Question: are metabo and hitachi batteries interchangeable?
Answer: In a nutshell, Metabo HPT is just a different name and nothing else. The tools are the same, the warranty is the same, the batteries are the same. Batteries like the Hitachi MultiVolt will work in Metabo HPT MultiVolt tools. Hitachi 18V batteries will work in Metabo HPT 18V tools and vice versa.
