Will long term use of a battery with cca greater than what the oem specifies damage the electrical system because of exposure to the excessive amperage?
See full version: Battery cca that is greater than what the vehicle specs require
Will long term use of a battery with cca greater than what the oem specifies damage the electrical system because of exposure to the excessive amperage?
The CCA is Cold Cranking Amps, and a battery’s performance is always reduced as the temperature drops especially in winter, then starting with more is better.
The starter will not wear more or less due to the battery CCA but will wear through use. So if it does not start very easily then that will accelerate wear, however starters are well designed and more efficient than those of 30 or 40 years ago so that is not much of a concern. With the auto stop start systems now fitted, starters are designed for some 10000 starts annually, consider delivery drivers in traffic. here
CCA or cold-cranking amps merely is unmeasurable. However, we can estimate it, and the process for estimation may take a week for one battery. That is why the full CCA testing is very seldom done because of its tedious process. here
However, you should not confuse it with CA or cranking amps. Cranking amps are going on at a rate of 32 degrees F, while Cold-cranking amps have a scale of zero. [links]
Some stationary batteries that are also lead-acid batteries require to have their capacity tested by using the charge/discharge process. Failures in these battery types are usually permanent and irreversible. However, it can still be restored depending on some circumstances. [links]
There are load testers made explicitly for car batteries.They usually use a carbon-pile in simulating the start of a vehicle at room temperature and will draw the battery to a low 8 Volts.
Most battery manufacturers would say that once your battery has lost its cold-cranking capacity, it will start showing symptoms of battery failure. Manufacturers would say that their batteries are designed to work efficiently at 600 CCA. If the CCA fell below that number, your battery will start showing symptoms of failure.
In small batteries (Li-Ion, NiCad, etc) this capacity is measured in mAh (milli-ampere-hours) meaning "at the rated voltage load, how much current can be drawn out of the battery and for how long". more

To further add to that argument if you put a far larger battery in the car than 800CCA (as long as you can devise a way to fit it and it is a 12V battery) and as long as the current draw of your electrical system is not exceeding it's capacity you would enjoy far greater life and voltage stabilisation than with a smaller battery.
The LARGER the tank, the more the tank can hold, the more capacity and the longer it can run. here
Starter operation advice is usually along the lines of;
1. If it stalls and does not turn the motor, switch it off immediately. Check the battery terminals. Find and fix the problem.
2. If it turns the engine, never operate the starter for more than 15 seconds, then wait a whole minute for it to cool. here
sounds a familiar problem, I highly doubt your starter did not turn because it was stalled because if hat was the case every time you would turn the ignition to start position your lights would flicker and get dimmed and after some 40 times of doing so your battery would be much emptier and our lights would go down much more, I assume that was not the case.
A larger battery solves none of these problems in starter motors.
your starter motor has a fixed impedance when its turning and it's coils have a fixed ohmic resistance by default , so at say 12 volts it can only consume a fixed amount of current under load, so as long as you don't change the voltage nothing else changes, it is the same starter motor turning the same engine for which it was designed and having the same impedance/resistance.
880 CCA is a fairly high rating by comparison, but is probably in the ballpark for an 8 cylinder gas engine, and necessary to get a high compression diesel engine turning. CCA (Cold Cranking Amps) is specified at 0°F, and CA (Cranking Amps) at 32°F with the ratio between them approximately 1.25:1 (for wet cell batteries - AGM batteries are a different sort of beast). Available cranking current falls with temperature; operation in extreme climates is another reason why a higher CCA-rated battery may be preferred.
