  1. How Power Tool Batteries Work • Power tool batteries are the driving force behind cordless tools, supplying the energy needed to power drills, saws, and other equipment without the hassle of cords.

  2. Battery Technology • Most modern power tool batteries use lithium-ion (Li-ion) technology, which offers a lightweight design, long lifespan, and efficient energy delivery.

  3. How They Function • Inside each battery are electrochemical cells that store and discharge energy. The battery releases direct current (DC) electricity to the motor, powering the tool instantly.

  4. Key Specifications • Important features include voltage (which affects power output) and amp-hours (Ah) (which determine how long the battery can run).

  5. Comparison With Older Technologies • Compared to NiCd or NiMH, lithium-ion batteries charge faster, last longer, and don’t suffer from memory effects, making them ideal for professionals and DIY users.

  6. Conclusion • Understanding how power tool batteries function helps you choose the right type, extend their lifespan, and get the most out of your cordless tools.
