waitley 2 Pack 20V 9.0Ah Replacement Battery Compatible with Dewalt Tools

These work well in our DeWalt tools including our blower and string trimmer. They give you much longer run time than the standard DeWalt batteries and are much cheaper!

Really pleased with theses battery's. They hold up well with in my dewalt blower . And a blower is a battery eater.

I don't have a actual DeWalt 9 amp hour battery to compare these against so let me just tell you what I got. I purchased three two packs of these batteries. It takes three batteries per weed wacker to have all day use On my 20 volt we weed wackers. The batteries last about 1 and 1/2 hours. And they take 3 hours to charge fully. So you can imagine that if I have three batteries, and I've always charging the ones that I'm not using, that I can run the weed wacker indefinitely. Overall even though I can't compare against an actual DeWalt battery, for the price I don't think you can go wrong. They fit correctly and easily. One last thought. I did have the large DeWalt for battery battery charger that I was using to charge these. It has a lot of power and still took three hours to charge the batteries. Not sure if you would get the same result if you're using the regular little charges that come with DeWalt tools

I really like this brand of batteries. Their construction is solid, and their performance is right on par with their claims. This is my first 9 amp hour aftermarket DeWalt battery, and I'm glad I went with this brand. I really like their smaller capacity batteries as well. These 9 amp hour batteries really perform well in my 100 CFM DeWalt blower, and my new 500 CFM blower, letting me blow leaves for over 30 minutes using less than half the charge, and other things that pull high amounts of amperage. These things are a great value for the money you spend, and they're reliable enough that I don't worry about them. I'm really pleased with this brand, and they'll probably be my go-to for the foreseeable future.

Nice batteries. Run time is what you'd expect out of a 9amp hr battery. Two of these run my 16" saw for about 4 hrs of firewood cutting and splitting. I ran out of grass before my trimmer shut off so honestly idk how long it runs a dewalt weed trimmer. I put one of these in a small framing circular saw and cut all day without even thinking about batteries. It's definitely nice to have a cheaper alternative to the over priced dewalt batteries. These 9 amp hr batteries I bought were my second purchase from waitley. I also bought a big pack of ghee 6 amp hour batteries. They worked well enough so I bought these for bigger projects. I let my buddy do some work on his crawl space with my 6 amp hr batteries. They came back covered in mud and scratches but they work like new. So I'd say durable enough for the buddy to borrow them.

I will start by saying, for the price, you can't beat these batteries.💯 I bought three of these batteries to use primarily with my 225 watt DeWalt power inverter and my 18" DeWalt job site fan. They are advised as "9ah" batteries, but, during my testing, I discovered that they are only 7.5ah, still very acceptible for a DeWalt compatible battery under $50 each. I used my DeWalt inverter with a 56 watt fan connected to it for testing. I have a Genuine DeWalt 8ah battery that I used for a baseline. The DeWalt 8ah battery would run the fan for exactly 1 hour and 55 minutes, while these batteries would run the fan on the same setup for 8 minutes less, meaning they are right at 7.5ah. I did the same test with 2 of the three batteries I purchased and got the same results both times. They are an excellent battery for the price, but they are not 9ah.

WOW, these things work great, last long and power your tools to be stronger. No costly dewalt batteries for me.

Lasted less than a year, before the display said they were at 100%, but wouldn't hold a charge, then failed to charge at all. Opened and half the 18650 cells were bad.

Batteries are quality but the seller took a very long time to ship them to me and kept trying to get me to do a refund so I could try to purchase it again at a higher price point.
