Morning , Im going up North for Christmas and really don't want to brake down due to a bad battery (children and wife will never forgive me and I'll never forgive myself ), I hardly ever use the Land Rover , however it seems as though whenever I do any electrics and mess about with the lights that it drains the battery , Im getting a back up just in case , I don't want to spend more than £75 , any suggestions , I'll need to collect if for Christmas and am in Birmingham , I just don't think current battery should die do frequency.
