2009 Chevrolet Silverado 2500HD

The 2009 Chevrolet Silverado 2500HD is a heavy-duty pickup truck available with a 6.0L Vortec V8 gasoline engine or an optional 6.6L Duramax turbodiesel paired with an Allison 1000 transmission. The diesel 2500HD requires two batteries wired in parallel to provide the massive cold cranking amps needed to start the Duramax in cold weather — a setup that means both batteries must be replaced simultaneously and matched to the same specification. Oklahoma winters can expose a weak battery pair in the diesel 2500HD very quickly. OKC Mobile Auto provides mobile battery replacement for customers across the Oklahoma City area.

Not certain the battery is actually the problem? A slow crank or no-start on the 2009 Chevrolet Silverado 2500HD can also point to the alternator, the starter or a parasitic draw.
