I'm the sound man at our church and we just recently upgraded the wireless mic system to the Shure ULX-P system. I've been looking for a rechargeable 9V battery that would work. Most of the 9V rechargeable batteries out there are not really 9V... instead they are 7.4V or 8.4V... and would not give enough power to power the wireless mics. Just got a few of these with the matching charger and it works great! Lasts longer than your standard 9V alkaline batteries. We have the lapel mic running for about 2 hours every sunday and the battery meter shows 3 out of 3 bars after the day is over.

I am a professional filmmaker and bought 8 of these batteries and two chargers.
We didnt use them for over a year, but we DID keep them pretty regularly charged, as we should. We are not ignorant as to proper battery "feeding and care", ha! as we have all kinds of batteries and "bricks" etc. imaginable in our studio.
Then, two months ago we started using them sporadically on the set of a major feature film.
BUT...
One by one half of them died to where we we only have four left that will even take a charge.

Best 9V I've Found

By Gabs

Pros

  • Lightweight
  • Long-Lasting
  • Rechargeable
  • Reliable

Cons

    Best Uses

    • Ifb Receivers
    • Wireless Mics

    Comments about iPower 9V Li-Polymer 520mAh Battery:

    We use these 9V in our Lectrosonic IFB receivers for live sports news television. Battery failure is not acceptable in live tv, so we don't screw around with cheaper batteries. I've also used these in the older Lectro mic transmitters that take 9V's and they lasted many hours. They rarely fail on me, as well. I've used other higher-performance batteries and get a 10% failyre rate sometimes. I don't care if most of the batch lasts 8 hours, but 1 out of 10 is going to fail after 10 minutes. These iPower batteries are our choice for rock solid reliability.

              I've cycled them 8 or so times now, they are providing at least 7 hrs of power to my wireless hand-held mics (ULX2). Haven't had occasion to push them farther than that. One of these days we'll give them a bench test.

                Comments about iPower 9V Li-Polymer 520mAh Battery:

                I have been using 16 of these batteries for over 2 years and they work awesome. They are great for wireless mics because they can last up to 5 hrs when recording continually. I never had any problems with them and I would recommend them to every that is looking for a reusable 9v. Simply blow the Ni-MH batteries out of the water.

They charges get zapped to about half and only last under 3 hrs. At least this was my last experience with them. Be sure to have disposable 9Vs on had just in case.

                          We have a lot of ansmann rechargeables and like the AA but the ansmann 9 volts are worthless. These lithiums are great. Be sweet if they made a lithium AA. We use AA's for our UHF-R mics and the ipower 9 volts for our PSM 200 body packs.

                            I use this battery for my wireless microphone when I film weddings. It lasts me for the whole ceremony plus interviews at the reception. It lasts a long time and I can depend on it.

                              I bought 4 of these batteries as a test run in our Shure wireless mics. As other reviews say, they only show 2 out of 3 bars on a full charge, but they last 7 or 8 hours and have a fast recharge time. I'm on this website today to buy more.

                                  Purchased in Dec. 2009, I've used these batteries in two theatrical shows now in Shure wireless systems (LX and ULX) in about 20 mics. THey work flawlessly. When I first got them, I set up a mic and let it run next to our boom box while working on the set. After an 8 hour work day, the mic was still going. For two show days, we do recharge between shows (15 minute recharge time). The newer Shure mics do read even newly charged batteries as "1 or 2 bars" of power, but they hold the whole show easily (we turn them on for mic check, then leave them on until the end of the show, so that's up to 4 hours for our musicals.) I've already recovered the costs I would have incurred for batteries for two shows.

                                    I'm the sound man at our church and we just recently upgraded the wireless mic system to the Shure ULX-P system. I've been looking for a rechargeable 9V battery that would work. Most of the 9V rechargeable batteries out there are not really 9V... instead they are 7.4V or 8.4V... and would not give enough power to power the wireless mics. Just got a few of these with the matching charger and it works great! Lasts longer than your standard 9V alkaline batteries. We have the lapel mic running for about 2 hours every sunday and the battery meter shows 3 out of 3 bars after the day is over.
