Handbook says 720 cca. My battery is only 520 cca.

 

Rogelio, the 520 amp battery will start the car. But, it may not have a long life. You are stressing it each time you start the car. I am an avid believer in fitting the biggest battery you can into a vehicle. This benefits you 2 ways. The big one being that when you are having issues starting the car, you have that much more time to get it started. The second being that your battery performs a vital job when the engine is running. That would be to filter out alternator noise. A smaller battery will not do as good of a job as a larger one. More noise stresses electronic components more, leading to more failures and an increased likelihood that you are going to get random error codes with no real reason for them to occur.

 

Jaguar recommends H7 battery for your car.

What would be the equivalent in the U.K.? I found a type 096 on eBay. Supposed to fit the tray. 80ah 780 cca.

 

Never heard of buying a car battery on eBay. Would never do it either.
