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

These were purchased for use with a Streamlight Protac and other multi-fuel flashlights and they work great. I used one of these batteries in a small, single AA 90° Potrac that I use daily, and it lasts a long time. These are not lithium, they're nickle-cadimum with more than double the capacity of a CR123 rechargeable lithium ion. My new favorite rechargeable battery!

I was using a set of four AA batteries every time I took photos. With these rechargeable batteries, I can use them over and over. The battery life is much longer and stronger; these batteries will keep me going for a long time. Peace of mind is everything.

Batteries came pre-charged and ready to use. The charger is compact and easy to store and use, and the charge rate matches what’s advertised. Solid product!

I bought these to power a Uniden BC125AT scanner. They have some more mAh than the batteries that came with the scanner, and a good reputation. Plus, there's a wall charger. These last FAR longer than the stock batteries.

Update: 5/1/2025 - Currently going on 60 days since I last charged my Blink Camera batteries. I think this is how long the Energizer Ultimates lasted. I'm SUPER impressed with how these Pros are performing. Like, HOW?! =) 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 mah Eneloop Pro NIMH - 2600 mah The 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.

First of all, I am happy with this purchase. In particular I bought these batteries for use in camera flashes and they work nicely. They deliver sufficient current to recycle the flash rapidly and enough voltage to keep the electronics functioning. Regarding the charger, it is nicely constructed. It feels sturdy enough and the fold flat connector on the back is handy for storage. The device is simple to use and works nicely for AA and AAA batteries. It detect voltage and charging rate delta on a per battery granularity meaning it will not charge a battery that is already full (voltage high) and will stop charging each battery when the charging rate drops (capacity reached). The down side to all this is the charging current. Despite having the smarts to avoid overcharging it only charges the batteries at 300mA (for AA) or 150mA (for AAA). The result is a 9 or 7 hour charging time respectively. This means they work nicely for charging overnight or for top up charges but a fast charging mode would have been nice. A appreciate that low current charging yields better long term battery life/capacity but there is a comparable unit that will charge 4 batteries in 3 hours or 2 in 1.5; if this had such a fast charging option (a button to enable said mode) then it would be just about perfect. Overall this is a nice charger and looks nice in the wall with the corresponding batteries on board, just a little slow.

I recently purchased the Panasonic K-KJ17KHCA4A 4-Position Charger with AA eneloop PRO Rechargeable Batteries and I am extremely happy with my purchase. The charger is very easy to use, and it can charge up to 4 batteries at once, making it very convenient for me. The eneloop PRO Rechargeable Batteries are of high-quality and provide excellent performance. They have a longer lifespan compared to traditional batteries, which saves me money in the long run. The batteries are also very reliable and consistent, providing a consistent level of power output. The charger also comes with a variety of safety features, including overcharge protection and temperature control, which ensure the longevity and safety of the batteries. Overall, I would highly recommend the Panasonic K-KJ17KHCA4A 4-Position Charger with AA eneloop PRO Rechargeable Batteries to anyone in need of reliable and long-lasting batteries. This product is a great investment and provides excellent value for money.

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

Excelente ... segura muito mais carga que as outras, mesmo quando não está em uso

Excellent so far - holds charge extremely well.

Excelente calidad de pila con gran duración.

Je suis absolument ravi de mon achat du lot Panasonic KKJ17KHCA4A Eneloop Pro, qui comprend le chargeur de batterie individuel et quatre piles AA Ni-MH rechargeables. Ce kit est tout simplement exceptionnel pour quiconque utilise régulièrement des appareils électroniques. Le chargeur individuel est une fonctionnalité que j'apprécie énormément. Pouvoir charger chaque pile indépendamment assure une charge optimale et prolonge la durée de vie des batteries. Le fait qu'il y ait quatre emplacements individuels est parfait pour mes besoins, et les indicateurs LED clairs vous renseignent sur l'état de chaque pile. Il est également compact et facile à transporter, ce qui est un plus. Quant aux piles Eneloop Pro AA, elles sont à la hauteur de leur réputation. Leur capacité élevée (2500 mAh) est remarquable, et je constate une autonomie significativement plus longue pour mes appareils gourmands en énergie, comme mon flash photo, mes manettes de jeu et mes jouets pour enfants. Ce qui est le plus impressionnant, c'est leur faible autodécharge ; elles conservent leur charge pendant des mois, même lorsqu'elles ne sont pas utilisées. En bref, ce lot Panasonic Eneloop Pro est un investissement intelligent. Il offre la commodité d'un chargeur de haute qualité et la performance supérieure des piles Eneloop Pro. C'est un produit fiable, efficace et durable que je recommande sans hésitation à quiconque cherche à dire adieu aux piles jetables.

I've been using Eneloop batteries exclusively in my Xbox controllers for several years now and can confidently say these are the best batteries I've ever used! Not only do they last longer than the "name brand" Alkaline batteries I was previously using, they're rechargeable which results in less environmental waste and more money in my pocket. Win/Win! I use these batteries primarily for my Xbox Series X controllers. I game several hours daily, as well as using to control/navigate apps, streaming, bluray player etc.. and these batteries last a week+ before needing to be recharged. The charger(BQ-CC17) plugs directly into an outlet and is fairly low-profile. A green LED light is visible for each battery during the charging process. The LED lights turns off and the charger will shut-down once charging is complete. This is a great safety feature, especially for overnight charging. Charging takes approx. 7 - 8 hours to complete. Since this package includes 4 AA batteries, its perfect for me as I can easily swap for 2 fresh batteries while 2 are being charged and ready for the next swap/rotation. Previously spending $10 per month on non-rechargeables, these Eneloops have already paid for themselves. I've been using them exclusively for over a year with no issues. If you're looking for long lasting, quality rechargeable batteries... I recommend you try Eneloops. ★★★★★ The environment and your wallet will thank you!
