DeWalt FLEXVOLT Battery Compatibility
DeWalt FLEXVOLT batteries are a dual-voltage innovation: they automatically switch between 20V and 60V depending on which tool they’re inserted into. This makes them backward compatible with the entire 20V MAX ecosystem while also powering DeWalt’s heavy-duty 60V tools.
TL;DR
- FLEXVOLT batteries automatically switch between 20V and 60V based on the tool.
- FLEXVOLT batteries are compatible with all DeWalt 20V MAX tools.
- Standard 20V MAX batteries are not compatible with 60V or 120V FLEXVOLT tools.
- Two FLEXVOLT batteries used in compatible tools deliver 120V operation.
- Compatibility confirmed by the official DeWalt FLEXVOLT system page.
Compatibility Rules
According to DeWalt’s official FLEXVOLT system page, FLEXVOLT batteries are compatible with DeWalt 20V MAX tools. When inserted into a 20V MAX tool, the battery automatically switches to 20V output. When used in a 60V tool, it delivers 60V. This one-way backward compatibility is a key advantage of the FLEXVOLT system.
What It Is NOT Compatible With
| Platform | Compatible? | Notes |
|---|---|---|
| DeWalt 20V MAX tools | ✅ Yes | FLEXVOLT auto-adjusts to 20V |
| DeWalt 60V MAX FLEXVOLT tools | ✅ Yes | Primary use — delivers full 60V |
| DeWalt 120V tools (in pairs) | ✅ Yes | Two batteries needed |
| DeWalt 12V MAX | ❌ No | Different platform and connector |
Charger Notes
FLEXVOLT batteries can be charged with DeWalt’s standard 20V MAX chargers as well as FLEXVOLT-specific chargers. Multi-port chargers (DCB104) can charge multiple batteries simultaneously. Always use a genuine DeWalt charger to protect battery cells and warranty.

Compatible Tools List
DeWalt FLEXVOLT batteries (DCB606, DCB612) automatically switch between 20V MAX and 60V MAX depending on the tool they’re inserted into. This means every FLEXVOLT battery is fully backwards-compatible with all 20V MAX tools. FLEXVOLT-specific tools run at 60V for maximum power. There is also an 80V MAX configuration using two 40V adapters in select tools.

Frequently Asked Questions
Do I need FLEXVOLT batteries for FLEXVOLT tools?
Yes. 60V MAX FLEXVOLT tools require FLEXVOLT batteries — standard 20V MAX batteries cannot provide the required 60V. However, FLEXVOLT batteries can also be used in any 20V MAX tool, where they automatically switch to 20V mode. This backward compatibility makes FLEXVOLT batteries versatile across both voltage platforms.
How does FLEXVOLT switching work?
FLEXVOLT batteries contain cell groups that automatically reconfigure between parallel (20V, higher Ah) and series (60V, lower Ah) connections based on the tool they are inserted into. A 20V tool triggers parallel mode (e.g., 6.0Ah); a 60V tool triggers series mode (e.g., 2.0Ah). The switching is automatic and instantaneous.
Which FLEXVOLT battery is the best value?
The DCB606 (6.0Ah/2.0Ah) is the best starting point. It provides strong runtime in both 20V and 60V tools. The DCB609 (9.0Ah/3.0Ah) is better for sustained 60V use. The DCB612 (12.0Ah/4.0Ah) and DCB615 (15.0Ah/5.0Ah) are for professionals who need extended runtime in demanding 60V applications.

What is DeWalt FLEXVOLT?
FLEXVOLT is DeWalt’s dual-voltage battery system. FLEXVOLT batteries automatically switch between 20V and 60V depending on the tool they are inserted into, allowing one battery to power both standard 20V MAX tools and high-demand 60V tools.
How many FLEXVOLT tools does DeWalt make?
DeWalt offers over 30 FLEXVOLT 60V MAX tools including table saws, mitre saws, circular saws, grinders, rotary hammers, and outdoor power equipment. These tools deliver corded-tool performance without the cord.
Do FLEXVOLT batteries last long?
FLEXVOLT batteries have similar cycle life to standard 20V MAX batteries (1000+ cycles). In 60V mode, runtime is lower since the battery is running at higher voltage. A DCB606 (6.0Ah at 20V) becomes effectively 2.0Ah at 60V.
