Battery with higher amperage than the alternator. Is it worth it?
I believe this applies to any car not just mine, so I post it here in the general division. Sorry if it is the wrong decision.

I was wondering if it is worth it to use a battery with more amperage than what the alternator is rated. Right now I'm using a 80Ah battery, simply because the previous one was like so and the car was happy with it, so lets use this as an example.
Not sure how the electricity charging goes with cars, so my question is, are the extra 10 amps from the battery wasted?
No electrical problems except a very little dimming in instrumental panel's light and the A/C ventilation losses very little air pressure at idle. That with the head unit working. I notice this if I concentrate.
My plans are to add a second horn and possibly replace the mechanical fan with electrical.
Any thoughts? And thank you in advance.
