waitley - Lithium Ion Battery 20V Max 9Ah Compatible with DEWALT XR DCB200 DCB204 DCB205 DCB206 DCB209 DCD/DCF/DCG Series Tools with LED Indicator

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.
