 I used an Odyssey PC680 (16ah, 15.4 lbs) in my Lyc 360 with 10:1 pistons for
2 years, after using it during construction as well(B&C starter). I changed it
at the second annual, just to be safe. It always cranks the engine smartly,
including fuel injected hot starts, and has never needed trickle charging.
 
 I am still using the first battery in my 4-wheeler.
