ELEFLY2 Pack WA3525 20V 4.0Ah Lithium Battery Compatible with Worx 20V Battery WA3575 WA3012 WA3525 WA3520 WA3578, Compatible with 20V Cordless Tools

I went to start up my Worx lawnmower (3 years old). No power. Immediately went to Amazon and ordered the replacement batteries. The next day I was up and running (and mowing) Also save a lot of money in the process. Highly recommend !!!!

Perfect replacement for original batteries. slid right in and held a great charge

I have an older craftsman grass trimmer and hadn’t used it in a few years. When I went to get a battery for it seems like the trimmer is now “obsolete” so then the long tracking of what battery replacement. So I took a chance on these and so far this whole summer they have worked great. Can’t say that for the dewalt replacement batteries I’ve bought for blower. They didn’t even last a season. Probably why I’m so excited about these.

On time and worked well on my works weed eater.

The media could not be loaded. I’ve only used it a couple of times for my weed whacker. Never left it on the charger just used it normally a couple of times. I stopped charging. One still works but this one does not charge. I’m waiting for the other one to fail now.

Not the best batteries, doesn't work very long doing a job

They are compatible with Worx tools. They are available since Worx batteries are always out of stock!The charge lasts a long time like a new one should. They are less than half the cost of the Worx ones.I think it is a great purchase.

good value quality product
