Mobility Scooter (Humphrey's End GL5)

I bought this scooter a couple of years ago, second hand. It was really useful for local trips. After last winter, it does not seem to take a charge. It possibly needs a new battery, but I really don’t know. I have now bought one that easily fits into my boot, so this is now surplus to requirements. It does come apart for transportation, but more complicated than these new scooters. Good condition, mirror, basket, 2 keys, detailed book, instructions etc. Please give a tel no with your request.
