I am using the Odyssey PC 925 and also use a CTEC battery conditioner. I have this set continously on the winter setting, right through summer and winter. The reason for this was a piece I read about the PC 925 battery requiring a bigger continuous charge. I purchased my last battery from Demon Tweaks on the internet {about the same price as you have quoted} and it has performed well over 2 winters so far. In dry warmer weather my S1 starts immediately on the button, in colder damp weather the odd click before a start but always barks into life.
