How long does it take for an 18v battery to charge
I have learned that when i get new batteries for my hobby cars you want to fully charge the battery to the recommended hrs, you want to charge the battery fully because it will improve how long your battery will last on one charge and how long the battery's life will be.
The camera battery takes approximately 2 hours to fully charge.
I assume you mean how long to charge the battery. You should never let the alternator charge a dead battery if possible. The alternator is designed to keep the battery charged but not to charge a dead battery. You put a strain on the alternator and it can cause a diode to burn out. Drive home and then put a battery charger on the battery to fully charge it.
2 hours
Indefinitely.
Depends on the condition of the battery. Most will hold a charge for at least 6 months if they are not connected to anything.
The camera battery typically takes around 2 to 4 hours to fully charge.
