Panasonic eneloop BK-3MCCA4BA AA 2100 Cycle Ni-MH Rechargeable Batteries (4-Pack) - Pre-Charged for Immediate Use | Perfect for Cameras, Flashlights, Toys & Electronics

Bought these for my drone controller. I used the "other brands" NiMh they sell in stores and they all conk-off after 8 months to year and the runtime is pretty weak. Eneloops are made how NiMh batteries are suppose to be made. These batteries last forever! I'm literally still using my first set over 4 years later. The capacity is much greater and they keep their capacity over the years as well. Stop buying the rechargeables in stores and buy Eneloops. A strong buy!I got turned on to the eneloop batteries many years ago from some folks in a handheld GPS forum, and I honestly haven't bought another type or brand of rechargeable battery since! I'm still recharging and using the original 4 that I purchased probably close to 15 years ago, and they still work great! I've since purchased more and use them in almost everything that drains AA's quickly - xBox and nintendo game controllers, VR headset controllers, flashlights, remote controls, kids toys, etc... They hold their charge for a good long time too, so they're always ready to go. I recommend using with a good "smart" charger like the Tenergy charger (about $40) - avoid the "plug in the wall" quick chargers.They last about 5 years before charge will deplete fast.The battery life definitely starts to shorten but not until quite a bit of use. Great way to save money from buying new batteries. Would highly recommendWe had previously purchased these batteries with the charger and it took MANY YEARS for the batteries to stop charging. This is a great deal as it will save you lots of money on buying batteries every week!I am slowly changing from disposable batteries to these rechargeable ones. I have them in many items and they last a fairly long time before I need to recharge. The charging apparatus is quite easy to use and appreciate the wall plug being foldable for storage.buena calidad y precioThese batteries last a really long time. I am surprised at how long they hold a charge compared to the original batteries that came in my razor.
