Bragg Battery String 3 Report.pdf

This is a battery system monitoring report documenting the condition of UPS 3 (Uninterruptible Power Supply), a 16HX800 model unit installed at Fort Bragg on March 3, 2026. The report presents cell-level diagnostic data collected on February 26, 2003, and was generated on March 6, 2026.

The report contains readings for 30 cells within String 3 of the battery system, measuring three key parameters: cell voltage, internal resistance, and intercell resistance. Overall voltage measured 518.9V. Cell voltages ranged from a high of 17.354V (Cell 3) to a low of 17.200V (Cell 30), with an average of 17.297V across all cells. Internal resistance ranged from 2,976 to 3,318 micro-ohms, averaging 3,151 micro-ohms. Intercell resistance values ranged from 937 to 1,274 ohms, with an average of 1,225 ohms. The data is presented in tabular format with accompanying bar charts visualizing voltage consistency, internal resistance distribution, and intercell resistance variation across the 30 cells, providing a comprehensive baseline assessment of the battery string's operational health and uniformity.
