Product Reviews of Energizer NH22BP ACCU 9-Volt Rechargeable Battery
Product Review: They don't know what their talking about.......
Summary: 4 Stars
I have bought 6 energizer 9V batteries already and they work just fine for whatever application. I mainly use them in our churches wireless microphones and remote controls. Yes it does state nominal voltage of 7.2 volts. I have tested numerous times with a DMM and the reading was at well over 8.4 Volts fully charged. Most people don't understand the technical jargon involved with batteries or electronics. Energizer is recommended as one of the top 3 NiMH batteries on the market. Still curious look at their tech sheets or call someone.Product Review: They work for me..
Summary: 5 Stars
I teach 4 one-hour classes a week, which require a 9-Volt battery for the mic. I got tired of buying these every week or two, so I bought the rechargable. The single charge lasts the entire week. I recharge it on the weekends and I'm ready to go...no problems so far. I've had it for 3 months or so..Product Review: Used for video productions in Las Vegas
Summary: 4 Stars
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.

Product Review: Works good
Summary: 4 Stars
We use this in our alarm clock for when the power goes out as it often does. So far this little rechargable hasn't needed a recharge & is doing a fine job making sure when get up on time when the power goes out & then back on while were sleeping. I gave it 4 stars because we haven't had it long enough to get a really good opinion on it aside from the one just given.Product Review: Works well but needs charged frequently.
Summary: 3 Stars
I have been using rechargeable batteries for years (AA's only) so when we found out we were expecting a new addition to our family, we began purchasing other sized rechargeable batteries for all of the battery operated baby gear we were planning on using. They cost more initially be were were aiming to save more in the long run and reduce the waste created from used disposable batteries.
We only have one rechargeable 9 volt battery that we use in our baby monitor. It's just a basic baby monitor, nothing fancy. Perhaps a rechargeable battery isn't the best battery to use for this particular application because I end up charging these batteries twice a week or so. I don't mind but sometimes it is a pain- when the batteries die and he's just laid down for bed and I'm trying to catch up on housework.
Although I will say, that they do work just as well as regular batteries except that they must be charged frequently. I should also mention that I have never tried using disposable batteries in the monitor, they may drain just as fast?
At any rate, these are good batteries. I've always preferred Energizer over other brands. And I am really not disappointed with this battery either. It's all in perspective.
