Low battery symptoms

You can prove this to yourself by simply running a voltage drop test on the cables; anything more than 0.5 volt drop and the cables need to be replaced.

Yes and when he says the "restart is slow" with engine warm.
Does he mean the starter spins the engine over slower when warm then it does when the engine is cold???? Which would be caused by the voltage drop situation you describe.
Or does he mean the starter spins the engine over for a longer period of time before it starts when warm versus cold.???? Which often times is caused by an issue with the EVAP. system. Things like the purge valve being stuck open.

Easy enough to find out: Run a voltage drop test………

Update: picked up a new Delco battery yesterday. 780 CCA, fits nicely, starts like a champ.

$228 CAN with a 30 month warranty included.

I changed the battery in the parking lot and they even took my old one for free.

One less project!
