Biswaye 2-Pack WA3525 20V 4.0Ah Lithium Battery - Replacement for WA3520 WA3575 WA3578 Batteries, Compatible with WG163 WG183 WG261 WG779 20V/40V/80V Lawn Mower Blower Trimmer Outdoor Cordless Tools

These rechargeable batteries fit my Worx string trimmer perfectly. They stay charged for a good while before having to be recharged. Definitely a great choice at a great price.

When I read the reviews of this device one of the complaints was the batteries did not stay charged long enough so I purchased an extra pair.

Works well in my weed wacker.

Nothing not to like, and everything to like. They fit my Worx tools and work just as well for less money.

I recieved these batteries in early August. I was not able to use them until the last week of August. They do not hold a charge. The return date has now closed and I have two batteries that are worthless. Seller, if you could contact me to work out a way I could return the defective batteries, that would be great!Other reviews were saying that these didn't hold a great charge...but then some said they did. I guess I got the ones that don't.Not Happy With My Purchase

Works good after charge.

They work. Don't know how long they will last yet

GOOD QUALITY AND FAST SERVICE
