Review: These replacement batteries are a significant upgrade over the factory ones that came with my Worx 40V trimmer. They hold noticeably more power—I was able to trim both the front and backyard at full trigger power for about 40 minutes, and the battery indicator only showed a single bar of depletion. Very impressed with the performance and longevity so far!
Review: Good product at a very reasonable price

## Questions & Answers

**Q: Do uou charge before use?**
A: yes

**Q: What is the lifetime of the battery using it once monthly until it is discharged. Does is last for years? Thanks.**
A: I've only had these batteries for about a year. They still work. During lawn care season I use them once or twice a month, they only last about 20-30 minutes, so go right on the charger after use.

**Q: Do you charge these before use?**
A: I charge them only if they’ve sat for a while without use

**Q: Can you use the Worx charger to charge these batteries or new charger required?**
A: If your charger belongs to Worx 20-volt lithium battery charger, then our this WA3525 lithium battery can compatible with it.
