Understanding Power Tool Batteries
Find the best cordless tool battery for your needs. Learn the pros and cons of Li-ion vs NiCd and tips to make your batteries last longer.
A plumber should look at all the specialty tools available on a battery platform. It makes sense for the drill to use the same battery as the drain auger, crimping tool and bandsaw. Size, weight and portability are factors in choosing the best power tool batteries for your needs. Is your work primarily in a workshop or around the home?
I tested dozens of power tool batteries throughout 2025 and found eight brands that stand out in durability, efficiency, and overall lifespan. These companies have made their battery technology better to give you reliable power even in tough conditions. 1. DeWalt – Best for durability and jobsite use
Some brands offer budget-friendly options, while others are premium-priced. Ryobi, Craftsman, Ridgid, and Skil – Affordable tool/battery pricing, great for DIYers. DeWALT and Milwaukee (M18 Non-FUEL) – Good value for mid-range users. Makita, Bosch, and Milwaukee FUEL – High-quality tools, but batteries can be pricey.
Today, batteries can power most of the tools that used to require a power cord or compressed air line. Batteries also power many new tools and devices that didn't exist as corded tools. Drills, impact drivers and screw guns. Wrenches and ratchets for industrial, automotive and construction applications.
