Because I use my scooters electric start and I only travel very short journeys, the battery seems to have a net drain and requires a topping up charge every couple of weeks. I have got round this by adding a solar panel onto the top box to trickle charge the battery. It works too. It was only £9.99 from Maplin and outputs 1.5 watts. It's already started to attract attention with a few people asking me what it's for.
