how fast does the alternator charge the battery?
TL;DR: The alternator charges the battery as fast as the battery will let it, or as fast as the alternator can, whichever is lower, at a constant voltage (usually 13.8v, or 14.2v). The terminal voltage going down to 13.1v suggests the battery is not charging, and may be discharging, unless the battery is very low.
Why does my battery discharge while charging? : r/GalaxyBook
It is assumed that when it is set to 100% or 85% when the battery protection is activated, it stops charging and only uses alternating current, but this is not the case. Upon completion of charging, my old Dell would turn off the battery charge indicator light and only use power through the charger, not touching the battery power.

Problem, Increased Battery Discharge, Help! | MINI Cooper Forum
Disconnect the battery completely and see if it holds its full charge overnight, if it does then its probably ok, Put a meter on the battery to see how much current is being taken, if its draining as quickly as you say its something quite demanding. Then you need to start removing fuses to see which circuit is draining it if its not obvious.

6 FAQs about [How much current does an old battery discharge quickly ]
What does discharge rate mean in a car battery?
It’s like the fuel tank of a car, showing how much “fuel” is left. Discharge Rate: Expressed as a fraction of the battery’s capacity (e.g., 0.5C, 1C, 2C), the discharge rate shows how quickly the battery is being used. A higher discharge rate means the battery is “running” faster, depleting its energy more quickly.
What is the difference between battery voltage and discharge rate?
Battery voltage is like the runner’s stamina. Discharge rate (C rate) is the running speed. At low C rates, the battery “jogs,” depleting its stamina gradually and providing steady energy for long durations. At high C rates, the battery “sprints,” delivering high power quickly but exhausting itself faster.
How does a high discharge rate affect a battery?
Discharge Rate: Higher discharge rates can cause the voltage to drop more quickly, leading to a steeper discharge curve. It’s like running faster and getting tired more quickly. Temperature: Operating temperature affects the battery’s internal resistance and reaction kinetics, influencing the discharge curve.
What is an example of a battery discharge rate?
For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps. The battery discharge rate is the amount of current that a battery can provide in a given time.
How do you calculate battery discharge rate?
The faster a battery can discharge, the higher its discharge rate. To calculate a battery’s discharge rate, simply divide the battery’s capacity (measured in amp-hours) by its discharge time (measured in hours). For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps.
How long does it take a 12V battery to discharge?
The discharge time depends on the load current. For example, a 12V battery with a 10A load would discharge in 10 hours if the battery is rated at 100Ah. What is the discharge current of a 100Ah battery? The discharge current is the rate at which current flows out of the battery.
