 Know what you want firstApr 23, 2003
By ak2005
I read the reviews by other people here and am wondering loudly whether they know what these batteries are for? they are Rechargeable batteries for high-drain devices that require higher mAh rating. NiMH batteries or NiCd batteries do not hold charge like an alkaline battery so if you have charged an NiMH battery and put it in say an alarm clock, the batteries will lose charge in less than a month. they are for immediate usages like digital cameras where you need high mAh batteries and that digital cameras drain batteries. its more like "spend it immediately" battery unlike the disposable batteries that discharge in a circuit but drain very slowly when not in a circuit. I use Energizer AA batteries for my digicam and they recharge the flash much faster than even the best disposable batteries. A best guide is to look whether the appliance for which you are buying this battery is listed on the package or is identical to those on the package. this 9V would be a great thing for a toy where the battery drains out fast and you cannot afford disposable ones everyday.
Just a note: If the device is a direct draining one like a motor and not in a solid-state circuit, do not use a rechargeable battery since if they are completely drained, they cannot be recharged.

 Low VoltageDec 27, 2001
On the packaging and on the front of the battery, it is listed as a 9V battery. However, this is a nominal voltage based upon its format and size. On the back of the battery, it fesses up that this is really just a 7.2 volt battery. In other words, they just used 6 - 1.2 volt cells. I have seen other "9V" NiMH batteries that use 7 cells for 8.4 volts. This battery is only good for devices that require significantly less than 9 volts to operate.

 Excellent if you buy them for the right purposeDec 18, 2003

I use several of these for my paintball gear. It is something that is a use it or loose it type thing. They aren't designed to be used over a long term. Charge them, use them, and then recharge them before next use. They are designed to be that way. Not for a smoke detector, that is for sure. They have a higher flow rate, meaning when I put it in my paintball hopper, I know that I am good to go for the day. When I am done for the day, I just take it out and wait till the night before its next use, then charge it back up. With no fear of it failing on me the day of use. I highly suggest it for uses such as mine, or digi cams and the like. Something that requires a lot of power for a short term.

Certainly not worth $10 eachJun 05, 2009
By M. Gary
We use 9v rechargable batteries at our church. These will only last 2 hours in a wireless microphone. They will barely last 2 hours in our wireless audio packs (ear buds) and when I use them for my electric bass wireless transmitter device they barely get through 30 minutes of use per charge. Since we have three services and practice that morning as well, these batteries do not cut it.
We found these Digimate 280mAh rechargeable 9v's that work much better... we can get two complete weekends from one charge on these... plus, they were only $5 each.

Used for video productions in Las VegasSep 14, 2006
By Andrew R. Hamilton
"Videographers in Las Vegas"
Our Las Vegas videographers use the Energizer 9 volt rechargeables in our wireless mics for many of our events. They are great for high power over short periods of time. I'm sure they would be horrible in baby monitors, smoke detectors, etc. but that is not what they are really made for. Good solid battery but costs a bit more than its competitor "Rayovac" 9 volt rechargeables.
