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

I purchased this at a substantial savings. But besides that, it has way more reserve than my older 8amp battery, and the rubber accents really help protect it. This battery extends the use of my blower by about 10 minutes over the old one, doesn't get hot and charges up fast. So, function is excellent, price is good, quality is excellent, value is excellent (did I tell you I got it on sale?), can't speak to longevity, but it is name branded. If you need a new 8amp battery, this generation is very good. I recommend this as a buy.

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.

I really like this high capacity DeWalt battery. And the details for DeWalt sawzall's indicate that the higher capacity of this battery will provide higher power output from the sawzall than a 2AH-5AH battery will provide. Too, of course, the battery capacity will last a lot longer. The only downside is the cost.

The 8ah power pack works very well for my 6-1/2” XR circular saw as well as my 5” angle grinder. Lots of power and plenty of runtime. Highly recommend for high demand tools in the DeWalt 20v system

A true Dewalt battery that runs and runs. Very happy with the product. Don't buy the useless "generic" batteries! Remember, you get what you pay for!

I bought this for my DeWalt weed eater and it last a very long time ! Don't be fooled by bogus battery's that says Dewalt. I got took by bogus battery's before, check Dewalt website to see. I thought it might be heavy but when put into my weed eater it is balanced well and not heavy. All my tools are Dewalt and their customer service is excellent !

Powerpack batteries are worth the extra money they last longer and have more charges.

Works great, plenty of power

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

These batteries run a little wider and not as tall as the other ones. However, it's great and filled with power. If you're someone like me who was debating between this or the 5ah one, I'd say get the 5ah. The size, weight, and power are the perfect package.

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!

very good battery

This is a premium battery. At a time when the 5ah are seeming cheaper made, this is a well built battery, with extra details - rubber padding. Etc. It's not hugely bigger than a 5ah, but noticeably more powerful. Doesn't come on sale all that often, but can be found <200 once in a while.
