The delivery and service were outstanding, it took just over a month to get delivered to my door from China. The battery power is as good as the original and lasted just as long as the original EGO 5AH battery that I have. The new batteries are the older style which show a single green light when charged instead of the ones that have a segmented display to show a partial charge. The only thing that is a small issue is that once the battery is charged on the charger the fan keeps running, it will only stop if the battery is removed from the charger.
