Hi Linda,
I agree with Hartmut. Why would anyone haul around 9 pounds of useless
weight they don't have to. The 24 amp battery has always been standard
in the Forneys, Alons and M10s with the 90 hp engine, which has higher
compression, and therefore has more resistance when cranking. To my
knowledge there has never been a "battery wall failure" in recent years
of those installations.
Regards,
WRB

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.

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 -
