Hi again, ok I drive max 10miles per day 5miles to 1 destination stop, then 1mile to another stop, then another 4 to another destination fin. I have not done the maths and am crap at them , so could anyone tell me if driving on average 10miles per day plus the odd 50miles journey once a month would be enough to keep a standard x5 batt in good order? Got a bosh silver plus 120ah one instead of the standard 90ah…and alas got sluggish start issues a year after installing it(same symptoms as 9 year old OEM).
Suffice to say voltage readings are 14.3 when running engine and having lights etc its stays at 14.3v
12.38v when battery stone cold and car is not started.
I know CCA is crucial for startup which we haven’t tested, but could my driving style be the issue? Or batt not holding charge or starter being faulty and drawing too much charge on turn of the ignition? Or a parasitic power drain….?or all the above?
