i wanted to ask tho how much CCA do our trucks even need tho?
for example my vehicle has a gm 6.0 lq4 in it and its factory spec is 840cca.
840 seems very high and much higher then other trucks with bigger engines.
correct me if i am wrong but the battery is just for starting the vehicle and once the vehicle is on, the alternator should take over and the battery is essentially not be using correct? however once the vehicle is shut off then obviously the lights, radio, etc etc will run off the battery which would have to do with the reserve capacity. higher reserve capacity meaning more time to use those gadgets
i dont really have any extra mods or anything and nor do i ever listen to music etc when the truck is off. so do i really need 840 cca?
but also on a second hand it seems like 840cca is a good thing correct me if i am wrong because when it degrades etc it will be at about 700cca for example. i am just pulling numbers out of the air.
however if i compare that to a regular 750cca battery, then over the same amount of time in theory the degradation would bring it down to 650 cca.
lets say my truck needs in theory 675 cca to start minimum, and then in this scenario the 840cca would still be able to crank my truck until a certain date while the smaller battery would have already degraded to the point where it cannot start the truck anymore
i do live in alberta and it does get pretty cold here in the winters
so in this case, is it a good idea to get the bigger battery or am i wrong?
