Application notes

The P91-2kLi is meant for distributed IT, network and AV racks where sending a technician to swap batteries is the real cost. LiFePO4 is rated by Xtreme for up to 15 years and handles warm closets better than lead acid. It is built for ride-through and controlled shutdown; choose the lead-acid P91 with external packs when long runtime matters more.

Manufacturer warranty: 6 years electronics, 6 years battery (USA and Canada); 2 years where ambient runs 40-50 °C (104-122 °F), as published.
