The charger runs each battery independently, which is awesome but doesn't seem to charge to the same capacity as our Duracell charger. After a few days, it also started to make a high pitched noise we could hear when walking past it in the kitchen. Still an all right unit for the price but I'll look at other units when this one is needing replacement.*Update 12/16/17* Customer service is excellent and the replacement charger fixed my issues. The new one is charging consistently across all 4 channels and doesn't make a high pitched noise like the first one did. Batteries now appear to be performing the same regardless of which charger they come out of (Duracell vs EBL) but this one can charge 3 at a time which I absolutely need since my headlamp is a 3 battery device. EBL will be considered for future purchases now that I know they support their product. That's getting rare these days.
