Black & Decker 8 Inch 12 Volt Cordless String Trimmer And Edger #CST800 Logo
Anonymous Posted on Jun 15, 2010

I've owned this great little Black and Decker CST800 grass trimmer for 6 years and only use it in Montreal summers (5 months long). Just this past week, I brought it in to recharge it and left it for 5 days on the charge. I went to use it last night and I barely got going when it started losing power. How long is the battery life in this machine? Is it worth replacing or buying a new trimmer? Thanks, Geoff.

    Thanks very much for your input. It's a sealed unit from what I remember, I'll have to look at it and see if there are removable parts to get at the battery.

How do i get the battery off a black and decker grass hog

Look for a black button on the end, push down and the battery should pop out a little ways enough to grab a hold of.

Black and Decker 2 HP Lawn edger

Ditch that old switch, and buy a better quality switch from HomeDepot or RadioShack that will suit your need. I personally ran into that same problem and brought a 2HP GP switch from HomeDepot. It works way better, than that stock swicth. ( It may require a little modification to the body though.)

Does not automatically feed out line

I am a bit upset. I purchase a Black and Decker Trimmer and you guys want to charge me almost 10$ to give me a little bit of advise on a problem. Than I find in that email that if I have fixed the problem you want me to email you and tell you how I did it. FOR FREE. Well I did fix it. If you would like to know how mail me 10$. Only fair.
