Question: I have a trimmer model NST2118...will this charger work on mine??? thanks
Document: I ordered two of these because my batteries are always dead I have put both chargers to use and so far they work Great These chargers are an Excellent Product Thanks..........
I have two batteries with my Black and Decker trimmer so I ordered another charger and keep them both charged up. Works out just fine for me.
I had actually lost mine in the move. I liked it so well I ordered another one. Of course, it surfaced again. Now I have 2 that I really like and can keep up much better. It is compact and delivers the charger.
Read about product and it was clear that it was what I needed. Order item and got it in 4 days. Great resource for equipment needed. Many thanks for quick response.
product arrived on time,as advertised and in perfect condition.i bought a grass trimmer which came with two rechargeable batteries but only one charger.i did not want to wait 9 hours before using it again so this charger works great especially if you have a bigger garden area to take care of.
Can't wait to start using this charger. These 18 volt batteries, when discharged, take a long time to re-charge and this spare charger is going to make charging the two batteries that came with my B & D Line Trimmer a lot less difficult. Good price, delivery and packaging. Very happy.
I had a B and D 18 volt charger die on me and needed to replace it. I had this model included in a different purchase. So when I saw it on Amazon at a reasonable price so ordered one. The charger works great as long as your not in a rush to get your battery charged. From 2 volts to full charge takes between 7 to 9 hours. I have 4 batteries and 2 charges so charging time is not an issue for me. The charger has a green light to let you know is charging, and shuts off when the battery is fully charged.
Works perfect! My weed-whip came with 2 batteries and only 1 charger.Now I can charge both at the same time.
Unfortunately I ordered the wrong charger. But returning it and ordering the right one was quite eaily accomplished.
I bought this charger to replace the original 18V charger which came with the drill. This replacement works as described. Who can ask for anything more?
Answer: yes
