I'm not always wanting to drive my 2003 Volkswagen Golf 30-odd miles once every two weeks during this time of year to keep my battery charged due to low usage. I have no electric available within my garage, which is 200 Metres from my flat. Am I able to piggy-back a fully charged, matching battery to my car battery via jump leads for, say, a month? Taking the battery off and charging at home means the ECU resets during the next drive (for 20 minutes) and is not advisable according to my local garage. To keep swapping batteries within a 2 minute period is achievable but a lot of bother. Thank you for your technical assistance on this subject.
