Battery and Alternator

[CSLC]

So I am pretty sure I have to install a new battery and alternator or maybe just a new battery with the dual set up....I have a red top with 800CCA. It is about 3yrs old. I just had a plow put on this year and have led strobes. What do you guys think I should go with for a alternator and/or 2nd battery....I am thinking leave truck hooked up to red top and new battery run plow or should I go vice versa?

So AAA just left my house....because truck was locked and dead battery...So with no juice truck would not unlock!!!! So AAA did a electrical system test and this is what they came up with:

BATTERY TEST

Voltage on Arrival: 4.04V
Cause of no start: Unknown
Battery Age: 3yrs Last started 1 day ago

BATTERY RESULTS, GOOD=RECHARGE

Voltage: 11.57V
Measured: 320CCA
Rated: 800CCA
Temp: 39F

He said, that my battery, alternator and charging system is all good. I am thinking it is the typical need second battery and or higher alternator and def thicker gauge wire....

Any insight would be great

Ck to see if you have a drain on your battery with the truck off. It's called a paracidic draw test. It'll tell you how many amps are being used while truck is off
