Univair Service Memorandum No. 67 contains a chart of batteries approved for various models. It shows the Concorde CB-25 or Concorde RG-25 are approved for use in the 415-C. Does that mean it would be illegal to use a Concorde-35, even if it could fit? (One mechanic wants me to use a Concorde-35 if possible, and I don't want to trouble figuring out if it would fit, if that would not be a legal installation.) Thanks -
