Many diesel truck owners do not understand battery specifications and how well the battery will perform when starting the engine in all types of weather. Owners are often unaware of the factors that affect the useful life of batteries. Here are a few FAQs to help you select the best battery for your diesel.
Basic Battery Specifications FAQs
What Does CCA Mean? CCA refers to Cold Cranking Amps. One of the specifications developed through standardized testing is the discharge load in amperes. A new and fully-charged battery can deliver for 30 seconds in a temperature of 0 degrees Fahrenheit and 18 degrees Celsius. The terminal voltage required during the 30 seconds is 1.20 volts or higher per cell.
Should I Buy a Battery Based on the CCA Rating? Probably not. Operating a diesel truck in a climate where CCA batteries would be beneficial is uncommon. If the batteries are well-maintained and inspected regularly, they should provide the cranking amps necessary to start the vehicle in any climate. Batteries should meet or exceed the diesel engine manufacturer's’ recommendation for cranking amps including cold cranking amps. Battery manufacturers have created the impression that “bigger is better.” At Bodacious Diesel, we can help you select the best battery for your requirements.
CA and MCA? Many batteries are sold with a CA rating, which refers to the cranking amps available to start the vehicle. MCA refers to Marine Cranking Amps. These ratings are determined by the same tests that are used for the CCA rating, except the tests are performed at 32 degrees Fahrenheit and 0 degrees Celsius.
What Has Caused the “Bigger is Better” Mentality? Battery manufacturers want to sell the bigger batteries, meaning they will praise the virtues of CCA batteries. Selling higher cranking amps means more profit. However, praising a battery because it has a high CCA number is misleading.
Are Other Battery Ratings Available? Some battery manufacturers have come up with their own rating schemes. This makes it impossible to compare these batteries across the range of manufacturers. CA and CCA ratings are a starting point for comparing batteries.
The Major Factors that Affect Diesel Truck Battery Life
Batteries are subjected to a higher load when the engine is started often and when the engine runs for a short period, especially when the weather is cold. Hot weather can also put a strain on the batteries. Summer heat will evaporate the water from the batteries, which if not replenished, will result in damage to the batteries. Battery life can be drastically shortened by an overcharging alternator, and corroded battery terminals can affect the life of the battery.
