The best thing for the money, Im glad I chose this option.

It was bought exclusively for AA and AAA batteries, the cooling system was finalized. Having printed out the upgraded back cover for the 80 mm fan, I set the silent Artik to 1600 rpm. It's completely inaudible.

Pros
  • One of the best chargers for Ni-cd and Ni-Mh batteries in this price segment.
Cons
  • The cooling system and work with Li-ion are considered a weak point.

The quality is at the highest level, be sure to try it.

Before that, I used only regular chargers for AA / AAA / 18650 batteries, and they just somehow charged. Faced with a situation of deep discharge of the battery - normal charging refused to charge (well, or charging had no effect). I've read reviews that not everyone can do this. Well, this one worked :) Got pros: It works well, there are several charging power modes, you can monitor the voltage, etc. Cunningly works with batteries of different types, you can just leave the battery overnight

I Love High Quality Battery Charger

only. This is a great smart charger. I had concerns reading another reviewer's comment which he sent back because when he read the voltage with his digital VOM it was very different from what the charger reads. I'm not an electrical engineer, but I suspect this has to do with the "pulsing" nature that this charger has to use to charge and discharge. I measured the charge and discharge voltage with DVOM BK Precision 2709LE, DVOM Harbor Freight and an old analog VOM. If the charger reads about…

Pros
  • High quality construction
Cons
  • Total available in black color

This saved me the hassle of buying new batteries!

A few years ago I bought AA and AAA Duracell and Rayovac Nickel Metal Hydride (NiMH) rechargeable batteries and a Duracell 2 cell fast charger. A few months later several batteries were showing up as 'defective' and it annoyed me that I had a bunch of batteries less than a year old that had failed. I spontaneously decided to buy this charger based on a few YouTube videos. and the charger's ability to test and charge cells individually. I figured it would also be a great way to test individual…

Pros
  • Impressive
Cons
  • Unsure

Excellent battery tester/charger

Package Contents: The device came with base station, power adapter and manual. , during and after use: Modes: 5 different modes can be selected to operate the device. Load, unload, update, test and quick test. It's great to have so many options for your batteries! Overheat Protection: The system has a built-in temperature control monitor and cooling fan and does its job perfectly. That doesn't mean you shouldn't keep an eye on your batteries, though. If you have a "heater" handy, the device…

Pros
  • Handsfree
Cons
  • Slightly dented
