【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

Appears well made, charged up OK, changing level indicator is helpful.

Grabbed this 2-pack of 6.0Ah 20V batteries for my Worx snowblower and wow — these things got power. I ran through heavy snow, and they held up like champs. No drop-off, no random shut-offs — just steady juice the whole time. They fit perfectly, charge fast, and last way longer than the originals. I was honestly surprised how strong they are for the price.

I never realized how greater capacity batteries make all your tools work better than before aside from longer lasting advantage. Both my Worx blowers now have my respect for their abilities. Yes I recommend getting these batteries even though they are a little pricey. Only issue I have is that charging takes an unusually long time.

I was skeptical to buy these, but I'm glad I did. So far they've been great. They're lighter than the original Worx batteries, but they last just as long as the original. Let's see how they do overtime. I use them for my lawnmower and they get through it without having to recharge in between cuts. I like that these are a lot cheaper than the original ones. I'm really happy with my purchase

I would give it five stars, but I have not owned it long enough. It fit in both my charger and my Weedwhacker effortlessly. It charged up and I’ve been using it and using it and using it. I love the fact it’s a smart battery and gives you an indication of how much charge is left. Normally you never want to discharge a lithium ion battery all the way down because it can promote the creation of dendrites. So far, everything is great.

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!

Runs good same as works brand and shipped to me fast 👍👌

These are not a worx battery but in the description it said they would work on the Worx products. With being able to get two for the price of one. I bought these and realizing they were cheaper to purchase than to go to the Worx website. Unfortunately with all the companies that make tools compatible with their batteries. You are at any companies mercy when you need battery backup. I don't mind buying but when batteries are as much or as close to the price I feel like they are gouging their customers. Thank God for Amazon I found these batteries and they are larger than the ones that usually come with their tools is another game changer. I could buy two on a deal and ended up giving one of them to a friend and kept the other for myself. I will be buying again
