3M 520-01-17R01 Battery

3M 520-01-17R01 Battery is a blue BP-17IS nickel–cadmium power pack designed for 3M Breathe Easy Turbo and related PAPR systems. As the BP-17IS battery pack, it provides the intrinsic safety NiCd power source for 3M PAPR assemblies such as the Breathe Easy Turbo belt-mounted unit (520-17-00) and the 022-00-03R01 turbo setup, and is used with 3M Powerflow face-mounted PAPRs. The pack is sold by 3M as BP-17IS battery, blue color, 1 per case. The chemistry is nickel-cadmium (NiCd), and the battery is explicitly described as Intrinsically Safe in official documentation, meeting UL 913 safety requirements in the appropriate configurations. This ensures use in environments requiring hazardous-location compliance, where the PAPR is used to supply filtered air in potentially explosive atmospheres. The 520-01-17R01 designation identifies this specific blue NiCd battery pack within 3M’s PAPR ecosystem, and related product matrices show that BP-17IS is the designated battery for these Turbo and Powerflow/PAPR assemblies. Note that older 3M PAPR matrices and user instructions reference the BP-17IS battery as part of the Turbo PAPR, and compatibility relies on using the BP-17IS with 520-17-00 or 022-00-03R01 components and the appropriate charger, per 3M manuals.
