6 volt cranking amps

How are the 6 volt batteries rated are they in cold cranking amps?

What rating would a farmall 140 take?

Thanks in advance.

Nowadays I see CCA as a common or most prominent displayed rating on batteries. It may have the reserve capacity also. In years past Id see Amp Hours as the more common label. If you get into Amp Hours thats more of what I view as an "energy storage capacity" while CCA is more of how many amps can it pump into my starter for how long before the volatge drops to x volts. Its that initial short term high current you need to crank the engine esp when its coldddddddd so you need a regular starting NOT a marine deep cycle (longer slower gradual deeper draw) battery of course.

If youre most interested in getting her started and then allowing time for her to replenish (which is the design for starting batteries) LOOK AT CCA and the more the better

If youre more interested in a lower current deeper draw longer operation time (Marine trolling motor batteries) then look at Amp Hours (energy storage capacity)

REGARDLESS, OBVIOUSLY THE HIGHER EITHER NUMBER THE MORE BATTERY AND ENERGY STORAGE YOURE BUYING

NOTE for 6 volt applications I advise people to buy the biggest heaviest highest CCA rated battery that will physically fit in the space provided. If you have that and use 00 Gauge Battery and Ground and Starter Cables with a good solid heavy ground and have the engine well tuned and the staretr in good shape THEY OUGHT TO STILL START AT 6 VOLTS if you hold your mouth to the right that is

I will add that the 140 is the smallest (of the era) Farmall engines. Not really an issue of starting, but heavy cables are the best option. Above 500 CCA will be OK. Jim

thanks John, I know some of the smaller batteries still come rated in amp hours (for emergency lighting and things like that)
