Using the 12V 18AH Batteries in a car

[Racer26]

@Mr V: You seem to know a lot about my car. Are you an insight owner too, or are you just looking this stuff up? Most people barely know these cars exist.

I know my 12V starter works fairly well. I had an issue with my HV battery last year where it blew the 100A semiconductor fuse, resulting in the car starting on the 12V for a period of a few weeks while the parts came in. I was just saying I've only ever had the car start on the 12V once due to weather conditions and such. Perhaps you're correct though, maybe I should intentionally force it to start on the 12v once in a while, just to keep the 12v starter running nicely, albeit unrelated to my current battery problems.

My father actually runs a repair shop, so he does the routine maintenance and most repairs. I live about 1hr from my workplace, so I do about 1000km (~600mi)/week. I change the oil 8-9 times a year (about every 6000km, sometimes as much as 10000km). Honda specs 12,000km cycles in most of the continental US, and 6,000km cycles in "heavy-duty" climates, meaning lots of dust (like the deserts of the western states) or extreme hot, or "Canada"). Naturally, I find it reasonable to believe that if a 12,000km cycle is ok in Buffalo, NY (according to Honda's guidelines), that stretching it past 6000km in Southern Ontario won't hurt anything.
