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. Generally speaking, 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 with their 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. 

• high energy density that helps it last longer and makes charging more convenient
• low-maintenance, lightweight and long-lasting
• specific safety features that prevent overheating

Nickel Cadmium Battery 

The oldest type of the options available, nickel-cadmium batteries are still in use today thanks to their long cycle life and durable construction. 

• NiCad batteries are less susceptible to damage due to heat and impact
• Relatively heavy, they deliver lower torque capacity than other batteries

Nickel Metal Hydride Battery

A nickel metal hydride battery, or NiMH battery, are made from newer technologies and have environmental benefits, including: 

• less hazardous to the environment
• Can be recharged over a period of years without losing function
• Last two to three times longer than 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. But it is also true that many manufacturers make different types of cordless tools that can run off the same cordless tool batteries. However, voltage differences are typically not interchangeable. You likely will not be able to use a 20v battery with a cordless 18-volt tool.

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