Worx WA3555 56V 2.5 Ah Replacement Battery

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.

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 Amazon. 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!!!

Battery performs equal to the original batteries.

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.

This is an OEM replacement battery and based on the performance of my batteries that came with blower it should last for many years! Sadly the manufacturer has discontinued this item so I had to buy it from this company out of desperation. I gave in 4 stars because the price is oppressive! I am grateful I could get one but it was less money from the manufacturer! Have to take what you can get!

charged right up works great

Battery is a good replacement for the original battery, hold a long charge and seem like it will last.

Seems the same as thr original. It asts about 20 minutes
