Upgraded Powerextra 3000mAh Replacement Battery for Worx 20V Lithium Battery, Compatible with Worx 20V Battery Charger and WA3520/WA3578/WA3525/WA3575/WA3671/WG151s/WG890, Replace for Worx 20V Battery

Usually don’t write reviews but felt compelled to do so on this product. Ordered this battery as a replacement for one that would not charge up anymore. This battery has more power than the previous two I purchased through Amazon. It also holds a charge much longer. I house is on a corner lot with a large backyard with a lot of flower beds that need edging. I am able to complete all the edging with one charge and then put the battery in my blower and complete blowing off my sidewalks and driveway with the same charge on the battery. This battery is a great value at it’s current price and one I highly recommend.

Replacement batteries are often so expensive that I end up buying a new tool on sale when the battery dies. I expected to buy a new tool. This was a good price and looked like OEM. Perfect fit.It seems to last as long as the OEM when I bought it new. I use this to get charcoal grill very hot for searing meat. Works great.Hard to beat.

This is a copy of the email I sent to Powerextra two times without a response.I purchased the: Powerextra WA3520 2.5Ah Worx 20 Volt Lithium from Amazon on April 18th. I am very disappointed in this battery. After charging the battery overnight, I put it in my WORX WG546 Cordless Blower. The issue is with the Powerextra battery is the blower will only run on low speed (will not run on high, just turns off) and only runs for 3 or 4 minutes. Recharging does not improve performance. The blower works on high and low speeds for 10+ (on high) minutes with my old battery.

A decent replacement for my Worx weedeater. It is 2024 and I have had these for at least 2 years.

I was concerned as to the ability for this battery to power my trimmer, but it did as well as the Worx battery. Maybe even better! The price was right and the shipping was quick. I'm glad I made the decision to purchase this battery. I would not have any concerns about this product at all. I looks like the original and works as good or better.

UPDATE:After making my first review, I contacted the company and they offered to give me a new battery without me even asking. Even though I declined, I felt that was very gracious of them and believe this now deserves a 5 star rating for going way beyond what was expected.First review: Purchase April 2019 - Absolutely dead March 2020... I have three batteries that I exchange when one is charging. This one won't take any charge... Good price, not so good product from my perspective... I think it should have last at least two years with the little use it experienced UPDATE:

Battery does not hold a charge as long as the original WORX batteries.UPDATE:: the company sent me another battery and it is working great! Excellent customer service. Would now rate them as a 5 star.

This fit my combo set to f trimmer and blower tools and though the battery feels lighter than the OEM battery it lists as more power and it definitely seemed like it on my first use. I was able to use my trimmer for what I’d guess was half again longer than the original battery and it had good power right til the end. My original purchase of the tools came with two batteries and one no longer works and the other seems to last about half its original time so this replacement seems great, even better than the originals! Hopefully it recharges many, many times. I liked it so much I have a second one on the way! And these are far cheaper than the OEM replacement batteries.
