Is it just me or does everyone else have a problem releasing power cable from battery box, as I already suffer from arthritis in my hands I find it very very difficult on plugging and unplugging terminal into the socket with space for only one arthritic hand and having to try and raise the sprung locking flap with your fingers and pulling the same time, ( and it's always pouring down ) boy if I had a swear box next to me every time.
