AGM vs Flooded 12V Batteries comparison checklist
Factor	What to verify
Vehicle application	Exact year, engine, powertrain and equipment
Manufacturer requirement	These are different battery chemistries. Start-stop systems, charging strategy and battery management can require a particular type.
Purchase check	Match chemistry, BCI group, CCA, polarity and hold-down. Check whether the car requires battery registration; do not swap types on size alone.
