Members Ed Dixon Posted February 23, 2007 Members Share Posted February 23, 2007 I get mine on EBay. Low cost and work well http://stores.ebay.com/Shoreline-Market_W0QQssPageNameZstrkQ3amefsQ3amesstQQtZkm This is what i use: http://cgi.ebay.com/4-9v-250mah-Rechargeable-NiMH-Batteries-battery-NEW_W0QQitemZ9740975076QQihZ008QQcategoryZ50622QQcmdZViewItem Ed Link to comment Share on other sites More sharing options...
CMS Author Craig Vecchione Posted February 23, 2007 CMS Author Share Posted February 23, 2007 None that I've ever used. Battery life is short enough with alkaline cells that I've not chanced the even shorter life of NiCad rechargeables. I doubt they'd make it through a typical 4-5 hour gig, but I'd love to hear of other's favorable experience. Link to comment Share on other sites More sharing options...

CMS Author Craig Vecchione Posted February 23, 2007 CMS Author Share Posted February 23, 2007 Ed, which charger do you use...which IEM's, and how long are these cells lasting in use? That's a really good price for NiMH. Link to comment Share on other sites More sharing options...

Members abzurd Posted February 23, 2007 Members Share Posted February 23, 2007 Which 9v Rechargeable batteries would folks recommend using for iem receivers? For 3 hour use a night - none I've used. It's been about 2 years since I last looked, but at that point, I'd purchased the highest capacity 9V's available and they still petered out about 3 songs from the end of the night in my Shure IEM's (PSM400). Similar results for 9V mics too. AA's and AAA's are a different story. We've had good luck with microphones and guitar/bass wireless with them. There's is already one company making a lithium ion rechargeable 9V. My guess is these will be arriving in the mainstream market shortly and then 9V rechargeables will be ready for prime time. Here's a couple links for you: Lithium ION - they specifically call out wireless microphones in the ad. Note: requires their lithium recharger. You're looking at $50 for one battery and the charger. higher capacity NIMH than I've used in the past so these may be worth a try, especially if you already have a charger Link to comment Share on other sites More sharing options...

That's a really good price for NiMH. I got my charger from same place. Charges 9V in about 14 hours. I Have both Shure PSM200 and Carvin IEM. Batteries tend to last 3-6 hours. I change every 2 sets.

Batteries tend to last 3-6 hours. I change every 2 sets.Ed That's about what I've experienced in a PSM200...about 3 hours, maybe 4 for a 'coppertop' alkaline, so they won't make it through a typical gig without either changing out or worrying about it. But the eventual cost saving would make them well worth the effort of remembering to bug the guys for a changeout at 12:30am:D Link to comment Share on other sites More sharing options...

But the eventual cost saving would make them well worth the effort of remembering to bug the guys for a changeout at 12:30am:D I think the 300 Mah ones might fare OK. One of the factors is that you have to use it within a few days of charging. Even sitting around a week or so will affect the overall capacity a bit. Rechargeables don't hold a full charge that long. The good news is, unless a high profile gig, it's generally not that big a deal to change it at the end of the night if it does peter out. Certainly less critical than using in a wirless microphone.

Members agedhorse Posted February 23, 2007 Members Share Posted February 23, 2007 The average 9V Alkaline battery is about 600mAh, so with a NiCad or NiMH at 250-300mAh, you will get approximately 1/2 the life. If a standard alkaline is barely adequate, the rechargables will not be. Link to comment Share on other sites More sharing options...

If a standard alkaline is barely adequate, the rechargables will not be. I read earlier today that a 9V alkaline is 540 mAh. the New Lithium rechargeables are 500 mAh. They also claim "Will actually out perform a standard 9 volt alkaline battery in High Drain Applications." Duracel Procells give almost 2 shows (6 hours) in Shure PSM400's.
