Engine/Transmission (1998.5 - 2002) Normal current draw by Intake heaters?

[Ramtuf1]

Just wondering if anyone knows what the normal current draw is on the batteries when the intake heaters are cycling before engine start. I either have weak batteries (only 1 year old) or perhaps a heater module that is drawing excessive current. Thanks

Yep, that is why they have those big, fat wires!

Thanks for the responses. Does anyone have a suggested battery set in mind to get good service? I checked on Optima batteries at the manufacturer and they said that the 2nd generation Ram which calls for the Group 27, doesn't cross reference to any of their batteries. Does anyone know what is a good battery or should I go back to OEM?
