## Description

The WORX WA3555 56V Li-ion Battery is a 2.5Ah battery that works with the following WORX 56V Tools: WG191, WG291, WG391, WG591, WG771, WG772, WG773. The 56V Battery provides gas-like power to your yard tools and the 2.5Ah gives you enough run time to get the job done. Since all of the tools in the 56V Lineup run off the same battery, the WORX Power Share program allows you to go from one tool to the next with the same battery.

Review: Great system, but discontinued as of June 2020 - I've owned a Worx 56V mower for five years now, and it's performed great on just the two original batteries through many long mowing seasons here in Texas. But I knew the batteries would inevitably lose some capacity, or may even fail, over the years, so I finally pulled the trigger and ordered two of these replacement/backup power packs. I had hoped the price would fall in the time I've owned the mower, but no such luck. Nevertheless, these batteries are truly solid. They sit in my shed through 110F summers and 25F (and colder) winters. They sit idle on the chargers for days, weeks, even months between use. They charge quickly, retain their LED charge indicators (though they run a lot longer than expected after the one light starts flashing), have circuitry to prevent overheating while charging (e.g., if I throw it on the charger right after using), and they still have enough life five years in to mow my yard (probably 30+ mins runtime to do my 3000 sq ft of St Augustine). I'm glad I bought the mower when I bought this house (literally no maintenance or repairs beyond blade sharpening), and I was about to say I'm glad the batteries are still available for this platform, but I see they have now been discontinued. So...I sure am glad I picked up a new pair when I did. Here's hoping I get another 5+ years out of the four packs I've got and the mower they power.
Review: One more battery changes lawn mowing cycle!!! - I've been using Worx battery powered lawn mower for 5-6 years. From the get go, I was able to cut front and back yard at once (about 8000 square feet combined, not totally squared - need to maneuver couple of tricky spots which require more efforts). Since last year, battery life has been diminished and I had to split lawn mowing duty in two-day span. Two-day task jeopardized my weekend life - less my time., but more yard work time... So I decided to purchase extra batteries. Unfortunately, there is not much option available (Worx website did not have any available inventory) and I purchased the last available one thru desertcart. I was unable to test how long the new battery could last in more scientific manner. However, I was able to complete front and back lawn mowing task in one try - well, I need to replace one during the halftime (front/back transition) and recharge the drained battery for the final push. New battery actually outperformed 5-6 year old batteries. Once another batch arrives, I am going to buy one more new battery so that I don't need to swap batteries multiple times. Happy yard work!!!

## Questions & Answers

**Q: Where can I buy a charger for the 56v worx**
A: I use the charger that came with the unit.

**Q: Does battery indicator lights light up during operations?**
A: No...you have to press a battery indicator light.

**Q: Can someone share with me please how long does this battery last if you use it with the blower full power?**
A: I haven't timed it, but it's not a long time, I'd say 20 to 25 minutes or so.  More important, it only lasted two seasons, that's total usage of about 4 months and now is won't charge, now to replace it costs $129.000 without the charger!  You might as well buy a whole new blower.

**Q: Can I use this on a 20v leaf blower?**
A: Definitely not.

### ⭐⭐⭐⭐⭐ Keeps my old mower running
*by R***T on January 3, 2025*

My original batteries have started failing and these new ones work just fine. Two of these make my mower run like it did when new. My lawn has about an extra front yard worth of territory to mow. Two of these new batteries and what is left of one original battery lets me get everything done if I don't let the grass get very long. These batteries have the power to do longer grass but will require a second charge for me to finish everything.
