My Second Review of this Product, because I bought 1 and than 3 more together with the Charger.
So far, I can say they last for nearly 24 Hours, constantly use and thats what you want from a Batterie, right? It Charges in about 2 Hours, Buy at least 4 and the Charger from iPower and your on the save site on every Set.
The Charger includes a 12V Car adapter.

So far, I did a 24 Hour test with a Preamp, and Headphone Amp and as far as I can say, this Batterie last nearly 24 Hour consecutive use and Charges in no time. But you need to buy the right charger.
The best thing would be to buy minimum 4 Batteries and the Charger.
With Plug Adapter, the charger also worked in Europa. 110-260V

Works as described.

I bought 4 of these along with the 4-bay rapid charging unit. I operate a mobile DJ business and am in constant need of fresh 9 volt batteries. Instead of spending hundreds of dollars on one-time use 9 volts, I opted for this system. They charge in less than one hour and they last throughout the entire gig. No more changing batteries mid sentence! Definitely worth the money in savings. I've tried consumer rechargeable 9 volts in the past, but they didn't quite have enough power to operate my mic.

So far, these batteries last WAY longer than other rechargable batteries. Good stuff!

The ipower 9v Li-Po battery has allowed me to rely less on other Alkili of NiCad 9v products. The ipower 9v runs as long, and longer in some cases as the other 9v products, the ipower 9v weighs less than other 9v products, and is safe to dispose of when its rechargable life ends. I am a ENG/EFP soundman and use the ipower 9v with all of my Lectrosonics gear. In the past 3 years I have owned about 25 of these batteries, and have 13 in service right now. I love this product, wish it was around 20 years ago.

I use these in Lectresonic LM transmitters to replace standard 9V batteries. The application is in a church - so monitoring batteries is problematic and I found we were replacing the alkaline 9v's more often that really probably needed. Most 9V rechargables do not perform well in these devices - less time than an alkaline, but so far these have worked well. They also have a smart charger, so the batteries can sit for days in the charger without damage (previous NiMH batteries overcharged).

I use these batteries in my wireless mics and they last long and preform great.

I have tried a lot of 9v rechargeable batteries for use in musical instruments and other gear, and these are by far the best.

The only disadvantage is the need to get another charger.

I shoot weddings and audio is extremely important to me. I use my wireless LAV kit modified to transmit audio directly from the DJ's mixing board XLR to my camera's XLR instead of using a mic in front of the JD's speakers. I bought the necessary cables, adapters and pads from B&H as well.

This setup sounds like a CD to CD with no outside ambient noise, just the pure music signal because it is between camera and mixer! Anyway, back to the batteries, The regular rechargeable (non lithium) couldn't handle as XLR seems to drag a LOT of power from my transmitter.

GO AHEAD AND BUY! I bought 4 + the proper charger for it. DO NOT ATTEMPT TO CHARGE THESE BATTERIES WITH A REGULAR 9v battery CHARGER!!

Read the instructions not to damage these expensive batts. The charger for these lithium 9V batteries has a switch (lithium and nickel batteries)

I am very pleased and these batteries last me a whole night doing my unusual, high power draw XLR thing...

I am in the video bussiness and my wireless mics use 9volt batterys. I was going thru 4 or 6 nine volts every week. I have been using the ly-polymer batterys and I have been doing 2 shoots on a charge. They aren't showing any weakness after 2 shoots but I can't afford to have a wireless quit during a shoot. I bought 6 baterys and a 4 place charger. I have been rotating them so they all get use. I love them

I bought 10 of these to use in my Audio-Technica wireless body pack, plug-on transmitter, receiver and DVPromix 4 mixer. So far my initial tests seem to show that they work just as well as alkaline batteries.

The only drawback that I can see is that they can be damaged if you run them below 6.4v. What I've decided to do is reduce what I know my typical runtime is by 15-20% and then swap them out. I did test them and run them up to the manufacturer's listed runtime on my equipment with alkaline batteries and when I checked the voltage I was still well in the 7.2v range.
