## Questions & Answers

**Q: will this battery work on the jawsaw?**
A: Correct, this listing will be compatible with the WORX 20 volt JawSaw.

**Q: Will wa3578 replace a wa 3520**
A: Yes, both batteries are 20 volt and are interchangeable, only with other 20 volt WORX tools.

**Q: Can I use this singular battery (with a power share device) along with a 2.0ah battery at the same time?**
A: Yes, as long as the two batteries are 20V. Keep in mind the runtime will be based on the 20V 2Ah. We recommend using 2 batteries with the same amperage for best results and runtime.

**Q: Does the battery come with a charger (either normal or quick charge) or just the battery alone?**
A: Just the battery. I bought a fast charger at the worx website.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great battery!
*by P***S on June 22, 2025*

Lasts for almost an hour with my Worx chainsaw. Charges pretty fast and has unstoppable power.

### ⭐⭐⭐⭐⭐ Honestly surprised - 1yr review
*by M***Y on October 16, 2023*

With all the junk that's out there in the world I didn't have high hopes for this battery. I bought it as an xmas gift last December and has been used all summer long. It really does last a long time and no detectable loss in performance. Slots in the Worx tools nicely, positive click when its seated. Really cant find anything different about it when compared to the worx branded batteries.

### ⭐⭐⭐⭐⭐ Used with a string trimmer, and now I can actually get the whole garden done
*by C***K on September 11, 2022*

I have a Worx string trimmer that came with a 2AH battery. That original battery always ran out about 80% through using it. This 4AH battery easily lasts the entire job, and I still have the 2AH one in reserve. It seems to be a pretty well-made pack, and the cells inside are hopefully quality and long-lifetime.It was pretty expensive, but that's the way these power tool companies work now. Cheap tools, expensive batteries.SPECIAL NOTE: I tried a cheap "6AH" Chinese knock-off no-name battery before I bought the name-brand one, and it wouldn't even charge with the official charger. When I took it apart and tested the 18650 batteries inside the knockoff Chinese battery, they corresponded to an overall battery pack that had about 2.5AH (not 6AH), so even if it had worked, it wouldn't have been worth the price, as it was about the price of a 2 or 3AH battery. Also, the reason it wouldn't charge was that the battery management system board was dead on arrival. Long story short, I do NOT recommend buying the knockoffs. They overstate their capacity, they use mediocre cells, the electronics in them are cheap and unreliable, and they are probably dangerous as a result. If you are strapped for cash, you might as well just buy the name-brand in a "lower" capacity.
