Customer Questions & Answers

Is a battery charger included with the purchase? or do you just plug it in and unplug it for use?

Just have seen this item on line.
Asked by: Timbo
Battery is removed to charge. The model from HD is LST400 which has 1 battery, the LST420 has 2 batteries. Last check I did was HD does not carry the 420.

How long does the battery take to recharge?

Asked by: Bandmom
Out of the box, the initial charge took about 10 hours. The next time I had to charge it, it took about 8 hours. I get about 1 hour of run-time before needing to recharge the battery.

Can this trimmer be reloaded with bulk trimmer line instead of having to buy Black and Decker specific replacement cartridges?

Asked by: dataway
Yes, but not recommended. Hard to get the auto feed system to work correctly if you do not get tension correct.

How many rechargeable battery does it cones with? I saw some other Black&Decker cordless trimmer that cones with 2.

Asked by: Raquel
the part number listed in replacement parts indicates this is a 2.0 amphour battery, but the information about this unit says 4.0 amphour. It is the same battery provided in the trimmer with two batteries. All such batteries are 2.0 amphour. Someone needs to fix this.

Rated 5 out of 5 by from Light weight and battery that comes with it lasts longer... Light weight and battery that comes with it lasts longer than it takes me to do my yard! Sure didn't expect that.

Rated 4 out of 5 by from Very good The biggest plus to this tool is the battery life. My last trimmer was a craftsman and....it was awful. Had to recharge after 15 minutes of use, tops. This B&D went for 35-40 minutes and still seemed to have plenty left. Unfortunately I was done trimming! Couple of downsides though. One, it is a slightly heavier unit. Does fatigue your forearms a little bit. Two, it needs more cutting power on edging, even in high. I have to go over some denser grass multiple times to get a good cut. All in all, however, this is a good unit and a significant upgrade, particularly on battery life, over my last trimmer.

I run into some problems with them so I ordered two more. Hopefully, I can repair the originals, but if I can't I am covered with the two new ones I ordered. I really like them as the batteries last for 45 minutes or more, and they are the right weight that I can easily handle being a woman and 71 years old. I have had no trouble interchanging the batteries as they are the same models. We have a five acre area that my husband mows so there is plenty of trimming for me to handle. I am very satisfied with this product and was greatly relieved to find that I could order the exact model again. Parts are available from Black and Decker if you need them.

Rated 2 out of 5 by from Bad battery I've used dozens of battery-powered tools and the battery /charger on this is among the worst. It flashes green for hours (charging )and then flashes red (problem with battery ). I haven't had time to address the issue with HD or BD yet but will. Power is not even close to a gas trimmer. It is light weight and will get the job done. ..eventually. Two batteries and a quick charge system would make it more tolerable. I can't say I'd recommend buying one. Probably better products out there for a few more bucks.

This trimmer filled the bill when I needed something lightweight for my sore arm. Easy to put together and worked well and for as long as I needed it to. My only complaint was that I wanted it to use the same 20 volt battery as my leaf blower and I did not have any way of determining that it used a 4 amp instead of a 1.5 amp battery. Another lesson learned, but like the trimmer very much.

The battery lasts as long as I need it, never measured the time, but at least a half hour. I can also use the batterys that came with my drill and hedge trimer, so I have enough battery power. Haven't tried the edging part yet. Probably use my gas trimmer for that.
