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.

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.

This review is from: 4 pieces of 9V 250mAh NiMH high capacity rechargeable Battery (Electronics)

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.
