    Careful...

    I use Energizer almost exclusively because they make great batteries. This purchase, however, was a bit different than expected. I bought this battery for a in-ear monitor system, and the dimensions of the battery seem to be a bit small? I've tried the battery in multiple units and the power to the unit is interrupted multiple times - due to the battery not making a proper connection. Not sure if this is the case for all of the batteries, but I'd just be careful about using this battery for something extremely important. If you have to attach the battery to the device, I'm sure it would be ok, but the IEM units don't have the piece that snaps onto the battery. It's installed much like a AA/AAA battery.

    Not 9V

    These rechargeable batteries are 8.4V -- not 9V as advertised. Some devices may not care about the 8.4V but others will not work because they think the battery is failing/discharged. The 1st generation rechargeable 9V batteries were actually 8.4V (as this one is) but the latest generation are the full 9V. This can make a difference for many electronic devices. Returned.

    I bought this as a gift to a boy I never met. I had also bought him the charger and a RC car. Why because his mother could not afford Christmas gifts so I figured she could afford to by replacement batteries and I remembered receiving a gift of a race car set but it only ran on batteries. When they were dead the fun was over.

    Rechargeable Batteries -- the Only Way to Go

    You never know when conventional batteries go dead, or about to go dead. If they are old, they might be dead right out of the package. Any if you have a battery backup for say a clock, you never know if it will work when it needs to work. Rechargeable batteries solve all of these problems.

    I have a favorite flashlight that, when not in use, still is constantly on at a very low level of brightness to act as a night light. Regular batteries would be drained even if the light was not in use. Having a rechargeable 9 volt solves the problem.

    First time I tried the 9 volt battery. I needed one for my clock as a backup and It seems to work great right now. That's what will be cool, next power outage I'll see if I have to reset the thing again, it's annoying to reset all the time, I never new the old battery had died until then.

    These batteries charged nicely and hold for a long time. I'm glad I bought these for my smoke detectors instead of replacing batteries twice a year I just recharge over a day and keep my peace of mind

    I’ve been using rechargeable batteries in my smoke alarms for a long time from Energizer. It finally became time for new rechargeables and I stuck with Energizer. Can’t go wrong with the bunny lol. They just keep going...

    Best Buy is one of the few places that still carry the 9V rechargeables, and with the free shipping this makes this a great place to buy. I've gotten tons of usage out of my rechargeables (game controllers, stairway lights, etc)

    I bought this battery for a smoke detector. After I opened the package I recharged the battery before I installed the battery into smoke detector. My smoke detector starts beeping from low battery every two weeks. I would not recommend battery.

    I needed a backup battery for my wireless microphone. I ended up getting 2 of these and I'm glad I did... It does the job and makes me worry a lot less about my power solutions for my devices...

    These batteries I live by. I use the 9v for my metal detector and they've never left me hanging. They last multiple days before I need to recharge them, and overall the batteries can last for years with proper care.

    Bought two of these batteries for a wireless microphone, battery lasts at least 8 hours before microphone lights up for low battery. They are great for musical events. Charge them the night before and they will last at least 8 hours on a Shure Mic.

    Most people think a battery is just a battery. Not so. People think the 'Energizer bunny' can keep on going. Also not so. However this battery is different, IO can recharge this one for continued use.

    I have a 15 year old tens unit and the batteries no longer kept a charge. These new rechargeable batteries last much longer than the original batteries when they were new. I had trouble finding them till I looked at Best Buy.

    It does a great job. Having a rechargeable battery around is great. I just hate now that it's harder to find them when I need them, making it much more impossible to use.

    I love Energizer Rechargeable Batteries. Buy them once, and then always have them on hand for your smoke detectors, etc. They are a great value. And, Best Buy is one of the few places that keeps them in stock.
