【NEW LED Indicator】2Pack 6.0Ah 20V Replace Battery for Worx 20V Battery Compatible with Worx 20 Volt Lithium WA3520 WA3525 WG151s WG155s WG251s WG255s WG540s WG545s Cordless Power Tools Battery

Bought these for my mom for replacement for Worx batteries and so far they are performing flawlessly. She said, wow! these last a long time on her worx weed eater. They work on the original single charger and they also work on worx double charger.

Perfect backups for my Worx 40v mower. Definitely last a bit longer than the originals, and a necessity if 1 set isn’t quite enough to get all your mowing done, as was my case. Very pleased!

Worx has great products with interchangeable battery. This Hedge trimmer worked great right out of box.

The indicate light does not work but the battery holds a charge for a half hour. So it’s fine

Perfect replacement for my OeM batteries. With this extra set I am able to cut my grass in one go. These last longer than the ones that came with it too. Love that they are much cheaper. So far so good!

First thing first, completely ignore the Ah capacity printed all of this item. I get no way near the battery output of power on these when compared to the Worx OEM batteries that came with my Worx lawnmower. The product fit is compatible with all my Worx PowerShare tools (mower, trimmer, blower), as well as the OEM dual charger so at least that was correct. It also removes easily from the tools and chargers just like the OEM... another plus. That's where the positives end. The charge speed is about the same as the OEM, so I am not sure where that extra 50% of Ah capacity magically goes. I have had this product since the end of May and noticed it did not function as expected after the first use in June. My mower would rev up for no reason even on low grass. The speed also seemed a bit slower. I said to myself that maybe it was just my paranoia. I wished I had listened. Fast forward to today when I was cutting my lawn, the mower just stopped less than 15 minutes into my job. I looked at the battery indicators and I had 2 of 3 lights so I was confused. When I tried to start the mower again, it would start and then stop shortly after. I was starting to think maybe there is something wrong with the mower (which is only 3 months old). Nope, it was the battery. When I put the OEM batteries in the mower spun right up and was alive again for the next 30 mins or so to finish the job! I placed these batteries in my trimmer and they worked long enough to finish edging my entire property. This indicates that there was indeed juice left in the batteries. Just not enough to power the mower. Which leads me back to the 6.0 Ah claim. This effectively is a lie. There is no way that a set batteries supposedly more powerful than my OEM batteries couldn't power my mower. The batteries worked at least 3-4 times before this incident. Every time providing less and less run-time. I made up an excuse for the product like "oh maybe the grass was wet" or "maybe I was walking slower this time than last time I mowed." No! These are inferior batteries. Don't let the price fool you as they are definitely NOT a good value for money if they only last less than 2 months! Read many of the other 1* ratings and you will see others experienced exactly what I did. I should have listened, but now I am outside of the 30-day return window. I do have a set of non-OEM batteries that has a "red" sticker instead of the "orange" on these. I got them from a different Amazon seller. Those seem to be going well with no issues so far (*knock on wood*). They look almost exactly the same so it seems they all come from the same Chinese factory. Good luck!

Excellent

Not great. Could only cut about 3/4th of a small-ish back yard. They charge fully and they work, but the OEM batteries are significantly better. I should have just bought OEM spares to begin with. These are just ok. If "ok" is good enough for you, then these work. But for a 40v Worx brand lawnmower... That's a no from me.
