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

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.

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

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.

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.

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.

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 Quality, Value for the money, For battery life if you have to make sure the battery is not Connect to a tool or a Parasitic Draw Happen.the battery what I mean is never let your battery Drain and get below 20% of charge if it happens than charge as Soon as possible to keep your battery in very good State. And if you don t do this then you made your battery last less than it Should!!!!! hope this help someone out there. P.S. make sure you have a good chargers DCB 1106 DCB 115 DCB 1104 DCB 118
