Schedule to be agreed to by Government and Contractor prior to contract award.

Required Tasks: Visual cell checks for leaks, swelling, or corrosion;

logging of cell voltage, internal resistance/conductance, and ambient temperature; terminal cleaning and retorquing; and a cumulative health trend analysis to identify failing jars.

2.2 Scheduled Lifecycle Component Replacement - The Contractor shall perform full battery string and capacitor assembly replacements based on the schedule in Section 4.2.

Parts Standard: All parts must be new, unused OEM-standard components.

2.4 Beyond Economic Repair (BER) Threshold - A unit is considered BER if critical parts are permanently unavailable, or if the estimated repair cost exceeds 65% of its current market replacement value. Upon determining a unit is BER, the Contractor shall immediately halt repair efforts and notify the COR.

2.5 Service Reports - The Contractor shall submit a detailed written service report to the COR within five (5) business days of any PM or on-demand maintenance and repair visit. Battery maintenance reports must include tabular raw data and trend graphs for individual cell voltage and impedance / conductance.

3.0 Quality Assurance Surveillance Plan (QASP) - The Government will monitor Contractor performance using the following surveillance metrics:
