Duracell Rechargeable Battery Charger Flashing Red

Great battery that last for years. A few years ago (2008 to be more exact) I decided to try rechargeable batteries again, now that batteries started to switch to longer lasting battery technology. I started with energizer and it failed badly so I waited about 2 more years before I tried Duracell. I had gotten a wireless headset and was going through about 2 AA batteries a day. I tried Duracell rechargeable batteries and it worked like it was supposed to. I now use Duracell in all of my battery powered devices and have no complaints.

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.

My APC UPS sounded off every few hours with beeps and a flashing red light to let me know it was time to replace the battery. I ordered online and the battery arrived sooner than expected. I installed it and it's been working fine since. The part I especially like, I didn't have to shut everything off to install.

As many others mentioned in the reviews, these batteries are now new old stock, as the newest ones were made in 2022 and will arrive completely discharged. DO NOT give up on them - the charger will initially show an error (chamber and calibration light flashing) - keep taking the battery off and putting it back on, and eventually it will start to charge. The key is to not leave it in the charger if the charger is showing the error code, you have to remove and replace the battery until the charger shows that it is charging (chamber light and 50% light flashing). After a few hours the 50% light should glow solid and 80% should start flashing, and eventually it will charge fully

Bright white light is very bright. Red/red-flashing light is cool -- not sure if I'll ever use it. Good fit and balance (with batteries in back). Lightweight and comfortable. Looks suitably geeky. Very happy with my purchase.

During the holiday season we would place our battery powered candle in our bedroom window... So on December 5th 2016 my husband unexpectedly passed away. That evening I made a decision I would keep our electric candle lit and it’s been lit ever since and I owe it all to my rechargeable Duracell’s! So today, my candle is the first thing I see when I awake in the morning... And it’s still lit! Thank You Duracell! Your reliable rechargeable batteries have kept my candle lit and has really helped me in my grieving process.

Good rechargeable batteries and charger.

Ever since Duracell first came into the market it has always been my brand of choice. Duracell Rechargeable do not disappoint they are great and live up to the high quality that is expected.

I have owned Eveready, and Duracell rechargeable batteries. Many of them have, after only a few years, failed to hold a charge. That has never happened with Eneloops. I use their charger as well.

From my experience with rechargeable Energizer, Duracell, Pearstone/Watson this batteri wins. At this time I use them in any remote control, watches, flashlights and flash wireless. Having Eeloop is mach smarter option then regular batteries or any other brands.
