Condemn the battery housing; check aircraft charging circuit. 6. Storage and Logistics Management

: Batteries are generally rejected if they fail to achieve at least 80% capacity (typically 48 minutes of discharge) after two charge/test cycles. Voltage Checks : ≥is greater than or equal to 25.5V : Battery is at 80%+ capacity and ready for service.

Evaluating the amp-hour capability to ensure the battery can meet the aircraft's emergency load requirements. 3.2. Maintenance and Servicing

Users must check for (the general index of technical manuals) quarterly to ensure they are not using a superseded revision.

: Minimizes the risks of thermal runaway, acid/alkali burns, and explosive gas generation. Key Battery Technologies Covered

The manual, often referred to as , outlines the procedures for operating specialized battery chargers (such as the 25-amp chargers commonly used). It is the definitive guide on ensuring that aircraft batteries are charged within strict voltage and current parameters. Key areas covered in the manual include:

Vented units and newer "ultra-low maintenance" variations.
