Panasonic K-KJ17K3A4BA Advanced Battery Charger Pack with 4 AAA eneloop pro High Capacity Ni-MH Rechargeable Batteries

I use them for Xbox controller and remotes and they last a very long time, the charging does take a little longer than expected and charging the AAA batteries seems a little funky until you get use to it. I would buy these again.

Panasonic has the best electrochemists in the industry; these rechargeables never wear out and hold a charge ~5x a disposable lead-acid AA. I've had them for 6 years now still going strong! They're worth every penny and pay for themselves within a year.

Tried several types of rechargeable batteries but these last longer even with many recharges. Still haven’t had any fail after several years of use.

I just received the product and haven't really used them yet but I wanted to leave this review to clear up something that almost kept me from buying this. The aaa batteries are suppose to be seated on a diagonal, and when this is done the batteries are kept securely in the charger and don't fall out. I was confused at first too because they don't really snap in like you'd expect but they are held in and make proper contact to charge. The batteries came fully charged as well.

I use this battery for my Sony flash and even though I haven’t use them so much the quality of this product looks special

Eveloop has the best recharge batteries. other brand of rechargeable seem to get a "memory" and not have a good voltage after a few recharges. i never seem to have a problem with eveloop. they are made in japan with a great QA process. They say that they have a 1,500-cycle recharging but I'm way behind that, the ones i got back in 2010 (second gen) are still going strong.

Perfect, thanks!

I have two sets of eneloop AA batteries and two BQ-CC17 chargers that I use with my underwater strobes. They have worked flawlessly for several years, and often sit for extended times between dive trips.Based on that, I bought another BQ-CC17 charger with 4 AAA eneloop pro batteries as a set in May, 2024. All four simultaneously went “bad” about a month ago, December, 2024. Lasted 8 months!?! I tried my other chargers, no luck. And the new charger works fine with the older eneloop AA batteries.Tried everything on the Panasonic website to see about replacement, can’t do it. Chat just sends you back into the webpage, no email support or phone number. FAQs simply say batteries need replacing. No kidding!Moral here: if you get a good set of batteries, you are golden. If not, you are out of luck.I would not use these in any situation where reliability is critical.
