What size battery ?

The accessories should not have any affect on how it starts. Only on the load the alternator has to put out to keep up...

(Wow, I said "keep up" and "put out" in the same sentence and didn't refer to a Kardashian...) LOL!


The purpose of the battery is to store charge to start the car. The alternator takes over once the engine is running and supplies all the power to run the engine and accessories and put the charge back into the battery that was used to start it.

Yea, I realize all that.
If you have electric cooling that is fully automatic like mine and it's hot out the fan runs for some time.
Then there's the parked and running the stereo and such.
The alternator isn't going to do you one bit of good unless you have the battery reserve to start the car. :-D

It's just some things I take into account when getting a battery.
