Real Fast Charger !!!
I was looking for this one for a long time. Finally, I got it from Amazon at the same price. Mine came with total black- even The word"WORX" was black too. So I bought orange and white spray paint cans and went to work to paint those letters in white and those two side bars with orange- just like the company's logo!! It looks fantastic.
Any way, this one save lots of time as it takes only 30 minutes to 5 20 Volt Max batteries I have. Great buy!!!

BEST ANSWER: To install the battery on the charger put the battery in until you hear a click and the battery is on the charger snuggly. The bottom light should turn on when the battery is charging and once it is charged the upper green light will turn on. The battery is fully charged within 45-50 minutes.
