Review: The "just right" smart charger from Panasonic. The other models are too fast or too slow. - This is an excellent NiMH battery charger. You can use it with any brand of NiMH battery, and because it's a smart charger it will always charge the battery perfectly. There is a green light under each battery while charging, and the light turns off when charging is complete. The light will blink for a few seconds when the charge is checking the status of the battery, and the blinking will continue if there is a problem. "Smart" chargers constantly measure the condition of the battery to determine if it's time to stop charging. There are "dumb" chargers out there that operate based on time, so they always over-charge the battery, resulting in the battery converting the excess charge to heat and damaging itself. Avoid dumb chargers. With NiMH batteries, chargers that are too fast or too slow will undercharge or overcharge the battery, while normal-speed chargers will charge the battery perfectly. This charger is a normal-speed charger. I think the speed of this charger is acceptable, as you can leave it on overnight to charge and they will be ready in the morning. However, if charge speed is important to you, don't feel bad about buying the Panasonic fast charger, because batteries are meant to be used and the batteries will still last a long time even if fast charged. Note that fast charging also makes the batteries hotter, especially towards the end of the charge cycle, and heat can damage batteries slightly (again, nothing to worry about if fast charging is important to you, just know that your batteries will not achieve the 2100 cycles if fast-charged every time). This normal-speed charger only makes the batteries slightly warm, as expected. Because this charger charges at what I consider the ideal charging speed for NiMH, I believe it is the best charger available from Panasonic. As long as you keep a supply of already-charged eneloop batteries, you won't mind waiting for batteries to charge because you can just use your already-charged batteries. White-label eneloop batteries have such low self-discharge that keeping a supply in storage won't be a problem; they will always be ready to use! For the black-label eneloop pro batteries, which have a higher self-discharge, you should probably recharge them every 1 or 2 years if you want them to be ready-to-use from storage. Use rechargeable batteries for ALL your devices! You might find a picky device that doesn't like the 1.2v to 1.4v voltage of an eneloop NiMH battery; in that case, I recommend searching desertcart for the 1.5v rechargeable lithium batteries such as TENAVOLTS or other brands. Those rechargeable lithium batteries provide a constant 1.5v, filling the gap for the few devices that an eneloop battery can't work in. That way, you will have completely switched over to rechargeable batteries! Review: Leak Free, Reliable, Economical, and Environmentally Responsible - I'm an eneloop evangelist these days because they work so well in AA and AAA flashlights, kids toys, remotes, and countless other devices around the home. The initial upfront cost seems a little steep at first, but when you start using them and realize how quickly they pay for themselves, you are going to wish you had more for everything in the home and that's how this all begins. Take a chance on them. You won't regret spending extra for the high quality eneloops. The other brands simply cannot compare. ## Features - LONG LASTING PERFORMANCE: Recharge eneloop AAA rechargeable batteries up to 2100 times - POWERFUL NiMH RECHARGEABLE BATTERIES: eneloop AAA Ni-MH pre-charged rechargeable battery deliver up to 850mAh typical, 800mAh minimum - PRE-CHARGED AND READY TO USE: eneloop AAA rechargeable batteries are pre-charged at the factory using solar power and maintain up to 70% of their charge after 10 years (when not it use) - ADVANCED CHARGING CAPABILITES: The Panasonic CC17 battery charger individually charges each eneloop AA and AAA rechargeable battery, resulting in a perfect charge every time - 4 INDIVIDUAL LED INDICATORS: The CC17 battery charger features 4 separate LED charging lights, one for each unique charging station - BATTERY DETECTION TECHNOLOGY: Each eneloop AA or AAA rechargeable battery is analyzed (when the battery is installed) and the charger station for that battery will end the charging process when each battery has been fully charged - SECURE, PROTECTIVE PACKAGING: This package contains four eneloop AAA rechargeable batteries (made in Japan) and one CC17 charger, packaged together in the U.S.A. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B010U57MSW | | Batteries | 4 AA batteries required. | | Best Sellers Rank | #78,443 in Health & Household ( See Top 100 in Health & Household ) #124 in AAA Batteries #181 in AA Batteries | | Customer Reviews | 4.6 4.6 out of 5 stars (2,245) | | Date First Available | June 29, 2015 | | Is Discontinued By Manufacturer | No | | Item Weight | 5.6 ounces | | Item model number | K-KJ17M3A4BA | | Manufacturer | Sanyo | | Product Dimensions | 4.75 x 1.25 x 8 inches | ## Product Details - **Brand:** Panasonic - **Color:** gray - **Item Weight:** 0.35 Pounds - **Output Voltage:** 1.2 Volts (DC) - **Product Dimensions:** 1.25"D x 2.63"W x 4.3"H ## Images ![Panasonic K-KJ17M3A4BA Advanced Individual Cell Battery Charger Pack with 4 AAA eneloop 2100 Cycle Rechargeable Batteries - Image 1](https://m.media-amazon.com/images/I/71dluL4-RmL.jpg) ## Questions & Answers **Q: Picture shows aaa too short for charger to reach contact points. Does it work?** A: Be sure to read the enclosed instructions for the charger regarding proper insertion of both size batteries. As already noted, different contact points and different insertion techniques. If you are forcing AAA's in place (and ruining the charger contacts) or they fall out you are doing something wrong. **Q: Waterpik toothbrush has battery 3.7V, can I replaced with these battery?** A: No, this is a different type of battery, different voltage. It would not work. **Q: How long it takes to charge 2 aa with an advanced charger?** A: TL;DR: 2.5-3 hours I'm not entirely sure what an "advanced charger" is but my charger outputs 3V@1550mA to two AA batteries. At this rate the batteries should take roughly 2.5 to 3 hours to charge. Your charger is likely not very different so I would expect the same. I'd recommend having enough so that you always have batteries to swap with because that is extremely convenient. **Q: What about use in Europe, will an adapter work? Can it withstand the higher voltage used there? Thanks!** A: The answer by jennicalaura is incorrect. The charger is 100V-240V Auto Voltage. It's printed right on the package (see left side of the picture). So yes, it will work in Europe with the appropriate adapter and without using a transformer. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The "just right" smart charger from Panasonic.
