20Volt 3500mAh WA3525 Battery Replacement for WORX 20V PowerShare Lithium Battery WA3520 WA3578 WA3575 Cordless Tools WG155s WG545s WG584 WG322 WG779 WG163

So far so good have only used this a few times. seems to be quality made merch.

Works great! Good snug fit and came with a good charge on it. Output is great..used it on my leaf blower and it had great power. Nice rugged casing like the OEM worx batteries. Doesn't have a charge indicator button/light like some of the newer word batteries do but all around can't complain it's great replacement battery and works like a champ!

This 3,500 mAH battery works great in all my Worx chargers and tools from drills to saws.I wish this battery had a charge indicator that would tell you how much battery is left when you are using it. Even without a charge indicator, this battery is a much better value than the name brand Worx batteries. It also has 75% more capacity and lasts longer than the standard 2 AH batteries that came with my tools.Workmanship, materials, and quality of this battery is top of the line.So far so good!

My Worx leaf blower can suck a 2Ah battery dry in about 20 minutes. This 3.5Ah battery allows me to do my back patio, entryway, sidewalk, driveway, and curbs and still has some juice left in it! The size and weight of this battery is about the same as a 2Ah battery, but this one definitely has more stamina.

I purchased a leaf blower at the end of last year and only used it once before packing it away for the winter. I have a large yard so I knew I would need an extra battery to make it through the yard even though I have very few trees. That's why I ordered this battery, plus it was cheaper than the Worx brand battery.Out of the box, the initial change was quick. It powered my blower, but the battery didn't last as long, in my opinion, as the one that came with it. If you don't need power for long usage periods, you probably wouldn't notice it as much. This might be a better option for a different application, like a drill.

I got to replace the battery for my blower since it couldn't hold a charge anymore. It fits perfectly and lasts enough for a decent amount of time. May get another one for long jobs but will probably wait a bit to see if this battery has a decent shelf life.

Good points: I have a couple of Worx jawsaws. I have found that having extra batteries is a must. This battery worked flawlessly with the jawsaws. It also charges just as fast as the Worx batteries. I have not noticed any decrease in power with this battery in comparison to the Worx batteries. The price is excellent.Bad points: None.A very good buy all around.

I used it with my worx mini vacuum and it died within 7 mins. I thought it was because of the vacuum shut off because it was too hot. But when I replaced it with a original worx 2.0 battery it didn't shut off even after 10 mins of continued use and that battery wasn't even fully charged. So I suggest you spend that few extra dollars because I think that will be a better investment.
