Batteries and CCA Ratings

[Gilbey]

Hey yo quadsters, I have a question regarding CCA in batteries. My ATV is cold natured and it will start with my generic battery that's in it, (don't ask me now what battery I have in it cuz I'm at work,) but when I hook up an external battery storage unit (Beatit 1200Amps QDSP 1200A Peak 16500mAh 12V Portable Car Lithium Jump Starter) for quick jumps it fires so much faster.  Which by the way is a bad as* accessory to have around. I keep the battery in the quad fully charged all the time. My question to the pros is how much difference does the CCA of a battery contribute to the quicker start?

Great question. CCA stands for Cold Cranking Amps. The higher that rating, the more power you will notice cranking. Here's a good resource:

Generally speaking, it is easier to start an engine in a warm environment than in a cold one. The rating refers to the number of amps a 12-volt battery can deliver at 0°F for 30 seconds while maintaining a voltage of at least 7.2 volts. The higher the CCA rating, the greater the starting power of the battery.

The  lithium  battery  in that jump starter also  delivers  a  higher  voltage  and amps  than the lead acid  one in the  quad . It  is that higher voltage under load  that spins the  quad over  faster .  The  CCA  rating does make a difference   when  it  is really  cold .  No  matter  what the  CCA  rating is ,  it  is an adventure  starting a vehicle when the  thermometer is frozen  at  40  below.

A battery  that  matches the  OEM  rating for the  machine should start  the  quad  reasonably  fast  down  to  about 0 Fahrenheit  but after that  one with a  higher  CCA  rating will make a bit  of  difference .
