 A set of 9V workhorses! Mar 02, 2009
By Breezy Bring
The performance of these batteries has been surprisingly good! I've been using them for almost one year now. I use them in a set of Shure wireless mics (see my review of the mics on Amazon.com). They have been doing an outstanding and demanding job. Their capacity is very good. Additionally, I feel environmentally green by using rechargeable battery. They pay for themselves after few recharges easy. I've been very happy with this product. Highly recommended.

Good Choice Mar 10, 2009
By A. Perry
They came charged and the spec's look good. I have used them now only a few weeks, but they are holding a charge as well as I'd expect. I'll report later if they disappoint me. For now though, I'd recommend. I use them for my DVM and other electronic devices.

reliable and long lasting so far May 23, 2009
By buru buru piggu
I bought two of these Tenergy 9V's for the smoke and carbon monoxide detectors in my kitchen (they came as part of a set: V3969A1 Plug-in Type Speedy NiMH & NiCd Charger with 14 cells (8AA /4AAA/2 9V) --New!!). I got fed up with the frequent replacement of alkaline 9V batteries. They'd last a month or two, then the alarm would start chirping annoyingly to indicate the need for replacement. Then I'd have to stand on a chair and tiptoe precariously to reach the ceiling mounted alarm and fumble with the cover.
Not being a well-known brand, I was unsure whether I would be able to rely on Tenergy. But after 8 months of using these and the other sizes, I am pleased with their performance and bought 12 more 9V's for the other detectors in the house and a TENS muscle relaxer. It has been at least 4 months since I inserted the Tenergy batteries into the detectors and they haven't needed recharging yet, so I am quite pleased with their life and energy capacity.
Their price to performance ratio is hard to beat. A regular alkaline Energizer at the local CVS is $5. They can only be used once. These can be recharged hundreds of times, making them very cost effective. (Tenergy claims up to 1000 charges, but real world performance will be a lot less).
Highly recommended.

 Premature Deaths Sep 26, 2010
By Mr. Douglas A. Bem

We bought 10 of these for wireless in-ear monitors at our church, intending for about a 3 hour use per day. They did not last more than 15 recharges before either failing to last that long or dying altogether. In four months time 5 of the 10 no longer hold charges at all. Very disappointed that we have to replace these so soon.

Great buy!!! Sep 14, 2010

Re: 9V 250mAh NiMH high capacity rechargeable Battery
Buy them for your hi-drain devices... NOW!!!
I'm a musician (mainly keyboards but) I DO utilize 2 wireless giutars setups that need 9v batteries. I play about 10 times a month (4+ hours a night), so the Return On Investment was almost instantanious. Bought the 10 or 12-pack with the NiMH charger and can't be happier after a year and a half.
PLEASE NOTE: If you have flashlights or smoke detectors, NiMH batteries (simply by their design) are not intended for use where your device is rarely called upon (emergency/backup flashlight) or if your device requires a low but constant power source that's "on" for months at a time (smoke detectors). NiMH are not meant to hold a "long term" charge (and may have up to 40% loss of charge after 1 month). They're plimarily for hi-drain devices (Digital cameras, Wireless mic and guitar transmitters or constant duty flashlight and scanners) that need to be used for hours at a time until they need a recharge.
PLEASE ALSO NOTE: While researching NiMH batteries I found out you should get a 9V with a higher (250mAh) rating like Tenergy. Radio Shack 9v NiMH batteries are only rated at 125 mAh. They're both good batteries, but the higher mAh means the longer it will hold the charge. As a FINAL TIP, don't leave ANY batteries in your pockets unless they are the only thing in that pocket. I lost 3 because they shorted out against something else in my pocket, and since 9v have the + & - contacts next to each other... the more likely this is to happen. Mine didn't explode but they swelled up and got pretty warm in my pocket. Of all people, I sometimes forget this simple fact. Hope these tips help you in making your selection. Get the charger too, unless you already have a "NiMH" charger.
TENERGEY IS THE WAY TO GO!!!
