Intermittent starting issue

Dear Ken,

Good Day,

Well, the Jaguar car is running in perfect condition, locking and unlocking as it should be and the engine starts immediately and I am very happy with it, no security issues anymore.

By the way, do you have any idea in Mercedes Benz, I actually own another car it is 2001 Mercedes Benz S600 W220, recently the a new Battery replaced but it gets drained quickly within one day, I have checked the alternator voltage it was 13.8, once I do jump for the battery the car runs immediately and next day the battery again drained.

So hope we can solve this issue too, thanks.
