Customer Reviews of Energizer NH22BP ACCU 9-Volt Rechargeable Battery
Customer Review: No good for my needs
Summary: 1 Stars
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.
