Question: OVERHEATS! Came w/o inst. and no box-this thing overheats in 15 min SO HOT it's frightening! Think it is used and defective,any responses?
Document: I bought this gift off on my son's wishlist and it came with no Black & Decker box!! Does not make a very good presentation for a Christmas gift.
This unit charges faster and does two at a time for seamless weedeating. I think it charges better too. My batteries last longer than they did with the charger that came with my  B & D trimmer. With this setup I can trim until I'm tired of trimming instead of the battery telling me it's time to quit.
I am giving it a 5 star ,for the size and ability to charge 2 batteries at one time. I have not used the product yet, I hope I will not be disappointed. I have been dealing with Black and decker for years. This charger is replacing one that originally came with A kit I bought about 7 years ago. I used the heck out of it. got my moneys worth from it.
This product does its job well. It saves on the number of outlets needed and seems to charge the batteries at least as well as the single chargers that came with my tools. I have a fairly big yard with lots of sidewalk trimming. I can trim and blow the whole thing with two batteries if I'm really moving, four batteries are plenty even if I'm being really careful.
This dual capacity charger by Black and Decker seems to function adequately. My two major complaints are one, the charging indicator lights never go out. How can you tell the charging ccondition of batteries? And two, no documentation or instructions. I question the 'new' status since it came in a big Ziploc bag inside the shipping box. I really don't have a clue as to how how long to leave the batteries in the charger. Have tried to contact the seller with no success.
If you have enough 18v batteries to think you need this charger you also have enough of the free chargers you don't need this product.
works great. No problems. I used it many times already without any problems. Will recommend this to others as Ihave had good experience with it.
I own a grass hog trimmer and the blower combo. I charge two batteries at a time instead of 1 - my four that I have are always ready to be used to keep the lot looking good
Great deal on a great item. Used it to Replace two single unit chargers, less space, one less outlet needed. The price of this unit was less then the cost of buying two single units.
It may take a bit longer for 2 batteries to charge simultaneously, one battery at a time will charge faster. But, its just as good as I my single chargers. It works! and that's the important thing about it.
Answer: yes
