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

These are great Batteries. I use them in video game controllers, remote, control, controls, and everything else I have that uses batteries & these hold up great!

Good quality; worth the price.

You have to make a routine when it comes to rechargable batteries. They are most alive when used commonly. These have been lifesavers, and have helped keep our costs down. I keep enough at home to fit all the devices, and 4 extra always charged waiting. Then when a device dies, i take out the batteries, put in the extra ones, and charge the old ones. So what works in our house, is to use these for the items that are used the most. Mainly our motion alarms, our remote controls, and our commonly used wireless devices.

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.

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.

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.

GREAT BATTERY RECHARGEABLE ITEM/PRODUCT! no more buying AAA duracel anymore

I did a lot of research into rechargeable batteries and chargers before I bought this because I had no experience using rechargeable batteries. What I like about the charger is that you can charge any combination of AA or AAA batteries and it stops charging when they are full. The indicator light is very helpful in letting you know when they are charged. The batteries seem to last way longer that even the best throw away batteries I've used. Batteries used to last me less than a week in my fire stick remote. (My daughter loves to scroll and push buttons when choosing a youtube show). Now my batteries last almost a month and I don't have to keep a watchful eye on them while they are charging so I can put them in overnight.

There are without a doubt the most reliable, not the "best" but certainly the most reliable AA or AAA batteries money can buy, fight me. That being said, this charger is the stupidest thing I've ever seen. It has GREEN lights to show when batteries are charging and the lights go out when they are fully charged. Every other battery charger made in the history of mankind, including every other Panasonic charger, has RED lights to show when batteries are charging, and GREEN lights to show the batteries are fully charged. This charger is borderline unusable in a profesional environment, film, TV, theatre, fire, police, medical, etc, because of this issue. Someone could mistakenly grab a set of half charged batteries thinking they are full and ready to use. I don't understand how a product with the suffix "Pro" could have this big of an oversight. However, for the home-gamers out there it's no big deal, buy it, you'll love it!

Son increíbles, para mi mouse duran meses con una sola carga. Al cargar es muy rápida a comparación de las baterías normales.

Preciso funciona perfeitamente

estoy muy satisfecha, aunque están caras valen la pena porque no son como otras que las cargas y si no las usas se descargan. Aparte duran bastante.

Não é compatível com as tomadas usados no Brasil, se você comprar vai precisar de adaptador para usar nas tomadas, não recomendo a compra por causa disso, se achar uma versão compatível com o padrão brasileiro, compre sem medo.
