I will be leaving my car unused for weeks at a time next winter. I’ve seen ads for solar powered battery rechargers that plug into the cigarette lighter. Anybody have experience with these things? Do they really work?
Any other ideas, other than calling AAA or a neighbor all the time?
Before you go and spend the money on one of these make sure that your cig lighter socket is powered up when the key is turned off in the car. Many cars power up this socket only when the key is in the accessory or on position.
Solar chargers will keep a fully charged battery fully charged (or nearly so) assuming that the car is parked where there is a fair amount of sun.
