ELEFLY 5.0Ah WA3578 Replacement for Worx 20V Lithium Battery WA3575 WA3520 WA3525, Compatible with Worx 20V PowerShare Battery Tools WG163 WG170 WG261

This battery is larger, with better capacity and performance when compared to the WORX battery is was purchased to replace. Well constructed and initial use excess expectations.My initial battery did not work and I received a prompt replacement from the vendor. I was frustrated with the delay, but that was due to normal shipping times.

This fit my word weed eating just right! A lot of power and a lot cheaper then the world x battery

Does not last long enough in my word blower! Not very happy with it's longevity in my tools!

Good value for the money

Battery works as advertised. Have only had a short time but seems to work fine. His 5Shr battery gives a much longer run time than the original battery in my blower. No problem with fit or manufacture. Happy buyer.

Worked 3 times in 2 yrs and it's dead. The original battery that came with it still works great. Not this one I ordered. It's junk. Dead already. Company says it's too old to do anything about it and it's my problem and my loss. Don't expect much, that's all you get

Battery lasts longer and has more power than 2 smaller battery packs.

Great battery wish it had meter too tell you how much is left. I can use my trimmer about 25 min. Stock battery lasted about10 min or so. I would purchase again.

If this battery lasts for 6-7 years I will be very happy! At the moment it makes the run time on my leaf blower twice as long. Very happy!

Batteries jammed on my Worx snow blower. Very tight and I could not get them out. They fit into my Worx chain saw though. Seller willing to give me a partial refund in a short period of time.
