The ‘R’ matters: Group 94R has REVERSED terminals compared to standard Group 94. Installing the wrong polarity means your cables won’t reach the terminals. Check your current battery — if positive is on the right when facing it, you need 94R.

Frequently Asked Questions

What battery does a Dodge Ram 1500 take?
Group size varies by year, engine, and trim — common sizes include 94R, 65, and H7. Always check the label on your existing battery, or call us with your VIN.

What does the ‘R’ mean in 94R?
R indicates reversed terminal polarity compared to the standard Group 94. Make sure your replacement matches your vehicle’s terminal layout.

Can I use 94R if my truck specifies H7?
Yes — H7 and 94R refer to the same physical battery dimensions and terminal layout under different naming systems (European vs North American).

Is 850 CCA enough for a Cummins diesel?
Diesel engines typically need 850-1000+ CCA. For Ram diesel trucks, confirm with us — you may need a higher CCA option or dual-battery configuration.
