LiFePO4 UPS Battery Test Outperforms Expectations


On November 23rd, 2016, Battery Backup Power, Inc. completed initial testing of its LiFePO4 (Lithium Iron Phosphate) UPS battery. The battery is designed to be a drop in replacement for standard sealed lead acid batteries. It consists of an internal battery management system board and lithium iron phosphate cells enclosed in standard UPS battery form factor for plug and play use.

During initial testing, the LiFePO4 batteries charged faster and lasted twice as long the standard 12 Volt 7.2 Amp Hour sealed lead acid batteries normally included with the UPS model used during the test (1000 VA / 700 Watt Battery Backup Uninterruptible Power Supply (UPS) And 4 Tier Active Power Conditioner).

Additional testing will continue throughout the end of the year with shipments scheduled for January 1st, 2017. Pre-orders are being filled by email ( and phone (855-330-7799) as the battery is not available for purchase on the Battery Backup Power, Inc. website currently.
