What is the ampere rating of the Audi Q5 battery?
3 Answers
Some Q5 models use start-stop batteries with 80 ampere-hours, while others use 105 ampere-hours. Frequent charging: Car batteries need to be charged regularly. If left unused for a long time, the battery will gradually self-discharge until it becomes unusable. Therefore, the car should be started periodically to recharge the battery. Regular cleaning: Clean the battery terminals periodically and apply specialized grease to protect the wiring harness. Regularly inspect the battery components and connecting circuits. Avoid using electrical appliances after turning off the engine: Using car electrical appliances after the engine is turned off is prohibited. Running the battery alone without the engine generating power can cause damage to it.
I've been driving an Audi Q5 for five years. The original battery was labeled 80Ah, and I later replaced it with an 85Ah one, which has been working steadily. After checking the manual, I learned that different model years have different specifications—for example, some high-end models after 2018 use 90Ah batteries. When replacing the battery, it's crucial to match the Ah rating; a lower one can make winter starts difficult. I recommend checking your car's manual or the label on the old battery—those numbers are far more accurate than online searches. For cars with auto start-stop, make sure to choose a battery that supports this feature, as a regular battery might fail within six months.
In the repair shop, we often encounter Audi Q5 battery replacements, with the original factory battery typically being 80Ah. Actually, the ampere-hour rating is just a basic parameter; the cold cranking amps (CCA) value is more critical, especially in northern winters where temperatures drop below minus ten degrees Celsius. If the CCA is below 700, the car might not start. When replacing the battery, it's essential to first test the alternator's charging voltage—if it's too high, it can shorten the battery's lifespan. The battery box location in the trunk is a bit awkward, requiring about half an hour for removal and installation. We recommend using EFB or AGM batteries; although they cost about 200 yuan more, they can reliably last two extra years.
