Query: How many years do power tool batteries last?
Context: To sum it all up, the bare minimum that most manufacturers expect from their batteries is around 3 years or 1,000 charging cycles. With that said—we say “put your warranty where your mouth is.” Bosch, DeWalt, Metabo HPT, Makita, Milwaukee Tool, EGO, and Ridgid all warranty their Lithium-ion batteries for 2–3 years.
