In the 2020 Audi Q5, the standard gasoline model uses a 12-volt battery, while the plug-in hybrid variant carries a high-voltage battery around 14 kWh of usable capacity. In other words, you’ll find a traditional 12V battery on most Q5s and a separate ~14 kWh lithium‑ion pack on the Q5 55 TFSI e.
Standard Q5 (gasoline): 12V battery basics
The typical 2020 Q5 with a conventional gasoline engine relies on a 12-volt battery to power starters and electronics. In modern Audis, this is usually an AGM (absorbed glass mat) lead‑acid battery, rated around 70–80 ampere-hours (Ah). Exact size and whether it uses an AGM or a standard lead‑acid can vary by market and trim, so check the battery label for the precise specification.
Here are the common characteristics you’ll see in this variant:
- Type: 12-volt lead-acid battery, commonly AGM in newer Audi models
- Capacity: typically about 70–80 Ah (roughly 0.8 kWh of stored energy at 12 V)
- Role: powers engine starting, lighting, infotainment, and the stop/start system
In short: for the non-hybrid Q5, you’re looking at a standard 12V battery, with size varying by market but generally within this range.
Plug-in hybrid Q5 55 TFSI e: high-voltage battery
The plug-in hybrid variant uses a separate high-voltage battery pack to enable electric driving. For the 2020 Q5 55 TFSI e, the usable capacity is around 14.1 kWh, with a larger gross capacity listed by Audi in some markets. This battery allows a portion of daily trips to be completed in all-electric mode, before the petrol engine assists as needed. The 12V battery still powers low‑voltage systems, but the high-voltage pack is managed by the hybrid system.
Key details about the high-voltage pack include:
- Battery type: lithium‑ion, high‑voltage pack
- Usable capacity: about 14.1 kWh (net usable) for electric driving
- Purpose: provides electric range and supports hybrid operation alongside the gasoline engine
In summary, the 2020 Audi Q5 line-up uses two different battery sizes depending on configuration: a 12V lead‑acid/AGM battery for standard models and a roughly 14 kWh high-voltage lithium‑ion battery for the plug‑in hybrid.
Additional context and care tips
Regardless of variant, battery health matters for reliability. Regular checks, proper charging, and replacement by authorized service are recommended. If you’re unsure which battery your Q5 has, consult the owner’s manual or your dealer for the exact specifications for your VIN.
Summary: The 2020 Audi Q5 features a standard 12V battery (roughly 70–80 Ah) for gasoline variants and a ~14.1 kWh high-voltage battery for the Q5 55 TFSI e plug‑in hybrid, with the 12V system still present for low‑voltage needs.
