The title says it all.. Dont waste your money... Im going to put this out with the rest of the trash...

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!

So now I have used this product for 5 months on a Microphone to line amplifyer and they last about 2 days on average. The batteries take 10 to 13 hours for a full charge which is pretty ridiculous! luckly I only use one at a time so I have time to charge the other one.

I would still say Great Product!

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.

The energizer rechargeable 9 volt batteries are not worth anything - they are better than most of the other ones out there, but that's not saying much. All other batteries are o.k.(AA, AAA, C, D) - it's just the 9 volts that need to go back to engineering.
