Evening Folks , got a query regarding by Discovery 2 car battery. Bought a YUASA around 1 year ago & if it’s not started at least once a fortnight and taken for a run it goes totally flat.

Now it is a fair size of battery and as it’s used only on weekends is this the cause for it going flat. Is there anything I can do to prevent this from happening time and time again.

I was advised to take it for a run , how long a run would be best for once a week ?

Having it idling stationary would that also charge the battery or not ? Merry Christmas When It Comes.
