unit will try to turn on and when the RF comes up, the protection circuit in the iPower will shut the battery down. Not always but often enough to be a pain. They seem to be ideal in receivers.

" not so " I'd like a definite answer (if that can exist) about what models to use and what to avoid " it depends... and that is definite! actually, while some folks have had Tenergy issues, others have not... and there are way too many variables (like chemistry, and capacity) and thus YMMV, and I use what seems like the best idea for the gig at hand... definitely avoid the batteries in 9V form factor but with only ~7.2 V potential Quote Link to comment Share on other sites More sharing options...

Best Regards, Larry Fisher Lectrosonics My personal experience with this and ipower has been strictly with plug on transmitters only. I use alkaline in plug on transmitters only. All other 400 and 400a transmitter beltpack versions as well as 411's have worked splendid for me with ipower batts Ken Quote Link to comment Share on other sites More sharing options...
Michael Panfeld Posted April 21, 2014 Report Share Posted April 21, 2014 +1 on the Hi-Techs. However, I am getting 10.5 to 11 hours in a 411 or Um400a. P.S. I like how the 2 batts in the 411 have an almost identical runtime as 1 batt in a UM400a. Cheers to Lectro's engineering department. Quote Link to comment Share on other sites More sharing options...
soundtrane Posted April 21, 2014 Report Share Posted April 21, 2014 Is anyone still using those Soshines that were the hip thing a few months ago?

johnpaul215 Posted April 21, 2014 Report Share Posted April 21, 2014 In my experience iPower run time was a little better than ProCell Alkalines. That goes for a transmitter or receiver. iPowers are great to power a 411 mounted on a little camera. Sure, not the runtime of a disposable lithium, but how often do you need a 16 hour run time? Sure, there are times you might, but not on most of my jobs. Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted April 21, 2014 Report Share Posted April 21, 2014 9v iPowers work fine for me in 411s. I may or may not swap them @ lunch depending on the run time so far that day. Almost weightless, nice when you have a lot of RX in the bag. philp Quote Link to comment Share on other sites More sharing options...

Best Regards, Larry Fisher Lectrosonics I've never run into this problem, and I've been using iPowers with UM400s, UM400As and UH400As for what seems like an eternity.
