New owner here, 2013 LP 560-4 Spyder. I've had the car four days and have driven it daily: freeway/city. It's a new battery, Oct 2020, and has been slow to crank over after parking. The battery gauge looks fine while driving. This morning it was totally dead. It came with a silver Lamborghini trickle charger, but I thought I'd only have to use it if not driving for a couple weeks at a time? Last night I did leave the top down all night. Could that have killed the battery? What are some best practices to make sure it starts up every morning? For example, leave it parked in N or 1? Is it OK to leave my phone charger plugged in? Thanks very much.
