    Charge doesn’t last long

    I bought the battery for dedicated use in an electric guitar. After charging the battery overnight I plugged it in to the guitar and played for just under an hour. A few days later I picked up the guitar again and the battery was dead. It’s like it’s draining when plugged in but not in use. The battery works fine when charged but I would need at least 2-3 batteries if I played every day. If I was a professional musician this battery would not been in the kit.

    Having the rechargeable volt battery is awesome! I hate going out to have to buy these for my bed and my kids toys, so this was an absolute must-have.

    This is a good battery but the only reason I bought it was because the store was out of lithium ion's. Lithium are much better batteries.

    It’s too expensive for the charger and my battery didn’t work. I might be drained.

    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...

    dependable battery

    Charge it and it will last forever it seems like. I recommend running it all the way down before charging it back up as batteries only have a certain number of cycles. Good price too. Better than other places i shopped.

    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.

    Not 9V

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    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.
