How to Choose Your DeWalt 60V FLEXVOLT Battery

What Makes FLEXVOLT Technology Different?

A DeWalt FLEXVOLT battery changes voltage the moment you switch tools. Plugged into a 20V MAX tool, it stays at 20 volts. On a 60V or 120V MAX tool, it automatically shifts to full power. No manual adjustment is needed on site.

This patented technology also protects the cell from overheating and extreme cold. The 6Ah, 9Ah, and 12Ah models all share the same voltage switching. Only the capacity changes based on your runtime needs.

Which Capacity Should You Choose: 6Ah, 9Ah, or 12Ah?

The 6Ah suits occasional jobs and lighter tools like drills. The 9Ah balances weight and runtime for a regular full workday. The 12Ah targets heavy-duty use, like circular saws or grinders running for extended periods.

All three capacities share the same form factor and the same DeWalt charger. You can mix and match batteries based on the tools you're using that day, without buying extra equipment.

Which DeWalt Tools Work With FLEXVOLT Batteries?

FLEXVOLT batteries power over 200 DeWalt 20V MAX tools, including drills, drivers, saws, and grinders. They also work with 60V and 120V MAX tools that demand more power, like miter saws or industrial blowers.

One battery system covers your entire cordless tool lineup, from light to heavy-duty. That's a real advantage for crews switching tools several times an hour on site.

How Do FLEXVOLT Batteries Perform in Canadian Winters?

Lithium-ion cells lose some efficiency in extreme cold, but the FLEXVOLT design limits that drop through built-in thermal management. Tradespeople working outdoors in winter get a more stable start than with an unprotected standard battery.

Between uses, store the battery at room temperature rather than in an unheated vehicle. This simple habit extends its lifespan across multiple seasons of Canadian job sites.

Which DeWalt Charger Should You Use With a FLEXVOLT Battery?

A FLEXVOLT battery needs a FLEXVOLT-compatible or multi-voltage charger, never a standalone 20V charger. The DCB104 4-port charger lets you charge up to four batteries at once, a real advantage for crews running multiple tools non-stop.

Keeping a charged battery on standby avoids downtime on an active job site. Many professionals rotate between two or three FLEXVOLT batteries to avoid ever waiting on a full recharge.

Your Questions About DeWalt FLEXVOLT Batteries, Answered

Is a DeWalt 60V FLEXVOLT battery worth the price?

The higher price reflects the dual voltage and higher capacity. One FLEXVOLT battery replaces what would otherwise require two separate systems, 20V and 60V. Over time, the investment pays off for professionals running several DeWalt tools daily.

How do you know when a DeWalt FLEXVOLT battery needs replacing?

A runtime that drops quickly even after a full charge is the first sign. Unusually long charging times or a battery that heats up at rest also point to advanced wear. The LED gauge on the charging block remains the most reliable way to check actual cell condition.

What is the lifespan of a DeWalt FLEXVOLT battery?

DeWalt lithium-ion batteries are built for about 1000 full charge cycles before capacity noticeably drops. Avoiding repeated full discharges helps you reach that number. Actual lifespan varies based on how intensively it is used on site.

Can you charge a DeWalt 60V battery with a 20V charger?

No, a standard 20V charger cannot charge a FLEXVOLT battery to its full 60V capacity. You need a FLEXVOLT-compatible or multi-voltage charger to use both voltages. Check our DeWalt chargers selection to find the right model for your battery.

Do FLEXVOLT batteries work with the DeWalt 20V MAX tools I already own?

Yes, they are fully backward compatible with the 20V MAX system. They fit the same cordless DeWalt drills and drivers with no adapter needed. You simply get extended runtime, up to 6X longer depending on the tool.

How do you maintain a FLEXVOLT battery through a Canadian winter?

Avoid charging a battery that is still cold straight out of an unheated vehicle in deep winter conditions. Let it return closer to room temperature before charging. Store it away from freezing temperatures between job sites to protect the cells.

What is the difference between a FLEXVOLT battery and a standard 20V MAX battery?

The difference is dual voltage. A standard DeWalt 20V battery always stays at 20 volts, no matter the tool. FLEXVOLT automatically shifts to 60V on tools that need it, expanding its use to the most powerful saws and grinders in the DeWalt lineup.

Are DeWalt FLEXVOLT batteries covered under warranty?

Yes, they are covered under DeWalt's limited manufacturer warranty, valid in Canada. Keep your Équipement Polar proof of purchase for any claim. If you are unsure about eligibility, our team can walk you through the process.
