DeWalt just simplified its battery lineup, and the new naming throws a wrench into what used to be a straightforward buying decision. Powerstack and Powerpack are gone, folded into one 20V MAX XR line, with a new tabless DCB2105 5Ah pack on the way. If you own DeWalt tools or are starting a kit, what you actually need to know is which batteries fit which tools. That has not changed, and it’s the whole point of this chart.
Here’s the short version: every 20V MAX battery works in every 20V MAX tool, and FlexVolt batteries work in both 20V MAX and 60V FlexVolt tools. The chart below maps the platforms so you can buy a pack blind and know it’ll seat into whatever DeWalt you own.

| Battery Type | Sample Models | Fits 20V MAX Tools | Fits 60V FlexVolt Tools | Voltage It Runs At |
|---|---|---|---|---|
| 20V MAX battery | DCB210 2Ah, DCB205 XR 5Ah, DCB208 8Ah | Yes | Yes, full power runs at reduced output | 20V in 20V tools, ~20V in 60V tools |
| 20V MAX XR battery | DCB205 5Ah, DCB203 3Ah compact | Yes | Yes | 20V (XR is a performance tier, same battery interface) |
| FlexVolt battery | DCB606 6Ah, DCB612 12Ah | Yes | Yes | 20V in 20V tools, 60V in FlexVolt tools (automatic) |
| 60V FlexVolt tool | Runs FlexVolt OR 20V MAX batteries | Yes, at reduced power | Yes, full power only with FlexVolt pack | 20V or 60V depending on pack |
Read that across: a 20V MAX battery seats into any 20V MAX tool. A 20V MAX XR battery is the same interface, so it also seats into any 20V MAX tool and reads at the same 20V. A FlexVolt battery is the wild card, it mechanically fits both 20V MAX and 60V FlexVolt tools, and the tool reads the pack to decide the voltage. Drop a DCB606 into a 60V FlexVolt circular saw and it runs at 60V; put it in a 20V MAX drill and it runs at 20V. One pack, two speeds.
The One Rule That Covers Everything
Compatibility is about the battery interface on the tool, not the tier name stamped on the pack. Every DeWalt 20V MAX battery shares the same slide-in connector, so they all physically work in every 20V MAX tool. XR just marks the higher-output tier of that same connector. The only thing you cannot do is run a 20V MAX battery in a tool that only takes FlexVolt packs, and DeWalt does not make one of those, every 60V FlexVolt tool also accepts 20V MAX batteries.
Running a 20V MAX pack in a 60V FlexVolt tool works, but the tool drops to reduced power and shorter run time. If you own one 60V tool and a stack of 20V packs, you can buy a single FlexVolt battery and get the best of both.
The Naming Change: Powerstack and Powerpack Are Now XR
DeWalt retired the Powerstack (tabless) and Powerpack (pouch) names and is folding them into one 20V MAX XR line. If you own a Powerstack pack, nothing about how it works changed, it’s a tabless 20V MAX battery and still fits every 20V MAX tool. Same for Powerpack. The new tabless DCB2105 5Ah pack is coming and carries the same tabless construction with more capacity than the first-generation Powerstack packs.
What changed is the label, not the socket. A Powerstack-branded pack you bought last year still seats and charges like the XR pack you’d buy today. If you’re matching by model number, DCB208 and DCBP034 roll under the new XR name alongside the standard DCB205.
Which Battery Should You Buy?
If you mostly drill and drive, the DCB210 compact keeps weight down. If you run saws, blowers, or grinders, the DCB205 XR 5Ah is the sensible everyday pack. If you own any 60V FlexVolt tool or plan to, the DCB606 FlexVolt is the one that pays for itself, it runs those tools at full 60V and every 20V MAX tool besides.
Frequently Asked Questions
Do all DeWalt batteries fit all DeWalt tools?
Almost. All 20V MAX batteries fit all 20V MAX tools. FlexVolt batteries also fit 20V MAX tools and 60V FlexVolt tools. The pairing DeWalt does not make is a 20V tool that only takes FlexVolt packs, every FlexVolt-compatible tool takes both.
Can I use a 20V battery in a 60V FlexVolt tool?
Yes. A 20V MAX battery seats into a 60V FlexVolt tool and runs it, just at reduced power and shorter run time. For full 60V output you need a FlexVolt pack.
What is the difference between 20V MAX and 20V MAX XR?
Same battery interface, different performance tier. XR tools and packs are built to deliver higher sustained output. The battery connector and compatibility are identical, an XR pack works in a standard 20V MAX tool and vice versa.
Are FlexVolt and 60V the same thing?
FlexVolt is the battery family name, 60V is the voltage the pack delivers in a FlexVolt tool. A FlexVolt battery switches between 20V and 60V automatically depending on what it’s plugged into, and works in both 20V MAX and 60V FlexVolt tools.
Does DeWalt still make Powerstack batteries?
It’s the same tabless construction, now sold under the unified 20V MAX XR name. DeWalt retired the separate Powerstack branding, so new packs carry the XR label but the technology is unchanged. Older Powerstack packs still work in every 20V MAX tool.
How do I know if my DeWalt battery is compatible with my tool?
Check the battery interface. If the pack slides into the tool’s handle cavity, it works. DeWalt stamps the platform on the pack, and every 20V MAX pack fits every 20V MAX tool. For 60V FlexVolt tools, the pack needs the FlexVolt connector, which the FlexVolt batteries have.
