Aircraft Battery Capacity Testing, Inspection & Service Limits
Explore the named components, make a prediction, then connect the supplied result to the system. This workshop adds coached practice alongside the course handbook and assessed lab.
Concorde RG battery capacity and repeat checks
Explore how stored charge becomes a qualified capacity result and a traceable next-check record. Predict the relationship, reveal the supplied evidence and explain its scope. This optional practice preserves the existing BAT-100 lab, independent review, final and completion requirements.
Battery-test and evidence relationships. The power arrow represents the closed bench supply/return circuit; information arrows represent recorded observations, and workflow arrows connect method, interpretation and scheduling. This is not a physical wiring or servicing diagram.
Green outlines identify components named in the selected exercise record; they do not indicate a healthy component.
Named connections and what each arrow means
- Concorde RG battery and terminal voltage → Battery analyzer and controlled discharge loadElectrical power: Bench discharge supply and return circuit
- Concorde RG capacity-test conditions → Battery analyzer and controlled discharge loadTask sequence: Selected method and qualified preparation
- Battery analyzer and controlled discharge load → Discharge current, end-point voltage and elapsed timeInformation / signal: Actual current, endpoint and time observations
- Discharge current, end-point voltage and elapsed time → Measured capacity and post-test rechargeTask sequence: Valid record, calculation and capacity comparison
- Concorde RG capacity-test conditions → Capacity-test interval and test historyTask sequence: Application, utilization and governing schedule
- Measured capacity and post-test recharge → Capacity-test interval and test historyTask sequence: Capacity band and retained conditioning history
Concorde RG battery and terminal voltage
Stores chemical energy and supplies current to a complete external circuit.
How it works with the rest
A terminal-voltage reading identifies a potential difference under its stated conditions. A rested open-circuit voltage has no charging or discharge current; a reading while connected to a charger is a different observation. Starting is a short demand. Capacity is sustained delivered charge under a specified test, expressed in ampere-hours (Ah).
What the evidence must show
Keep charge state, a successful start, sustained capacity and installed supply/return performance separate. Equal terminal voltages do not establish equal capacity.
Selected: Concorde RG battery and terminal voltage
Follow the change through the system.
Fictional records A and B are two separate Concorde RG training batteries, each rated 40 Ah and nominal 24 V. Both have the same measured rested open-circuit voltage. Their qualified capacity records have not yet been revealed. For the later records, inspection and equipment checks, full-charge preparation and 25°C battery temperature are confirmed; actual discharge is 40 A C1 to the selected 20.0 V endpoint. This exercise selects the Rev Q 85% capacity minimum with no differing aircraft/equipment requirement.
Before the recorded change
Battery A and Battery B: the same rested terminal voltage, 25.6 V. Capacity-test elapsed times are hidden. Equal charge-state observations have not supplied delivered-Ah evidence.
Next observation
Choose your prediction before revealing the supplied result.

Course applicability and study references
Supplement to accepted BAT-100 Rev B. The numerical exercises explicitly select Concorde RG sealed lead-acid examples from 5-0171 Revision Q, December 4, 2018, ATA 24-30-71. They are fictional records, not instructions to discharge, charge or recover a real battery. Match actual chemistry, battery model, aircraft/equipment precedence, current instructions and any applicable fleet schedule before physical work. These RG limits and repeat recommendations are not transferred to nickel-cadmium or other batteries. No actual-aircraft endurance or maintenance release is established.
- Concorde RG definitions and selected capacity method
Concorde Battery Corporation, 5-0171 Revision Q, December 4, 2018, ATA 24-30-71: Introduction p.1 defines C1, capacity and open-circuit voltage; Testing p.106 gives actual rate, endpoint precedence, elapsed-time capacity comparison and post-test recharge. The examples here explicitly select that method and criterion.
- Application, utilization and conditioning history
Testing p.101 distinguishes main-turbine-start versus other uses and calendar versus aircraft-hour branches; its notes identify these as general recommendations subject to specific aircraft/fleet adjustments. Conditioning p.107 note 2 retains increased frequency after conditioning was required to pass. Initial and subsequent checks are distinct.
- Accepted BAT-100 Rev B teaching and practice
Ten lessons and the six-component explorer connect supply/return, charging, voltage, charge state and sustained capacity. Existing three fixed bench records, independent review and native final remain required. The new records A–D are original formative exercises with their own visible conditions.
Original learning diagrams and supplied training records explain the stated relationships. Current aircraft-effective instructions and authorization govern actual maintenance.
