Question about Worx GT WG150 10 in. 18 Volt Cordless String Trimmer w/ 1 battery

Open Question

I bought a worx WA3512 18V line trimmer a few months ago. It worked beautifully and charged up fast. Lately it runs for only a few minutes and then stops. I tried just leaving it to "rest" overnight-then put it into the charger and left it charging overnight. Same problem-runs only a few minutes. This is very frustrating, to say the least. I have to have a trimmer-as I have many walkways and edging to do. HELP!

SOURCE: is the battery for the worx 18v string trimmer

All you have to do is check the sizes of the batteries. If they are the same size, by that I mean shape and dimension, there is no reason you cant use them on different equipment. ...Lee

SOURCE: The WORX triimer battery is

Make sure the battery and trimmer's contacts are clean- use a qtip and isopropyl alcohol, or a pencil eraser, or fine emory cloth, if corroded or oxidized. This could be a cracked, loose, or corroded connection anywhere in the wires or power feed, including the switch. If the battery is getting old, it could charge, but not hold enough juice and run down quickly. Measure the battery after it's charged, and then try to start the trimmer, and measure it again. If it's dropped, it could be a bad battery. A motor can short out, but that's the last thing to suspect. Here's what one person said in a review on

y GrampaSmo "Grampa" (Maryland USA) - See all my reviews
This review is from: WORX Air WG541 18-Volt Cordless Blower/Sweeper (Lawn & Patio) The blower is ok but the battery does not last more than 5-7 minutes. I called Worx and they replaced the battery but it still does not work more than 7 - 10 minutes. Worx said I needed to recondition the battery by draining it totally then recharging (4 times) and to always drain fully before putting back on charger. This did not work. When I asked Worx for my money back they told me they couldn't do that at this time (even though the product is under the 2 yr warranty timeframe).
Bottom line: don't waste your money. Product is POOR.

Not encouraging, but hopefully it's just dirty terminals.
Good luck, and hope this helps.

SOURCE: I am having problems with the battery on my worx

You can determine exactly what is going on by using a small handheld voltmeter. They are inexpensive, easy to use and come in very handy. Just test the output of the charger (after noting what the volt-output-rating is) by touching the leads of the meter to the terminals on the charger. If the charger is working at all, this is not a dangerous test. Conversely, test the output of your batteries by touching the leads of the voltmeter to the terminals on them. I suspect the charger is bad because after they overheat, they quit working and some don't last very long. I don't think YOU are doing anything wrong, just maybe the companies that manufacture these 2 electrical products are.

I used it yesterday and today it will not start. Battery is full charge. Button key is in place.

I would first take a meter and test that the battery actually charged. If that tests out fine ( should read at about 12.8 to 13.5 Vdc), I would then check all the wired connections to make sure they did not come loose.

My battery does not hold the charge, i will charge it for 24/hour and it only last 5 minute, why is that, iI buy this product for wife when went to Iraq, and when i talked ton her on the phone three months...

NiCad batteries have this problem when they are recharged frequently after being only partially discharged. This is also the case when the batteries are left in the charger continuously - even if the charger is described as being "automatic". I have old 12v batteries that I have been using for 20 years, but I only charge them for a few hours, and only when they have run down enough to be useless. I prevent leaving them too long in the charger by using a timer that cuts the power to the charger after a couple of hours. A couple of years ago I bought new drills and chargers, and believed that the chargers would be automatic and so could be left plugged in. Those batteries only lasted a couple of years, while the old ones are still going strong. I now use the timer for any of these chargers, automatic or not - but I had to buy new batteries first. good luck, Al K

My trimmer wont start. thought it was battery put a new one in worked for a few minutes and then stopped working

your batteries aren't charging fully, check them fully charged with a volt meter,, fully charged they should have a reading of 18.5 volts, if not they are not charging, and either the batteries have used up their life, or your charger is on its way out

My trimmer does't work longer then 20 minutes. I can only get part of my lawn done. it takes 3 days to get it done with my trimmer.

I hate to have to break the news to you, but it probably never will. The batteries sold with the Worx trimmers are very cheap. I recommend either buying a few extra batteries and keeping them all charged so you can finish the job or buying a gas or plug in trimmer.

I had one of these last year and there is just no way you are going to get any more out of it. Sorry.

I would get the phone number of the place you bought the trimmer from your discover card bill if you do not have the phone number somewhere else. Then call the company which you bought the trimmer from. Chances are the machine is under warrenty and they will give you a new battery or whatever the machine needs.
