The 2021 Ram 1500 is typically fitted with a BCI Group 94R battery — Absorbent Glass Mat chemistry recommended. The Raya Energy catalog has 1 matching ZITEX SKU.
How many CCA does a 2021 Ram 1500 need?
OEM specifies at least 800 CCA (cold cranking amps). In Canadian winters, anywhere from 800 to 960 CCA is sensible — higher CCA gives more starting headroom on the coldest mornings without affecting normal operation.
Does my 2021 Ram 1500 need AGM?
Yes — engine variants with start-stop technology require AGM (or at minimum EFB) chemistry. 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.
