Power Tool Batteries: Different Voltage Platforms

When it comes to choosing a replacement battery for your cordless power tools, the voltage of a particular battery will determine its overall operating torque. The higher the voltage rating, the higher the power. For example, a 12V battery won't offer as much power as an 18V battery for a cordless power drill, but a 20V battery will provide more power than an 18V battery.

Cordless Tool Batteries: Li-Ion, NiCad and Ni-MH

There are three main types of power tool batteries, each with unique advantages. Below is a basic overview of Ni-Cad, NiMH, and Li-Ion batteries.

Lithium-ion Battery

Although lithium-ion batteries (Li-Ion) generally require the biggest financial investment of power tool batteries, they also outperform in many areas, like:

  • High energy density that helps it last longer and makes charging more convenient
  • Low-maintenance, lightweight and long-lasting designs
  • Specific safety features that prevent overheating

Nickel Cadmium Battery

Nickel-cadmium batteries are the oldest option available and are still in use today due to their long cycle life and durable construction. NiCad batteries are less susceptible to damage caused by heat and impact. They are relatively heavy and deliver lower torque capacity than other batteries.

Nickel Metal Hydride Battery

A nickel metal hydride battery, or NiMH battery, is made from newer technologies and has environmental benefits. They are less hazardous to the environment, can be recharged for years without losing function, and can last much longer nickel-cadmium batteries.

Are Replacement Batteries for Power Tools Interchangeable?

Some batteries for power tools are brand-specific. For example, an EGO 7.5 Ah battery is designed to be used with all EGO tools. However, it’s also true that many manufacturers make different types of cordless tools that can run off the same cordless tool batteries. Keep in mind that voltage differences are typically not interchangeable. You likely will not be able to use a 20V battery with a cordless 18V tool.

Refer to the instructions provided with your cordless power tool to determine its requirements. Consulting the owner’s manual is always the best way to learn about your power tools without risking damage to the tool itself.
