waitley 20V 9.0Ah Lithium Ion Battery Compatible with DEWALT DCB200 DCB209 Power Tools with LED Indicator (Not Made in Dewalt)

Amazing battery after over a year of use. Long battery life. Great quality. I use on my heat gun, pressure washer and drill and it works amazingly. Will buy more.

I've got 3 of these and they seem to hold up well. Never any issues with charging or use. I had a 6mah from the same brand that would only charge halfway after about a year of use. But these and my other 6mah never had the issue.

Got two of these for a DeWalt mower because the price for DeWalt brand batteries is about three times more. They may not last quite as long per charge and they seem to shut down from overheating faster than the OE ones but those trade offs are worth it given the dramatic price difference. Can’t say how they’ll hold up over time but so far they’re fine. Also, the numerical charge-level indicator is much nicer that the DeWalt’s simple three-bar one.

Iv had the 6ah version for roughly a years its been awsome so I ordered the 9ah for a grinder. 2 things iv noticed 1 being the ah rating is a little less than advertised 2 once u get almost out of battery the tool acts sluggish unlike the dewalt that doesn't loose any power it just dies. Would recommend really good battery for the price point

When I first purchased the battery, I was able to easily clean my driveway, sidewalk, and patios after mowing, with at least 50% battery life remaining. But after approx. 10-20 uses, the battery life began to decrease noticeably. Before long, I was rushing to complete the job before the battery was depleted. I used the battery to run my 20v grinder a few times and after one such use, without abuse, the battery was extremely hot to the touch, instantly dropped to 0% battery life, and has never taken a charge again, after months of trying periodically. I’m convinced it’s fried at this point., I’m is extremely disappointing. I didn’t use the battery more than once per week and it only lasted a few months. I may just have to go back to the name brand batteries.

Excellent battery life, doesn't really weigh the tool down that much more. Has a digital battery gadget on it push a button and see what percentage of battery life remaining. Charges up Excellent on my original Dewalt charger. Same charger for 2.0ah battery as using on my new 9.0ah battery fast charging no complaints whatsoever highly recommend. Great price compared to the Dewalt battery prices could buy 2 or 3 to 1 Dewalt. Excellent quality great performance.

Good quality. Long life. I don't have a DeWalt 9.0 AH, so I can't make an actual comparison of the charge time, but it runs a lot longer than my DeWalt 6.0 AH battery.

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%
