This heavy-duty lithium-ion battery upgrade kit (part number 837631C) is designed for use with the 3M Adflo Powered Air Purifying Respirator (PAPR) system. It includes the upgraded lithium-ion battery and a rapid charger, providing enhanced performance and compatibility with Speedglas Adflo welding helmets and 3M Versaflo clear face shields.

The lithium-ion battery charges up to 80% capacity in approximately one hour, with a full charge achieved in 5.5 hours. Compared to the older nickel-metal hydride (Ni-MH) battery, this upgraded battery is 40% lighter, reducing the overall system weight by 15% and helping to minimize operator fatigue during extended welding sessions.

At a flow rate of 170 litres per minute, the battery delivers approximately 12 hours of continuous running time, assuming use without gas or odour filters and with clean pre-filters and particle filters. The rapid charge function supports efficient workflow by minimizing downtime, allowing welders to recharge quickly between tasks.
