Panasonic K-KJ17KHCA4A Advanced Individual Cell Battery Charger Pack with 4 AA eneloop pro High Capacity Ni-MH Rechargeable Batteries

Works great on flash, long life, good quality

Need batteries that work well for a camera flash, look no further. These rechargeable batteries have the power needed for using high power flash photography. While other batteries I've used run out of power, these Eneloop pro last. No argument in the value of rechargeable batteries. The alternative is to waste money. The charge base is not bulky which is a plus traveling with my gear.

Enloop was recommended to me by a friend due to their longevity so I gave these a chance when they were on sale.We've been using this charger and Enloop batteries around the house for about six months now for items like remote controls, video games controllers, flash lights, etc. No complaints so far.You should know, the charger is on the slower side. This is a feature in that a slower charge makes for batteries that will retain more of their energy capacity over time. I haven't paid attention the the actual time, though, honestly. I just placed the dead batteries in the charger. I remove them whenever I get around to it and add them back to the charged battery container.The batteries power everything as they should. There has been no noticable loss of capacity so far. I expect these will last a long time. The best feature is that we no longer go through large numbers of alkaline batteries.

As a photographer, battery use and longevity of charge are very important. Previously I have used rechargeable AA batteries and had to recharge them after every photo shoot. I learned about the Panasonic Eneloop pro AA batteries and decided to give them a try. After one photo shoot during which I frequently used the flash unit, the eneloop batteries were still fresh. I was impressed and bought two charging units with 4 AA batteries. To date, I have not used the battery chargers as the batteries are still nearly fully charged. One thing I liked about the chargers is that they can charge both AA and AAA eneloop batteries. I think the eneloop system is worth the price and an excellent value. I am glad I learned about eneloop batteries.RK

Probably the best reusable batteries

It hasn't been a year of once week use, and the wear is far worse than I expected (see attached photos).These batteries are only used once a week for the church microphones. The physical appearance wouldn't bother me much if it didn't affect the batteries but it does. It seems the decorative outer skin is also an insulation, because these batteries in the picture attached to not work sometimes. It seems they short out or something when in the mics. We no longer use these.Other than that... The batteries deliver strong, long lasting power that last for entire day, and sometimes for two days when I forget to charge them. Power delivery is on point and saves us a lot of money buying batteries every month. Wish they address this in the future.

If you're tired of buying expensive one-use Energizer Ultimate Lithium Ion batteries for your Blink Cameras, but don't want to use rechargeable Li-Ion batteries quite yet, these Eneloop Pros are a good compromise.Here's the capacity facts.Energizer Ultimate Lithiums - 3500 mahEneloop Pro NIMH - 2600 mahThe one-use Energizers have 30 percent more capacity so these Eneloop Pros will not last as long.However, in my experience, Eneloop Pros last between 1-1.5 months after a full charge in my front door Blink Camera that gets heavy usage.Between Nov 1, 2024- Feb 10, 2025, I've only had to swap out and recharge my blink camera batteries twice. I think the last set was closing in on 2 months before the cameras became unresponsive and needed a fresh charge.The app WILL show a low battery always as the nominal voltage of NIMH is at 1.2 volts. Just ignore that.I'm quite satisfied with the performance of these Eneloop Pros thus far. If you don't mind changing your blink camera batteries a little more often but like the convenience of recharging and not having to shell out extra for one-use Energizers, these are A-OK.
