Question about Auto batteries

Hi!

With all but the largest starters, I'd say that makes sense for unloaded operation.

I have a 1984 GMC pickup truck with the 6.2 diesel engine. Underhood are two

1000CA/900CCA batteries. On a cold day, without any help from the block heater, it is sometimes almost all those batteries can do to get the thing started. I cringe to think about the amount of current feeding that starter motor...probably nowhere near 900 amps, but pretty impressive nonetheless I am sure.

Fortunately, it has a block heater, which makes starting it in the winter as easy as the summer. Now if only it didn't put such a big dent in the electrical bill!

It also means that the battery cables will be a lot smaller. After all, that was their reason to go to a higher voltage electrical system.
