The 2008 Ford F-350 uses a BCI Group 31S battery — Absorbent Glass Mat chemistry recommended. The Raya Energy catalog has 1 matching ZITEX SKU.
How many CCA does a 2008 Ford F-350 need?
OEM specifies at least 850 CCA (cold cranking amps). In Canadian winters, anywhere from 850 to 1020 CCA is sensible — higher CCA gives more starting headroom on the coldest mornings without affecting normal operation.
Does my 2008 Ford F-350 need AGM?
AGM batteries handle the deep-cycle demands and high-amp accessory loads modern vehicles place on the electrical system. Flooded chemistry will physically fit but won't last as long.
