The RPB® 03-856 High Capacity Battery is a rechargeable lithium-ion battery designed for the RPB® PX5® Powered Air-Purifying Respirator (PAPR). Developed as the high-capacity battery option for the PX5®, it provides extended operating time compared with the standard battery, with minimum runtimes varying according to airflow speed and the filter or cartridge installed. The battery charges in less than 5 hours and is rated for more than 500 charge cycles while retaining greater than 80% of its original battery capacity. Depending on the PX5® configuration and operating speed, minimum runtime ranges from 6+ to 13+ hours under laboratory test conditions.
