To provide professional-grade replacement batteries that deliver OEM performance at an affordable price, backed by industry-leading safety certifications and customer support.
Worthmah was established with a singular focus: developing high-quality replacement batteries for professional-grade cordless power tools. We recognized that contractors, DIY enthusiasts, and tradespeople needed affordable alternatives to OEM batteries without sacrificing performance or safety. Our engineering team focused on creating lithium-ion batteries that match or exceed original specifications while offering significant cost savings.
We specialize in replacement batteries for two of the most popular cordless tool platforms in the industry: Milwaukee M18 and Makita 18V systems. Each battery undergoes rigorous testing and carries multiple safety certifications including FCC, CE, RoHS, and UN38.3. Our commitment to quality has made us a trusted name among professionals who demand reliable power on the jobsite.
Today, Worthmah continues to expand our product lineup with various capacity options ranging from 3.0Ah for lightweight applications to 6.0Ah for extended runtime. Every battery features our integrated Battery Management System (BMS) and LED charge indicators, ensuring users always have the power they need when they need it.
At the core of Worthmah is Integrated Battery Management System (BMS) with multi-point protection circuit.
