- Read the part number: Look for an Audi/VW part number (often starting with “8K0,” “8R0,” or similar) or an OEM supplier code such as Varta, Exide, or Moll.
- Note the size designation: Identify markings like “H7,” “94R,” or an EN/DIN code to confirm the physical size standard.
- Record capacity: Check for “Ah” (amp‑hours) value, commonly 80–95 Ah on an OEM Q5 battery.
- Check CCA rating: Find the “CCA” or “EN” rating, which indicates cold‑starting performance (often 800+ CCA).
- Confirm chemistry: Look for “AGM,” “VRLA,” or “Absorbent Glass Mat” printed on the label; this differentiates AGM from conventional flooded batteries.
This list describes the steps and details you should note from your existing battery to match a replacement accurately.
Once you’ve documented these figures, selecting a replacement becomes a matter of finding an H7/94R AGM battery that matches or slightly exceeds the original Ah and CCA specifications.
