Can You Use a 60V DeWALT Battery on a 20V Tool and Vice Versa?

DeWALT is a name synonymous with power, durability, and innovation in the world of power tools. At the heart of these tools are the DeWALT 20V and 60V Lithium-ion batteries, designed to ensure consistent performance and longevity.


Yes, you can use a 60V DeWALT battery on a 20V tool, thanks to the FlexVolt system. However, using a 20V battery on a 60V tool isn’t ideal due to power demands. For optimal performance, match the battery to the tool’s voltage.

DeWALT Battery Basics

DeWALT batteries are more than just power sources; they are the lifeblood of the tools they power.

20V vs 60V Batteries:

Parameters20V Batteries60V Batteries
WeightCompact (lighter weight)Bulkier (heavier due to increased capacity)
Energy CapacityStandard energy capacityHigher energy capacity
Ideal UsageEveryday tasks (e.g., drills, saws)More demanding tasks (e.g., heavy-duty equipment)
Run TimeConsistent power for standard tasksLonger run times, suitable for extended and tougher tasks

DeWALT FlexVolt system

The DeWALT FlexVolt system is a game-changer in the realm of power tools.

Here’s why:

  • Adaptability: FlexVolt batteries automatically switch voltage when you change tools. This means they can power both 20V MAX* and 60V MAX* tools.
  • Power on Demand: With the ability to provide either 20V or 60V, the FlexVolt system ensures that tools get the power they need when they need it.
  • Longevity: FlexVolt batteries not only offer more power but also longer run times, making them ideal for extended tasks.

Can You Use a 20V DeWALT Battery on a 60V Tool?

Using a 20V battery on a 60V tool brings its own set of challenges and considerations. While the FlexVolt system offers adaptability, it’s important to understand the limitations.


  • Power Deficiency: 60V tools are designed for more power-intensive tasks. A 20V battery might not provide the necessary energy for optimal operation.
  • Reduced Run Time: A 20V battery, with its smaller capacity, might deplete faster on a 60V tool.
  • Potential Strain: Continuously using a 20V battery on a 60V tool could strain the battery due to higher power demands.

Performance Outcomes:

  • Suboptimal Performance: The tool might not deliver its best performance, especially for power-intensive tasks.
  • Inconsistency: There might be fluctuations in power, leading to uneven results.

Interchangeability Between 20V and 60V Batteries:

While the FlexVolt system focuses on the 60V battery’s adaptability for 20V tools, the reverse isn’t always ideal. Using a 20V battery on a 60V tool isn’t recommended due to the challenges and performance issues highlighted.

It’s best to use the battery designed for the specific tool’s voltage for optimal results and longevity.

Safety, Performance, and Maintenance of DeWALT Batteries

Ensuring the longevity and optimal performance of your DeWALT batteries is closely tied to maintaining safety standards.

Storage, Maintenance, and Lifespan Tips:

  • Temperature: Store batteries in a cool, dry place. Extreme temperatures can affect battery performance and lifespan.
  • Clean Contacts: Ensure battery contacts are free from dirt or debris for efficient energy transfer.
  • Avoid Moisture: Batteries should be kept away from water and moisture to prevent short circuits.
  • Regular Use: Batteries benefit from regular use. Charge them every few months if stored for extended periods.
  • Discharge Strategy: Aim for partial discharges instead of fully depleting the battery to extend its lifespan.
  • Charging: Remove the battery from the charger once it’s fully charged to prevent overcharging. Ensure the charger is compatible with the battery’s voltage. Most DeWALT chargers designed for the 20V system can also charge 60V FlexVolt batteries but always refer to the charger’s specifications.

Signs of Battery Damage:

  • Swelling: A swollen or deformed battery indicates potential internal damage.
  • Leakage: Liquid or residue around the battery terminals means the battery should be replaced.
  • Overheating: Batteries can warm up during use, but excessive heat or smoke is a warning sign. Discontinue use immediately.

Final Thoughts

DeWALT’s FlexVolt system showcases adaptability in power tools. Users should recognize its limits and ensure compatibility.

Proper understanding and maintenance maximize the potential of DeWALT tools and batteries.
