Hi All - thinking about trying a solar charger to top up the car battery’s on the Z4 and TT - have 3 cars and between me and the wife try and run them all regularly but inevitably one ends up sitting on the drive for longer than it should or used for shorter journeys usually the Zed or the TT - haven’t got a garage that’s accessible so been thinking about a Halfords solar charger to keep the car not being used topped up - anyone one got any experience of using a solar charger are they any good ? any potential issues - many thanks G
