- Group size (e.g., 24F for Honda Accord, 48H6 for Audi A4)
- CCA rating (varies by climate—650+ CCA for cold regions)
- Terminal configuration (top-post vs. side-post)
Example: A 2020 Ford F-150 requires a Group 65 battery with at least 750 CCA—AAA would pre-select an AGM option like the Interstate MTX-65 for trucks with plow packages.
Step 2: On-Site Diagnostics
The technician performs three critical tests before installation:
- Voltage check (healthy batteries show 12.4–12.7V when off)
- Load test (simulates cold-start demand at 50% charge)
- Alternator inspection (rules out charging system issues)
Pro Tip: If your battery tests “weak but functional,” AAA may recommend replacement anyway—a battery at 60% capacity in summer can fail completely in winter.
Step 3: Safe Replacement Protocol
Using memory savers to preserve ECU settings and terminal protectors to prevent short circuits, technicians:
- Disconnect negative cable first (reduces spark risk)
- Inspect tray/tie-downs for corrosion damage
- Apply anti-corrosion gel to new terminals
Real-world scenario: For European cars with sensitive electronics (e.g., BMW iDrive), AAA uses specialized 12V power supply units to avoid system resets during replacement.
Post-Installation Verification
Every installation includes:
- Charging system test (13.5–14.7V when running confirms proper alternator output)
- Battery registration (for BMW/Mercedes to reset adaptive charging profiles)
- Warranty activation (includes free replacement periods—typically 3 years for AGM)
Note: AAA’s mobile service can’t handle some luxury/exotic vehicles (e.g., Tesla, Porsche Taycan) due to high-voltage systems—they’ll refer you to a certified dealer instead.
