"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!

Of course, it's not exactly the time that kills them in storage, it's over discharging… whether that comes from being stored several years new in the package, from an internal BMS powering itself from one bank of cells, or from a season of storage after being drained to the cut-off voltage in a tool.
You are wise to avoid potentially over-discharged batteries in the supply chain, but no factory-sealed 5AH PowerStack should be suffering that fate at this point. They've only existed a year and a half.
In the end. 20V Max is just the baseline for what batteries fit what tools and says nothing about their power, suitability, etc.
It's interesting that they are dropping "XR" from so many batteries but it kinda makes sense when it was always supposed to be for their top tools/batteries… DCB210 and the first XR mowers not withstanding (don't even get me started!). It was weird that 5AH PowerStack didn't have that badge and the 5AH 20V Max XR did. Their top tier has shifted so the labeling should too.
Originally "XR" on a tool meant pro grade brushless for extra runtime and reliability. In a battery it originally meant higher current from a second parallel set of 18650 cells (2P5S). These days you can get that kind of current from a single row of high current 21700 cells (1P5S) or a small stack of pouch cells.
The 8AH XR PowerPack (DCB2108) is using 21700 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… which is higher current. The "tabs" it refers to are internal to the cell so they should be the same 21700 cylindrical form factor. Maybe now the 8AH will 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 current 30T cells are in the 9AH FlexVolt which explains why it does even better in 20V Max configuration (3P5S with 15x 30T cells).
One minor correction: PowerPack is launching with XR branding, not rebranding with it. I haven't even seen one yet.
Rules of thumb:
Lower capacity cells with comparable chemistries can increase current (30T>40T>50S).
Physically larger cells can increase current (21700 vs 18650)
More parallel cells can increase current (15AH FlexVolt versus 5AH XR with the same cells).
Tab-less cells increase current (PowerPack versus traditional 21700 cells).
Stacks of pouch cells with their wide tabs increase current (PowerStack).
There is a pin that electronically 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.

6AH XR, 9AH FlexVolt, and 5AH PowerStack have been the beasts of the 20V Max line for a couple years now and the new 8AH PowerPack XR might be joining them. It displaces the old 8AH XR for sure.

I guess a large part of my confusion was the battery monikers appearing in tools that don't require the matching battery. Also, Flexvolt vs Flexvolt Advantage vs PD broke my brain for a while.
All I know is that we all better stock up on batteries before they move to a subscription model or microtransactions!
The larger HD by me was OOS, so it might be worth checking the smaller locations.
In the north Chicago burbs:
19 at Glenview
0 at Deerfield
39 at Randhurst
18 at West Niles
7 at Niles
10 at Evanston
0 Vernon Hills
For Chicago proper, all gone except:
10 at Brickyard
2 at Lincoln-McCormick
"limited supply" at North Ave

The difference is typically strength (current) versus stamina (amp-hours). An 8AH XR (DCB208) has more stamina but less strength than a 6AH XR (DCB206). A 5AH XR (DCB205) and a 5AH PowerStack have the same stamina: 5AH. Taking advantage of the greater strength means a faster discharge for a given capacity… but also more work done in less time.
Think: driving giant lag bolts successively into wood without each drastically slowing as they get deep. The PowerStack will help with that. If all we are doing is powering a folding retractable LED hood light (DCL045), the 5AH PowerStack and the 5AH XR should perform the same. Heck, that one even accepts smaller 12V Max batteries.
I guess you could say it's more time-efficient.

So seems they will have some marketing overlap w/ prismatic and tabless on the top end XR will remain the bread and butter, and non XR entry.
I will never buy a prismatic cell w/ the decades I have spent w/ RC, portable battery, and motor automation they never end well. Tabless OTOH I will wait until they bake for a while and prob dip in.

Chervon's "FLEX 24V" takes advantage of being higher voltage and higher current to give it an edge against traditional 18v platforms. Stanley-B&D and TTI can't sit idly by which is why we have DeWALT 20V Max PowerStack and Milwaukee M18 FORGE shoehorning them into existing tool/battery platforms. Hopefully they've all taken appropriate measures to ensure it is safe.

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.
