3M 520-01-61 10-Unit Smart Battery Charging Station

The 3M 520-01-61 Smart Battery Charger, 10-Unit, is a multi-bay charging station that recharges up to ten 3M PAPR batteries at once, enabling centralized battery maintenance for workplaces using 3M PAPR systems. It completes a full discharge-to-charge cycle in approximately 8 hours and uses individual LEDs in each bay to indicate charge status, with the charger automatically switching to a maintenance/trickle rate once the battery is full to prevent overcharging. The unit supports charging batteries outside the PAPR unit, helping keep spare batteries ready for use and simplifying inventory management in busy environments. It also provides overcharge protection to help extend battery life, and is commonly used in settings that rely on reliable, ready-to-go respirator power for continuous operation.
