This has been probably covered before I can't seem to find any links.
I replaced my 94r size battery's for d3400s.
Truck is 13 ram 2500 diesel.
My stock battery's are 105ah with 750 cca.
It seem the 3400s have less ah but more cca.
I still have just as much drop as I had before with the stocks with the new 3400s.
Only running a bc2k @ 1 ohm.
Alternator is the stock 190 amp until my singer 275 ships hopefully soon.
Is my alternator can be able to fix drop or would I need to add a third battery in the back? I drop to high 12s. Idle around a 14.3
