I have a Concorde CB-35 (CB-35A?) but when it's day is done, it will be a Concorde RG-35A that goes in. My CB-35 has been really fine - you want to cough $150 for the aviation BatteryMinder which will markedly extend your battery life, and assure of a snappy start every time. My BatteryMinder is giving every indication of providing a year or two more life out of my CB-35 (my first airplane battery).
