All.....
I consider the PC680 has a particular capability of being able to give up
its power very quickly in the start process when compared with competition.
I originally had a Jabiru 3300 which needed a very high cranking capability
with the six pots coming onto the compression stroke in quick succession.
Much larger batteries proved incapable to give out the start power quickly
enough, so I finished up with two p680 type( sometimes known as "RED TOP"
).in parallel. When I changed engines to a 914 Rotax I kept the two
batteries employed even though I have a heavy duty rotax starter. Keeping
the two helps with redundancy issues too.
I suffered exhaustive times starting the 6 cylinder engine and tried even
heavy construction batteries with no success. All started in 1999 and I am
now on my second pair nearly twenty years later! Having used both the
originals on emergency car and lawn mower duties since recovery from the
aircraft.

Reading the spec's of the PC680 then the PC625 I was left questioning why
the popularity of the PC680? It has lower power than the PC625 by 10 to 20%
in all spec's. It's also 1 kilo heavier. Maybe the shape is the reason? I
asked the Odyssey rep why the better spec's on the PC 625 his reply "The
PC625 is a more efficient design"
