20V Max is just tells us what tools/batteries fit with nothing about their power, suitability, etc. Saying "Max" excused using peak instead of nominal voltage, but they also had to distinguish the 18v Li-Ion line from the older 18v NiCd line… then they were forced to call it "18V Max" in places like the EU. DeWALT's parent company went on to make "V20 Max" for Craftsman and Porter Cable. Truly evil!

"XR" was always supposed to be for their top tools/batteries. New tech has shifted the battery tiers so relabeling makes sense.

Originally "XR" on a tool meant pro grade brushless for extra runtime and reliability (daily use). In a battery it originally meant higher current and capacity, often from a second parallel set of 18650 cylindrical cells ("2P5S" = 10 cells).

The 8AH PowerPack XR (DCB2108) is using 21700 cylindrical cells but so was the 8AH XR (DCB208) it replaces. The Samsung INR21700-40T cells in the DCB208 are switched out for some new "tab-less" cells in the DCB2108. The "tabs" it refers to are internal to the cell so they should be the same physical size (21700) and capacity (8AH total) but higher current. Maybe now it'll finally hit harder than the 6AH XR with 10x INR21700-30T cells.

Yes, 30T is lower capacity, higher current compared to 40T. Those same monster 30T cells are in the 9AH FlexVolt (3P5S; 15 cells), which explains why it does even better in 20V Max tools.

One minor correction: PowerPack is launching with XR branding, not rebranding with it. Ignoring the "PowerDetect" and "FlexVolt Advantage" nonsense that's on the way out, the "boost" any tool might get from an XR battery is usually just that they could've used the extra current all along.

For increasing current at the same voltage:
Different formulas in the same physical cell size can trade capacity for current (30T>40T>50S).
Physically larger cells increase current (21700 vs 18650).
More parallel cells increase current (6P5S 15AH FlexVolt with 30x 18650 cells versus 2P5S 5AH XR with a third of the same cells).
Tab-less cells increase current (8AH PowerPack XR versus 8AH XR).
Stacks of pouch cells with their wide tabs increase current (PowerStack).

There is an ID pin that distinguishes old 1P batteries from higher current (generally 2P+) batteries but even that doesn't align with the XR/non-XR badging or any of the PDetect/FV Advantage stuff. Heavy duty tools probably use it to reject a 1.3AH battery from a Black Friday drill bundle.

Distilling all that down:
6AH XR, 9AH FlexVolt, and 5AH PowerStack have been the beasts of the 20V Max line for a couple years now. We'll see if the new 8AH PowerPack XR will join them.

Eventually we'll get the AI-enhanced Pro Plus Max Ultra HD Double-X Platinum S 5G Red Edition Prime and it'll blow everything out of the water!

Probably getting thumbed down for the use of key words, but i agree that this looks to be a great price; $15/ah is unheard of on these powerstacks. Thanks for posting.

It's still in the 20V Max line and there is no PowerStack-specific charger so all 20V Max chargers should charge PowerStack.

Mine both came with one bar remaining on the charge indicator. One is currently on the basic (and ubiquitous) DCB107 and the other is on a revised DCB118 (two-stage fan-cooled 8AH fast charger). Both were charging fine when I left to work.
By law, if you want to ship lithium ion by air, it must be max 30% state of charge, so it probably left the factory with only one bar.

In a way, yes. It's optimized for power (think sprinter) whereas regular ones are optimized for energy (think marathon runner). In a high power tool, it perform like a larger battery until it runs out of juice.

Makes sense for battery packs which can over-discharge or go out of balance when stored unused for long periods.

Always charge a fully drained battery ASAP! Lots of people leaving fully drained batteries over the winter find they won't take a charge when they need to use the blower, trimmer, or mower for the first time in months.
Yes. I have been involved in several fire investigations that were attributed to charging old batteries that were left uncharged for extended amounts of time.

I got them on black for for $75 each with free shipping. I use them on my 20v impacts.

It's a tiny bit more than a new look: They are introducing the new "PowerPack" with tab-less cylindrical cells. Despite being newer they are not replacing the PowerStacks with stacked lithium pouch cells. Indeed, the 5AH PowerStack still outperforms the 8AH PowerPack.

The Home Depot just might be silly enough to move 'em out for style/rebranding but that's a huge hit to take. There's a fresh round of claims that they are dropping DeWALT all together but I've been hearing that for two years now.
I finally decided to start on putting together a more cohesive tool setup, and understanding the battery technology is the hardest part of the whole process. Major PITA.

20V Max, XR, Flexvolt, Flexvolt Advantage, Power Detect, PowerStack, PowerPack, and the 20V is the same as the 18V, just using peak vs nominal voltage.

From what I understand, DeWalt's revamping all their battery lines. I THINK this is the new setup, but don't quote me...
  • All the current batteries (with 18650s?) will lose the XR name and be 20V Max.
  • There's something about dropping the Home Depot - Lowes specific tool lines lines (Power Detect vs Flexvolt Advantage) and relabeling those tools XR. (I wonder if this ruffled HD's feathers)
  • The PowerPack (21700 cells?) and PowerStack (pouch cells) will all get the XR moniker (no PowerStack batteries, just PowerStack XR).
  • Flexvolt (which I guess is actually "Flexvolt Max"), will stay the same.
  • So...
    • There will be no "plain" 20V batteries, only 20V Max.
      • So, "Max" means nothing, as it's the lowest "level" of the battery lines.
    • The XR is now about power/current level (based on the battery type) and not "eXtended Runtime," and gets tagged on the the PS and PP lines.
      • The "plain" PowerStack and PowerPack will become PowerStack XR and PowerPack XR.
      • So, "XR" means nothing, since these are already named differently.
    • XR tools will get a boost from XR batteries, while Max tools will not.
    • XR tools might get a bigger boost from Flexvolt batteries than XR batteries, even though they aren't "Flexvolt" tools.
Does anyone know if this is right?

I look forward to the upcoming 20V Max XR PowerStackPack Max XR Flexvolt Max XR Tournament Edition Director's Cut Max XR batteries with Kung-Fu Grip! (And here I thought that CPU naming was peak stupidity. Little did I know...)

Yeah, and they say it's better for the battery if you aren't storing it at full charge too. I've heard something like 70% is ideal for long term storage? Not sure, but if you just charge it to full and throw it in a warehouse it's not ideal in more ways than just potential for fire. Like, the state of charge will drop more dramatically over time or something.

MAX* will accompany all DeWalt tools and batteries that claim a higher voltage than nominal. Flexvolt are MAX*, XR are MAX*, Atomic are MAX*, Xtreme are MAX*, 60v are MAX*, 20v are MAX*, 12v are MAX*, they are all MAX*.

The moniker and its accompanying asterisk is what allows them to advertise stuff as being a higher voltage even though it really isn't. This is the text behind the asterisk for "20v" tools:
* Maximum initial battery voltage (measured without a workload) is 20 volts. Nominal voltage is 18.
This 20v/18v confusion (now expanded to 60v and 12v) started as a way to distinguish between their Ni-Cd and Li-ion batteries, with the bonus of many consumers incorrectly assuming that their 20v Max* Li-ion batteries were higher power than other companies' 18v Li-ion batteries.

Thanks! Was the clearance price $75 for you too?

Edit - Just checked several around me (Atlanta OTP south). In addition to Newnan, GA ($75) I found:
Carrollton, GA (no go)
Villa Rica, GA ($75)
Douglassville, GA ($75)
Lithia Springs, GA ($75)
Peachtree City, GA ($75)
Fayetteville, GA ($75)
Morrow, GA ($75)
Riverdale, GA ($75)
Jonesboro, GA ($75)

Hit rate is pretty good on the ATL GMA south side.
Thanks for the inventory check. Repped you. 👍🏼

Julian - thanks again. You def know your battery info. I screen grabbed all that info. 👍🏼👍🏼

I tried repping you again, but SD won't allow it (too soon after initially repping you). 😯

good luck trying to find these, went to local one that said had 7, they had 0 lol... i ironically ran into someone else trying to find same deal last week. Battery lady took me to 3 different places around store and they had 0... she was like we could have had 0 for a long time and inventory never updated

Forgive my ignorance but I don't use dewalt tool due to limited budget. But with a name like "powerstack" you'd expect to be able to... stack the batteries together. I just think it's a funny name.
