 Great Battery May 8, 2008
I bought two of these batteries with the Overnight Nimh Family Battery Charger, and so far the batteries have performed as expected. haven't used it enough to see if they take memory if charged to frequently but so far so good. Great product!
Works well but needs charged frequently. April 29, 2008
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.
 Works good January 26, 2008
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.
 No good for my needs June 17, 2007

I'm a strong supporter of rechargeable batteries, but at 7.2 Volts, this just doesn't meet my needs. Devices that use batteries are designed to work across a range of voltages because as the battery is used, the voltage slowly drops until the battery just runs out of juice. When the dying battery crosses a certain voltage threshold, some devices warn you of a low battery. This is a good thing, because you don't want, say, your smoke alarm to need to go onto backup battery power and not have the juice it needs. The problem here is that the devices I use seem to cross the low battery voltage threshold somewhere around 7.0 volts. That is to say, I put a fully charged battery in there and before I know it (about 1 week or 2), the low battery light comes on in my answering machine or the smoke alarm starts doing it's low battery beeping thing. Nope, this is no good. I suggest you steer clear of Energizer and go for another brand that has an 8.4 nominal voltage (or better yet 9.6 if that extra .6V isn't going to harm your device--NiMH cells go in increments of 1.2 V so as far as I know there is no way to get a 9.0 V battery).
Sure this will work in many devices, but I really don't see why Energizer opted to go for a 7.2V battery instead of 8.4V other than to save a small amount of money. That seems like a very off-brand sort of thing to do. 1 star only from me.
Get a real 9 volt battery March 10, 2007

This battery, like other rechargable batteries I own, is rated for 8.4 volts and I'm told is likely even less. Why not go with Maha? It's rated at over 9 volts, which for my applications (powering a headroom micro dac) makes all the difference. I can only imagine that a battery with a rating which conforms to a devices' designated power requirements, is better across the board.
