[OBethany]

Audi A7's battery positive and negative terminals are located in the trunk at the rear of the vehicle. Remove the battery protective cover and electrode protective cover to see the "+" sign as the positive terminal, while the "-" sign indicates the negative terminal. 1. Battery lifespan: Currently, all car batteries are lead-acid batteries, typically lasting about two years. With careful and proper usage, they can last 3-5 years. 2. When to replace the battery: Generally, there is a battery warning light on the car's dashboard, which should turn off after the engine starts under normal circumstances. However, if the warning light remains on while the engine is running, it indicates that the battery needs to be checked or replaced. A more direct method is to open the engine hood and observe the battery. Most maintenance-free batteries have an inspection window: green indicates normal, black indicates charging, and white means the battery must be replaced.
