waitley20V 9.0Ah Lithium Ion Battery Compatible with DEWALT DCB200 DCB209 Tools with LED IndicatorRecycled Claim Standard Blended

I have mostly dewalt cordless tools with a couple Ryobi sprinkled in. I recently purchased an 18v Ryobi lawnmower - single battery. Using authentic Ryobi batteries, it took 2 fully charged 4ah batteries to cut my whole yard, and usually I have to slap on a small battery for the last pass or two. I had a dewalt to Ryobi adapter that allows me to use dewalt batteries, and I tried this out. I cut the entire yard, used my blower for a couple mins, and then used it in my impacts driver to remove and sink appx 100 screws, and still had 50% battery remaining. I have no idea how accurate that is, but it’s remarkable if it’s truly 50%

Works well enough in a lawnmower. It's 9 ah so it doesn't last quite as long as the 10 ah, but I've had no issues so far. Will update this if that changes.

Good alternative to more expensive Dewalt options. 8Ah Dewalt powerpack with tabless cells batteries are ~$150 and these can be had for around ~$50. Tested capacity when new and only pulled ~7.6Ah which is still a good deal for $50. I have these batteries for 1.5 to 3 years and they still work quite well after heavy use. Fully discharged at least 3 times a week. Will update with a recent capacity test on these batteries.

I’ve been very happy with the quality of this battery. It’s a significant savings over genuine Dewalt batteries and honestly I can’t tell a difference in performance. One nice feature that my Dewalt batteries don’t have is a digital battery level meter. A very nice upgrade for a lower cost battery. I purchased several of these and been happy with all of them.

These batteries didn't make it one year!!!! I used them thru the summer, stored them during the winter (off and on the charger) and they won't take a charge this spring. I bought 4 of these and 2 are completely dead.As much aș i hate to say this, save your money and buy a different brand. I can't get the seller to return an e-mail or call, amazon has not helped....I really got screwed buying these. This is the first time I have been really screwed on Amazon. the issues I've had in the past have always been resolved....not this time!!!

It fits the Dewalt tool mount with no slippage. Although a bit bulky it works well.

It works

This was such a a great bargain and it arrived fast, quality battery with long holding charge!!
