K-KJ65KHA4BA Super Advanced 4-Position Quick Charger with LCD Indicator Panel, USB Charging Port and 4AA eneloop pro Rechargeable Batteries, Black

This charge means business! It can charge 4 dead lithium double AA batteries in just a few hours! Great for use with portable scanners!

Consistently Excellent Performance! No More Single Use Batteries!!!

Best charger I ever have. This charger gives indicator showing the charging progress, which is great. The charge time is same but that's expected. The battery refresh feature is very useful. I like NiMH batteries due to high safety and good-enough capacity, and I have over 100 NiMH batteries around, I lost track which ones are newly purchased and which ones worn and close to its end of life. The refresh feature would condition the battery and through the process, it measures the total effective capacity of the battery (a 2400mAh rated battery would show 2150mAh after a year)! That's very, very useful to me. I now know which batteries could be used in remote controller (consume less power) and which ones to put into kids toys (drain battery in hours), and which to ditch away. I don't use the USB output feature at all but hey that doesn't hurt either. Another positive mark - This charger is quite - some chargers have high pitch noise when actively charging, and that bothers me when I am working on my bench. This one is quite as a deck of cards. Not all chargers are made equal, and I am happy to say I found the right one for me.

Unfortunately did not provide enough time for further testing, however it charged fast, the charger itself felt like it was made well, & for the short time they were utilized, the batteries held a full charge. Due to no longer needing the product I purchased these batteries & charger combination for; I wound up returning these. However, should I need this battery & charger product combination again in the future, definitely will consider buying them again, but hopefully with a reason to keep them permanently.

I decided to spend a little more on these, and I'm glad I did. There's a lot of crap Chinese batteries and chargers on Amazon these days. We do cabinetry and remodels and are always needing batteries for laser levels and things like that so this is great for that.

The product seems to be very good. The battery drain function did not help me - some of them are faulty. Please note that an adapter is needed for those who do not have an American socket

The charger works great and worth the money. I have been using it for almost a month now and still no issue. Battery stays charged for the entire month without recharging. I will definitely recommend this product.

Good investment saves money in the long run like it displays percentage of charge and resets battery memory
