ArthurElizondo –
It charged my 18650 batteries to 4.5. There were 2 weak batteries & 2 good ones. All charged to the same high level. The adjustable slots are sturdy and scroll easily and tight. I also like the fact that you can just 1, 2, 3 or 4 batteries at a time. The lights indicate which batteries are charging and which have reached a full charge. Great product.
