My GMC truck doesn's warm me when I turn the engine off and forget to remove the key. By morning the battery is completely drained. At -11 I was worried the battery may have frozen. I removed the caps and it wasn't.
I realize car batteries are rated in CCA. It got me to thinking, why don't they also have amp hour ratings too? That way I could calculate how long it will take to fully charge battery.
My charger is putting out 12 amps. At that rate, it will take many hours, like 24, before it shuts off. Looks like I'll be staying inside for a while.
The last time I had a stupid moment, I let the battery charge for 6 hours and drove to town. I could smell the alternator. I drove very slowly. It's a wonder I didn't toast the alternator. So today, I'll wait. Hope nothing comes up where I have to go to town.
