Eneloop Panasonic BK-4HCCA16FA pro AAA High Capacity Ni-MH Pre-Charged Rechargeable Batteries, 16-Battery Pack

Great product. Holds a charge for a long time. A lot less expensive than buying throw away batteries. I used them for all my electronic products: remotes, clocks, headphones…

I’ve been using the AA Eneloops in a cellular trail camera all winter long, outdoors, with average temperatures around 20°F and frequent drops to 0°F. The camera app shows battery status, and after more than 6 months of use, they’re still holding close to 50% charge — on a single charge!No other AA battery even comes close. I used to replace disposables every 6 weeks in this same setup, so these last at least several times longer than even the high-end throwaway brands. And again, I haven’t recharged them once yet.They’ve already paid for themselves in the money I’ve saved not buying disposables — and the best part is, I can keep recharging them many times over.I've also had trouble with disposables in the cold — below 25°F they’d often just die completely until it warmed up again. But these Eneloops don’t seem to care about the cold at all. They’ve handled 0°F with no issue.I’ve already bought more and plan to keep buying them. I can’t recommend them enough. If you’re on the fence — don’t think twice. These batteries are the real deal.

PROS/What I Like:1. VERY long lasting. I have over 5 years of use and going strong! Company claims 10 year life span up to 70% charge2. Maintains great charge3. Environmentally friendly by reducing toxic waste vs disposable single use batteries4. Convenient. Don't need to go to the store to buy batteries all the time. Just switch them out with your extra batteries and charge them up!5. Out of box factory SOLAR POWERED pre-charged for instant use6. Maintains up to 85% of charge after 1 year when not in use7. Pro version is higher capacity and power @ 950mAH vs standard version @ 750mAH8. High capacity up to 500 charges!9. Extreme temperature rated down to -4 deg F.10. Made in Japan who continues to design and manufacture high quality productsCONS and Other Considerations1. Not really a con but more of a consideration, the charge time is 4 hours for the black pro battery and 2 hours for the white or green standard version. This hasn't been an issue for me because I always keep extra charged batteries available.I got tired of buying bulk batteries from Amazon or Costco only to have them die and then run to the store when one of my devices needed a fresh set of batteries. Not only that but I felt bad throwing them away because I knew you are supposed to dispose of them properly since they are considered toxic waste.So about five years ago I bought the green and white batteries you see in the picture. We have used them for everything from flashlights, remote controls, cameras, wireless keyboards, wireless mouse, LED candles, Xbox and PlayStation remote controls, electronic bathroom scales, and basically everything that needs a battery. I am still using the original batteries from over five years ago but decided to purchase more due to the needs of batteries in my kids remote controls and our household items.I upgraded my Eneloop to the Pro version and still love them! They hold a longer charge and provide more power so I can use them for a very long time before needing to replace them. This is great for the environment and also more efficient to not always have to go out and buy batteries if I need one. I just charge them up and they are ready to go for a long time. I HIGHLY recommend these to anyone needing a longer term battery solution.

Great batteries! Hold charge very well.

They last long. My remote has a very bad parasitic battery drain issue that I'm too lazy to investigate, so these do the job. Some times they're finicky as far as charging, but they work I'd say 95% of the time.

It will take a while but I expect these will more than pay for themselves vs alkaline cells.One thing to keep in mind, the convenience expected may be shortlived if the device these are intended for expects the full 1.5v from a typical cell. Some things like camera's can be fussy and complain and you will be changing batteries more often than expected. If these cells are overly discharged the charger will need a maintenance feature to overcome the low volts and to prolong the cell lifetime. El cheapo chargers are not a good match for such cells.

Love them! I bought a previous version of eneloop rechargeable batteries sold at Costco years and years ago and they still work. I'm glad to own an upgraded version.

Great quality batteries that result in savings in the long term as they have a low self-discharge so are always ready to be used and have a good capacity so can be used in higher drain applications such as torches but also work well in remote controls or radio controls for radio controlled toys.
