DeWalt’s PowerPack 4Ah Is 60% Off After the Rename

Amazon listed DeWalt’s 20V MAX XR PowerPack 4Ah battery, model DCB2104, at $67.80 on October 13, 60% off the $169 list. A two-pack (DCB2104-2) was $119, or $59.50 a pack, against a $269 list.

That looks like a dead-line dump. DeWalt’s own U.S. page already titles the same SKU as a 20V MAX XR 4Ah pack, because PowerPack is a stamp coming off the plastic, not a cell type leaving the 20V MAX system.

Amazon Listed the PowerPack 4Ah at $67.80

The single DCB2104 on Amazon carried a 4.6-star average from 166 ratings and showed more than 1,000 bought in the past month. The two-pack held the same 4.6 average from 144 ratings, with more than 4,000 bought, and sat as the Best Seller in Cordless Tool Battery Packs.

The 60% cut is not a one-day glitch. Listings were already at 60% off on October 8, during Amazon’s big sale, and they were still there on October 13. Deal hunters who waited for Prime week and shoppers who arrived later are looking at the same PowerPack-branded carton.

THE OCTOBER SHELF

• Single pack: DCB2104 at $67.80, down from $169, 4.6 stars from 166 ratings.
• Two-pack: DCB2104-2 at $119, down from $269, which is $59.50 each.
• Volume: More than 1,000 singles and more than 4,000 pairs bought in the past month on those listings.
• Standard 4Ah: The DCB204 on the same listing is $62.99, 4.6 stars from more than 4,600 ratings.

A $5 gap between tabless 4Ah and the older round-cell 4Ah is the whole pitch. In March 2026, DeWalt 20V packs hit $36, more than 70% off, in Amazon’s Big Spring Sale, so another round-cell dump can still undercut this if you only run light tools.

The Same Cells, a New XR Label

In August 2026, at DeWalt’s Built Black and Yellow event in Baltimore, the company told tool testers it was dropping the PowerStack and PowerPack names. Kenny Koehler, who was there covering the battery desk, came back with a flat line on what actually changes.

The technology isn’t going away. Rather, this is primarily a rebranding to help simplify how Pros select batteries.

Kenny Koehler, after DeWalt’s Built Black and Yellow event in Baltimore

On DeWalt’s U.S. site the DCB2104 headline is already “20V MAX XR 4Ah Battery.” The box contents line still says PowerPack, which is how you get a $67.80 Amazon carton with the old stamp next to a factory page that has already moved on.

The logos had started disappearing in April 2026, when product photos and pack art lost the PowerStack and PowerPack marks and grew the XR type. Standard 20V MAX packs lost XR on the shell at the same time, so XR now means the premium tier, not a specific cell.

HOW THE NAMES CAME OFF

1. April 2026: PowerStack and PowerPack logos leave DeWalt site photos and pack art, with XR set larger.
2. August 16, 2026: In Baltimore, DeWalt maps the 4.0Ah PowerPack to 20V Max XR 4.0Ah and the 8.0Ah to XR 8.0Ah.
3. August 2026: A new DCB2105 5Ah tabless pack is slated to replace the 5Ah pouch pack; 1.7Ah and 3.5Ah pouch packs stay.
4. October 8, 2026: Amazon is already running the PowerPack 4Ah at 60% off in its big sale.
5. October 13, 2026: The single DCB2104 lists at $67.80 and the two-pack at $119.

Tradespeople who already mix XR, PowerStack, and PowerPack packs on one charger treat them as one 20V stack and shop by amp-hours and size. The tax lands on anyone buying from a photo, because the words that used to mark pouch versus tabless are the ones DeWalt just painted over.

Pouch, Tabless, and Standard Now Share XR

DeWalt did not collapse three designs into one. It put two premium designs, plus the word XR, on the same shelf language. PowerStack packs use stacked pouch cells. PowerPack packs use tabless round cells that send current through multiple paths instead of one welded tab. Standard 20V MAX packs keep older round cells and, after August, no XR badge.

For the five premium packs already shipping, amp-hours do not overlap, so a 4.0Ah XR pack is still the tabless DCB2104 and a 3.5Ah XR pack is still the pouch DCBP320. That cheat dies when the 5.0Ah tabless DCB2105 lands beside whatever 5.0Ah pouch stock remains.

OLD STAMP TO NEW SHELF NAME

Model numbers still sort the drawer. Standard packs are DCB plus three digits (DCB204, DCB205). Pouch XR packs are DCBP plus three digits. Tabless XR packs are DCB plus four digits. If the listing only says “20V Max XR 5.0Ah,” you have to read the model before you pay.

What the DCB2104 Still Puts Out

The DCB2104 is DeWalt’s tabless 4Ah pack for 20V MAX tools, rated 20 volts off load and 18 volts nominal, with a 3-LED fuel gauge and an overmolded base. DeWalt’s U.S. product page claims 50% more power than the DCB240, not in a tool test, and a longer life counted in charge cycles against that same pack, with a 3-year limited warranty, 1 year of free service, and 90 days to send it back.

The DCB240 is the older 4Ah cylindrical 20V MAX pack, the baseline in that 50% claim. Amazon’s DCB204 at $62.99 is the other 4Ah shoppers actually see beside the PowerPack, and it works on the same 20V MAX tools. You do not need tabless cells for a compact drill you pick up twice a weekend.

You do want them on a circular saw, grinder, or reciprocating saw that pulls hard enough to heat an older pack. DeWalt still says one 20V battery runs more than 300 tools in the system. A Farm and Fleet spec sheet says the DCB2104 fits every 20V MAX tool and charger and does not fit FLEXVOLT or 12V MAX. The same sheet puts the pack at 5.71 by 2.72 by 5.08 inches. Acme Tools lists an assembled weight of 1.4 pounds and Mexico as the country of origin.

Pouch packs, not this one, are the compact story. DeWalt’s own “compact size” line is written for PowerStack, whose 1.7Ah DCBP034 is the pack electricians keep on an impact driver in a tight box. The DCB2104 is the mid-size tabless pack, not a stubby.

A Pair Costs Less Than One Did

At $169, one DCB2104 was more than double a sale-priced standard 4Ah. At $67.80 it is $4.81 above the DCB204’s $62.99, and the two-pack undercuts even that math.

LIST VERSUS OCTOBER 13 AMAZON

Two branded PowerPack 4Ah packs for $119 is less than DeWalt used to ask for one. If you already live on 20V MAX chargers, the pair is the cleaner ticket, because $59.50 a pack is under the DCB204’s everyday price and still the tabless 4Ah.

The 5Ah Pouch Pack Is the One Being Replaced

The DCB2104 is not the pack DeWalt is actually retiring. In August 2026 the company showed a 20V Max XR 5Ah tabless battery, model DCB2105, and said it will replace the XR 5Ah pouch pack. The compact 1.7Ah pouch and the 3.5Ah pouch stay in the lineup, which matches how pouch cells earn their keep: small tools, less bulk, overhead work.

The new 5Ah uses tabless 18650 cells in the familiar 5Ah brick, not the shorter, wider pouch brick. People at DeWalt’s 2026 Black and Yellow event said it should cost less than the pouch pack it replaces. Until it ships, a 5Ah XR listing can still be a leftover pouch DCBP520 or, later, a tabless DCB2105.

That is the second-order mess the $67.80 DCB2104 sidesteps. Four amp-hours still maps to one tabless SKU. Five amp-hours will not. Buyers who want pouch compactness should be shopping DCBP034 or DCBP320, not this Amazon 4Ah, no matter how cheap the PowerPack stamp looks.

Who Should Pay $68 for Tabless Cells

At $67.80, the DCB2104 is a tabless 4Ah with a fading name, still under the 3-year limited warranty, still on every 20V MAX charger you already own. It is a bad way to “upgrade” a kit you barely use, and it is a good way to feed a saw that already browns out older packs.

BUY IT, OR WAIT

• Pay $67.80: You run grinders, circular saws, or recip saws on 20V MAX and want tabless 4Ah without the $169 list.
• Pay $119 for two: You already own the chargers and need spares; $59.50 a pack undercuts the DCB204’s $62.99.
• Skip for now: You only drive screws and can wait for another spring sale like the $36 20V packs in March 2026.
• Buy a different SKU: You want a stubby for overhead work, which is the 1.7Ah pouch DCBP034, not this 4Ah.

Read the model number, not the XR badge. A PowerPack logo on a DCB2104 still means tabless 4Ah. A plain XR 4Ah with that same model means the same cells after the stamp comes off. A 5Ah XR without a model is the listing to walk past until DCB2105 is actually on the shelf.

The $67.80 carton is leftover art on a pack DeWalt still sells. The name on the yellow shell is what Amazon marked down. The cells inside are the ones the XR 4Ah page is already describing without saying PowerPack.
