OldGit Posted March 17, 2008 Share Posted March 17, 2008 After a particularly large amount of troublesome popping and crunching from our PA on Saturday we finally tracked it to one of the wireless mics. It had a rechargeable 9v battery in it (a new, fully charged one) Our drummer has turned up this article about not using rechargeable batteries in wireless mics .. [url="http://www.wirelessmic.net/wireless_rechargeable.html"]http://www.wirelessmic.net/wireless_rechargeable.html[/url] However it's undated so does this still apply or are new rechargeables better? Any views? Thanks, OG Quote Link to comment Share on other sites More sharing options...

Outstanding. Consider a trade for mid 60's White Lightning pickled model? Will deliver. Sounds Plausible. Could the battery problem be related to the older NiCd cells? Newer NiMh / Li cells should have less memory. Or would a disposable fit and change it before every gig? Good luck. Quote Link to comment Share on other sites More sharing options...

dudewheresmybass Posted March 17, 2008 Share Posted March 17, 2008 we use Li cells in all of our wirelss systems (around 10 -14 at a time!) never had a problem. However they are pretty expensive to buy initially though! Quote Link to comment Share on other sites More sharing options...

NiCads used to suffer from the memory effect but IIRC they were developed to the point of not suffering. NiMHs and whatever other rechargeable stuff is out there doesn't. I've used rechargeables in my wireless for years. No problems. I put one charged one where I can get to it easily so I can swap if necessary. Normally get through a 2.5ish hour set with one. Kaz is using rechargeables in her wireless mic, again we keep one spare easy to hand but one charged one normally lasts for a four hour barn dance.

stevebasshead Posted March 17, 2008 Share Posted March 17, 2008 If it helps I use rechargeables in my AKG bug transmitters (2 of). I'd easily get 3 gigs out of them but to be 100% safe I just leave the transmitters on after each gig to drain the batteries by the morning. Then they get charged from an uncharged state and I know for sure they'll do the next gig. I've got a spare pair which I alternate with so I've always got one pair in use and one pair charged and ready to go for the next nights gig. Never ever had a problem. I also carry a pair of disposables just in case. I was a rubbish boy scout but the phrase "be prepared" seems to have stuck!!... Quote Link to comment Share on other sites More sharing options...
