CTEK 7002 Trickle Charge
Anyone use the CTEK 7002 charger for an extended period of time? My 2011 M3 has to sit in the garage for about a month (unattended) and I was going to hook up the CTEK to the battery terminals in the engine bay. I have not done this before for an extended period. Is it completely safe? Thanks.
