Can a bad battery hurt an alternator?
A “weak” battery can’t consume much of a charge either so it won’t be much of a load on the alternator. So, no, a weak battery won’t hurt your alternator.
How does the alternator charge the car battery?
The alternator will charge the car’s battery by providing it with electricity. The alternator, on the other hand, is driven by the engine in your car. As long as the engine is on, the alternator will keep on charging the battery. It is a give and take sort of relationship between the two.
Can an alternator charge a deep cycle battery?
If you have an inboard or I/O (inboard/outboard) engine, then you too are likely to have an alternator to charge your boat batteries. While an alternator is a good way to charge your boat batteries while on the water, there is a lot more to know about maintaining your marine batteries.
How does an alternator protect a lithium battery?
The alternator is then charging the lead-acid battery, and the lead-acid battery is charging the lithium battery through a battery-battery charger. This is a reasonably cheap solution that both current limits the alternator (B-B charger) and protects the alternator form a load dump (lead-acid battery).
What should the voltage of an alternator be?
Start your engine (up to 2000 RPM). Again taste the battery by running the engine in such away. If your battery is showing a reading in between 13 and 14 voltage that means your car alternator is fine. If you get a battery voltage less than this range, your alternator has some issues.

Can a bad alternator cause a battery to go dead?
Diodes should allow current to pass in only one direction, but a bad diode will keep the charging circuit open even when the engine in not running, allowing the battery to go dead. This often happens overnight. Even when the alternator is functional, if the wiring between it and the battery is damaged, it won’t keep the battery charged.
