Bigger Doesn't Always Mean Better
With the cold weather months upon us, starting up trucks can be a concern. Having the right size of battery is vital to supplying the necessary cold cranking amps (CCA). And bigger doesn't necessarily mean better.
"It's not uncommon for someone to select a battery above the recommended battery size," explains Marcos Naby, a field trainer in Tech Support. "People often think a larger size battery will provide them with even more power to crank up their truck."
But that could be a mistake.
Going up too high in battery CCAs could potentially cause damage. Too much power could place excessive heat in the solenoid - and cause even bigger problems with the starter.
Below are the maximum battery sizes and quantities we recommend. If you have questions, call the Delco Remy Technical Support Center at 1-800-372-0222 for assistance.
