20V MAX XR POWERPACK 8.0 Ah Power Tool Battery (DCB2108)

I did not ***need*** this battery, but am I going to say "no" to 8 Ah of XR power goodness? I love DeWalt batteries in general -- I have several, some of which are probably at least 10 years old, and in my experience they are basically unkillable. I got this battery primarily for powering the cordless circular saw I (finally) got -- a saw will drain a 2 or 4 Ah battery pretty quickly, with any kind of heavier use. The one "con" so far is that the battery is a Reel Big Boi, for sure -- significantly larger than a standard 5 Ah battery, for example. You probably don't want this hanging off your drill, driver, or palm sander, unless absolutely necessary. But that's fine as I have the "normal" sized batteries for those applications.

Wow, am I impressed. This thing lasts forever. Love it!

OEM Dewalt batteries can't be beat, especially the Powerpack and Powerstack series. I was a little apprehensive about making the order because there are so many counterfeits out there, but this is an OEM battery, and the 8 Amp Hour batteries are great for a full day of runtime on my Dewalt circular saw, and I usually get 6-7 hours on the high setting on my Dewalt job site fan. The package arrived earlier than promised and that's another plus - a solid buy.

Bought this when it went on sale as well. So far great battery.

I purchased 2 of these grey 8AH DeWalt batteries (DCB2108). They're the grey powerstack type, as inside is a stacked, pouch-style batteries (vs. cylindrical cell). I chose this based on a review (ProjectFarm) that showed they outperform the typical DeWalt battery chemistry. I had 2x 10AH regular batteries for my lawn-mower. I chose to replace them with a new pair of these grey 8AH, they came with a low charge, I gave them a quick 45min recharge (not full, light was flashing) and then proceeded to cut my grass. It was a wet day, the grass was long, I went thru 5 bags of mulch off the back of the mower (vs. a typical 2 bags) yet the batteries still had life. No loss of performance! I made the choice to downsize the battery because one was taken from my unlocked car (it was attached to an inflator) so I had to replace with a matching pair...I balked at the price of 1x 10AH (regular type DCB210)...plus I think one of those really large batteries wasn't amazing...just couldn't remember which. As I write this review I see now the algorithm has put that older, larger, battery on a deep sale now...arghh, maybe I could have bought only 1 after all...oh well. Now either my trimmer or blower can have the old 10AH battery stay with it without removing them from the mower each time I switch tools!
