Re: Electrical Worry...
It does sound like your battery is loosing charge.
This could be down to three things: 1# Old battery... 2# Poor Alternator... 3# Load on battery when parked.
1: if the battery is more than 5yrs old, this could be the cause. Place a multimeter on the battery terminals when the car is parked, and see what measurement you get.
2: With the engine running, measure the voltage at the battery terminal. Should be 13.5 at a minimum.
3: Look for the interior boot light (if you have one) remaining on...?
