Buying Guide for Best Battery for Cummins 6.7:

Types of battery:

Before making a purchase of battery for Cummins 6.7, look for the types of batteries. Primarily, there are 2 types of batteries for your diesel engine based vehicle in the market. They are AGM and lead-acid batteries. The AGM batteries are known to be sustainable options whereas the lead-acid batteries are the common options for diesel pickup trucks.

Cold-cranking amps:

The cold-cranking amps (CCA) indicate the total number of amperes the battery could discharge at a speed of 7.2A for 30 seconds at 0°. The extreme cold is one of the main reasons that lead to the difficult start of the engine. In case you live in a region where the temperature constantly drops below 0° F, look for a battery with a high CCAs rate. 

Reserve capacity:

With 25A of discharge, the run time of the overall battery is regarded as the Reserve capacity (RC). The corresponding measurement will usually influence the number of accessories you can operate by your truck before the battery dies. For that, the AGM battery is superb because of the highest RC. Generally, the AGM battery can retain nearly 80% of the charge after a significant discharge.


For your Cummins 6.7, make sure the battery you select has excellent reserve capacity, durability, and cold-crank amps. All these 3 batteries fulfill these aspects. They are useful for upgrading diesel engines in Cummins 6.7L.

From the discussion above, the winner is Delphi BU9094R MaxStart AGM Premium Automotive Battery. It provides excellent power delivery and a perfect fit for the vehicle. The heavy-duty power drives the engine of Cummins 6.7 perfectly.
