Batteries don't last. New batteries don't work

The battery is no longer good. You will need to buy a new battery. Don't over charge your batteries. They all vary. Expensive cordless tools will come with a charger that shuts off automatic to prevent over charging. I own cheap Skill drills that has served me well. These batteries lasted over 11years. It makes no sense. They should not have lasted more than 5 yrs., even 2yrs. I make sure I never over charged them, but they should not last that long. Freaky. Your battery is dead forever, sorry. I have others just like yours waiting to be recycled.

Batteries wear down over time. The cells inside them don't work as well at holding a charge compared to when they were brand new. So after using them for a while they begin to last a shorter amount of time.

Lithium Ion batteries last longer and don't wear out as quickly. NiMH batteries are next in reliability. And NiCad have their own issues.

should be able to use a charger that you would use on a car a lawn mower battery only last 2 years 3 if your lucky if you don't have a charger it might be cheaper if you buy a new battery

maybe you are using too many functions. Try removing everything you don't need or you could get a new battery they don't last forever. Another tip make sure you flatten the battery regularly and then recharge to full from time to time.

Let your computer run out of battery(until it shuts down) then plug it but don't turn it on... let it charge for about 2 hours. Post here if it worked.

It sounds like your battery has died. The batteries don't last forever and they eventually start to hold less and less charge. Did you notice the battery starting to last a shorter and shorter time? You probably need a new one.

Now,I'm not sure because I don't work on bikes 2000 and later. Why? Because they have a ECM control in them. The ECM draws a certain amount of current. This should be in the milliamp range and will not pull a good battery down for many months. If you want to measure the drain, disconnect one of the battery cables. Using a Digital Volt Ohm Meter, set it up to measure AMPs. Touch one lead to the battery post and the other lead to the battery cable. If the meter reads a negative number, swap the leads. It will read how many amps the ECM is drawing. It will probably be something like 0.0XX amps. If it's over 1 amp, I'd suspect a problem. But, keep in mind what I said to begin with, I don't work on these bikes.

Good Luck

I had one of these a while ago, the batteries are just cheap. Trimmers also use a lot of energy and battery powered ones aren't the best way to go if you want them to run a long time. I highly recommend replacing it with a good gas or plug in model from your local hardware store, they can help you find the right one to fit your budget. If you don't want to get a new trimmer you are going to be fighting dying batteries every year.

Your battery is shot. I had one of these, the batteries are really cheap and don't last long. If you can afford it, ditch the Worx and buy a quality trimmer at your local hardware store. If you are short on cash you can buy new batteries online.
