Can an alternator charge multiple batteries?
A car alternator will be more than capable of charging two batteries. However you need to be more careful about connecting two batteries together if one is charged and the other is not.
Can a battery be shared with an alternator?
In order to share an alternator with more than one battery we need 1) a parallel battery switch, e.g. Off-1-2-both, 2) a battery combiner or 3) a battery isolator. Dedicated Battery Banks. Nowadays, separate battery banks, for different purposes, is the norm.
How long does it take to charge a battery from an alternator?
As long as the battery voltage rises when the engine is running, you know that your alternator is working. The ratio between the battery bank and the alternator will dictate how long it will take for the charging voltage to reach 14.4 volts.
How do I know if it’s the battery or the alternator?
Both of these car parts control your electrical system. However, your alternator charges your battery while your battery supplies power to your car. The failures of a battery are sudden, while failures of a failing alternator are slow. Always check your battery first, it can generally tell you which of these two is the culprit.
What happens if the alternator is not working?

What happens to a car battery when the alternator goes bad?
As batteries age, they become less able to retain a charge because the metal inside corrodes. Eventually, the level of battery charge diminishes to the point where, no matter how much power the alternator gives to it, the battery can’t hold enough power to start the car.
As long as the battery voltage rises when the engine is running, you know that your alternator is working. The ratio between the battery bank and the alternator will dictate how long it will take for the charging voltage to reach 14.4 volts.
What should I do if my alternator is not working?
Check if it’s properly supported by the hook rod or not. Start the engine. If your car is already having difficulties in starting the car it may take time to start it. If it starts, keep the engine running. Go back to the battery. Check if there is some dirt or corrosion around the battery’s terminal. Remove it if present.
