Should the battery for Golf 7 be replaced with 60 or 70?

Golf 7's battery should be replaced with a 60AH one. The battery is a crucial component of a car and also a wearable part. As the number of charge and discharge cycles increases, the performance of the battery may decline, so it needs to be replaced regularly. Maintaining good car usage habits can extend the battery's lifespan. On December 10, 2013, FAW-Volkswagen officially launched the new Golf 7 in Guangzhou. The Golf 7 has a body length of 4255mm, a width of 1799mm, a height of 1451mm, front and rear wheel tracks of 1549mm and 1520mm respectively, and a wheelbase of 2637mm. In terms of body colors, the Golf 7 offers nine options: Monsoon Gray, Maya Red, Magnetic Violet, Coral Blue, Deep Black, Reflex Silver, Tahiti Gold, Pure White, and Tanggula White.

I just replaced the battery for my Golf 7, and I've been thinking about it for a long time. The original battery was 60Ah, but the mechanic said a 70Ah one would also work, as the size is almost the same and it fits. The key is your driving habits—if you often take short trips and love listening to music, upgrading to 70Ah with higher storage capacity will last longer and provide more power for cold starts in winter. However, note that it's a few kilograms heavier and costs about a hundred yuan more. I finally chose the 70Ah one mainly because the dashcam and air purifier I installed consume a lot of power. On the highway, the alternator charges quickly, so I'm not worried about battery drain.

Last month, I personally tested the battery replacement for the Golf 7 and had a long chat with the repair shop technician. The original factory-matched value is 60Ah, which is completely sufficient for daily commuting. However, if you've modified the lighting or frequently use the car's charger without starting the engine, it's recommended to upgrade to 70Ah. I compared the data, and the starting current for 70Ah is actually similar, but it offers an extra 10Ah capacity, which is more friendly to the start-stop function. Pay attention to the battery compartment size—my car fits a Varta 70A just right into the mounting bracket, but other brands might require precise measurements. Just ensure the cold cranking amps (CCA) value doesn't drop below the factory's 540A.

Battery replacement depends on actual needs. I've changed mine twice in five years with my Golf 7, and a 60Ah battery still starts reliably at -10°C in winter. But if you're in northern regions or frequently drive at night, 70Ah provides better insurance. The weight difference is negligible – I weighed them and it's only 2.5kg difference. Brand selection is crucial – choose lifetime warranty models from Bosch or Varta, as their slightly lower capacity still outperforms no-name brands. After replacement, remember to reset the window anti-pinch and start-stop systems, which takes just two minutes with the dealer's computer.

As an owner of an older Golf 7, my experience suggests prioritizing battery compartment dimensions. After lifting the rear seat base and measuring the space, the maximum capacity can accommodate a 70Ah battery with a length of 278mm. If yours is a high-spec model with start-stop functionality requiring an AGM battery, the 70Ah is essential—60Ah can't handle frequent starts. Price-wise, the 70A is about 150 more than the 60A, but its lifespan extends by two years. The Varta Silver I replaced tested at 750A cold cranking current at -20°C, exceeding factory specs. For those with audio modifications, directly opting for 70Ah avoids battery drain from listening to music with the engine off.
