Linda. The 35 amp batteries fit the battery tray perfectly. It seems that the original 24 amp batteries used to be bigger, but lighter. The 24 amp battery is smaller and one needs to add some spacers around them, but they are sufficient for the job and less weight. They are also cheaper. I went with the 24 amp battery recently and feel good about the lesser 9 pounds in the back. If your mechanic wants to go with the 35 amp battery , it is understandable , because they fit the tray perfectly. But just show him the Memorandum and ask him why he insists on installing a battery he needs to gain a field approval for.
Hartmut From: Linda Abrams Sent: Monday, June 14, 2010 8:34 PM To: [email protected] Subject: [ercoupe-tech] batteries 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 - Linda N3437H (Sky Sprite) L.A.
