You guys motivated me to try one. I just bought the
Ryobi 40-Volt Lithium-Ion Cordless Attachment Capable String Trimmer
Home Depot $149
Hopefully my 12 year old son can handle it.
Ryobi 40-Volt Lithium-Ion Cordless Attachment Capable String Trimmer-RY40220 - The Home Depot

My 12 year old son could handle it fine but I guess I have too many weeds for a battery trimmer.
It lasted about 23 min we charged it and ran it again and we still are not done. I am going to take it back.

Its been 8 years since I purchased this trimmer. Just the other week, the charger stopped working on me. I think I'll crack it open to see if there is anything obvious, but I'm thinking I may have to replace it.

A few screws and it came apart. The problem was easy enough to find.

Here is the Ryobi P1113 lithium battery charger.

Four torx head screws on the bottom (under the rubber feet), and it comes apart.

Finding the damage is quick and easy. Notice the little plastic chunk.

This is where it used to be.

Amazingly, the body of the transistor or whatever it is was actually intact. I could easily read the part number of TOP247YN.

So, I checked digikey and mouser for this part number. It looks like they cost almost $5 for one piece. A new aftermarket charger costs $24 shipped. So, I think I'm going to go that route instead of trying to repair it. Who knows if the rest of the components are actually all okay still.





Interestingly enough, this charger actually has a recall going on for it. Ryobi has it posted on their website. Unfortunately, my charger is a later serial number and not eligible for a replacement.

Sometimes a bad battery will make a charger burn up like that.

I've been using this one for several years with no problems.
Kobalt 80-volt from Lowes

I had a 120v corded weed eater from 2008 to 2012 killed it, bought the same one again in 2013 and still have it.
A $70 black and Decker.
Now I have a 29cc Redmax.

Interesting. I'm going to tell our grounds guy about this.

Damn I just killed that 120v weed eater from 2013.
Got a 120v plug in troybilt.

Me too. Got a generic Ryobi 18 Volt 6.0Ah for the wacker and so far, my wife likes it.

So, this thing has finally kicked the bucket. It started making very funny noises and the string would randomly let loose. Turns out that the motor bearings are shot. You can wiggle the armature around way more than you should be able to. I tried looking for a replacement motor, but I'm really not finding anything. The best I can find is the P2003 motor which looks like it mounts the same, but its only a 10" vs mine which is the P2002 and its a 12". I may give it a shot. But, some of those higher voltage models are looking pretty good. I certainly wouldn't mind a bit more oomph as I tend to let things go before I get to them. Suggestions on a replacement are welcome!
