we are having trouble installing the battery pak.

Asked by: Davew6
Ours went on readily, can’t think of any reason for your predicament.  If it was forced in perhaps one or more of the connector pins on either side may have been damaged. If so try to straighten them out.  Good luck

Can’t really answer that as they came with the trimmer, however I would consider enquiring some stores that sell and repair those machines.

Can you wind your own string on or do you have to buy a new replacement spool every time it runs out?

Asked by: hedy49
You can spool your own string if you want however the automatic string advance may not work.

Need replacement spool. What info do i need to purchase replacement spool

Asked by: Dee D
The replacement spool is Black & Decker AF-100 and contains about 30 ft of line. You can also buy off brand spools online for about 1/4 the cost or if you want to reload the original spool you can buy .065 bulk line up to 300 ft at about 1/10 the cost.

Does it work with a B&D 2.0 ah Li-ion battery

Asked by: Paolo2
As long as the 2.0ah battery is rated for 20volts and if it fits into the battery slot of the trimmer, it will work, however your run time will be shorter.

Black & Decker Cordless String Trimmer/Edger - Adjustable Height - Automatic Feed Spool - 20-Volt is rated 3.9 out of 5 by 157.
Rated 4 out of 5 by from Good little trimmer for small yard This thing works great for a small yard. Mine is less than 3000 square feet and the battery easily does everything on high power without using the whole battery. Note that this does have a brush motor so not sure how long it'll last and it does make slightly more noise and vibration, but has plenty of power. I like the stand-off wheel for cutting against fences without beating them up with the string. This thing is minimum 2lbs lighter than the bigger 14-16" competitors, so it's a lot easier to use (and you could always get a bigger battery for medium size yards), but I would recommend looking elsewhere for big yards.

Rated 2 out of 5 by from Machine is great - batteries terrible I bought this last year to help with volunteer work at local parks, nature preserves, etc. I am a 70 year old male, short and 145 pounds, so wanted something light. The machine is great. Goes through vegetation like a dream. But the batteries -- and the charging system -- are HORRIBLE! I now have 5 batteries - two of 2.0Ah and 3 of 1.5Ah. They each last only a short while and it takes FOREVER to charge them - basically all afternoon and evening or overnight. If I was just doing around my house, 2-3 batteries would suffice. But for anything more, the battery system is pure junk. (I learned from a friend that his string trimmer (made by a different firm) has batteries that recharge in half an hour. What's going on, B&D? And, why have such small capacity batteries?)

Rated 3 out of 5 by from Good unit with a terrible feed mechanism Overall, I quite the unit, particularly the ease with which it goes from conventional trimmer to edger. And I like being able to interchange batteries with my other B&D gardening tools. But the automatic feed has never worked, not from day one, not with the original spool, not with new spools, not with hand wound spools. And the Dewalt/B&D repair was not able to fix it either, and hinted that "they all do that". So every few minutes, I have to turn it upside down and manually unwind some string, which gets annoying. With a working feed, I'd give the unit 6 stars out of 5. As is, I give it a generous 3 stars.

Rated 5 out of 5 by from Hard To Find But Does A Great Job This is my second B&D weed eater/edger. The first lasted for almost ten years. I have extra batteries and line spools so I searched for an exact replacement. I found this one and am very happy with it. I wish the weed eater/edger was available separately instead of having to purchase a kit that includes parts I already have. It would be nice if the description included the part numbers for replacement line spools and batteries. It would also be nice if the description provided line length and diameter as well as battery storage rating in milli-ampres/hour.

Rated 4 out of 5 by from Best Trimmer Have used this trimmer all year now on a .35 acre yard. 2 batteries does one 40 foot fence, around the entire house, one side of the garage, around the garden shed, 20 foot side walk, four trees and 20x10 porch. A 3rd battery will take care of a 100sq ft patch of grass I dont like to mow. I load one battery, put another in my pocket and off I go. I dont have to worry about gas or even finagling a cord around, just lock n load and trim. I have only one reason why this isnt 5 starts, while I have yet to change sting spools, every now and then I have to pull the spool and unwrap a bit of string that gets stuck.

Rated 5 out of 5 by from Great for what it is This is a great, light weight trimmer and does exactly what it is meant to do. I've read lots of 1 star reviews complaining about the battery lasting only 15-20 Minutes. I was pleasantly surprised that it lasted that long! Just think of running any of your power tools for 15 to 20 minutes straight...you couldn't. This 20V lithium battery has as much power as my old B@D, last a little longer and it is lighter. This trimmer is perfect for the person who mows their lawn once a week and then trims it. If you are a person who doesn't trim but a couple of times a year and the grass is getting pretty gnarly then this is not for you, you need a gas powered hog. Know what you are buying, set your expectation to a reasonable level and you will be very happy with this trimmer.

Rated 5 out of 5 by from The trimmer is underrated! Had a couple runs on the trimmer, expecting to have bad battery life, but no! This trimmer has an improved battery (2.5 Ah battery) and lasted for good 20-25 minutes at high power setting. Hope the battery will last long but I am having a lot of fun owning a trimmer for the first time.
Date published: 2017-07-03
Rated 5 out of 5 by from Great value for the price. I had the previous version for 5 years. This trimmer is much lighter and takes the older versions batteries. I'm not a B&D person but this trimmer is very nice. I highly recommend for medium yard work and trimming.
