3. Select a battery for your GMC Sierra 2500 based on our review

Key criteria for choosing a battery for your GMC Sierra 2500:

• Capacity. For diesel cars and SUVs with a large engine capacity, we recommend using batteries with a capacity of 70-90 Ah. Stick to the GMC Sierra 2500 manufacturer’s recommendations and use a battery with the rated capacity for the GMC Sierra 2500.
• Starting current. The maximum amount of current a battery can deliver in a short period of time (10 to 30 seconds). Cold Cranking Amps (CCA) – The cold cranking current of a starter battery. For GMC Sierra 2500, it is recommended to use a battery with CCA between 700 and 800 A. We recommend choosing a battery for the GMC Sierra 2500 with higher starting current ratings. Such batteries are more expensive, but they allow you to start the engine GMC Sierra 2500 even in severe frost.
• Dimensions. Pay attention to the size of the battery pad in your GMC Sierra 2500.
