how do you know the battery is charged? also it could be a loose battery wire. they need to be properly thighten so the energy could flow. if there are no lights theres no power coming from the battery.
Yes
That probably indicates that the battery is not fully charged.
Yes, the battery starts the engine, and as long as the battery is fully charged the engine will start. The battery will loose it's charge if the alternator is defective and not replenishing the charge of the battery but the alternator has nothing to do with starting the engine.
check your fuses could possibly be a fuseable link by the starter
Start with the basics. Is the battery fully charged? Are the battery post clean and tight. If you answer yes to both of these and the engine will not turn over and you hear nothing, suspect the starter, starter solenoid, or ignition switch is defective.
You should never drive a car around for long after jump starting a dead battery. This puts an enormous strain on the alternator. Alternators are designed to keep a good battery charged, not to charge a dead battery. You can easily burn out a diode in the alternator. Jump start the engine and drive it somewhere and connect a battery charger to the battery and charge it fully.
the battery level will indicate 100%
Battery stave means nothing at all. Battery state on the other hand means the state of charge of the battery. Is it fully charged or 75%- 50%- 25% charged, etc.
When it is charging the screen reads: Battery Charging. When it is fully charged it reads: Battery Charged.
That probably indicates that the battery is not fully charged.
Jumping a Fully Charged BatteryIF the connections [jumper cables] are connected properly, then nothing out of the ordinary happens. Connecting a jumper battery or power axillary power source only makes additional current available, if the starting circuit needs it. If the batteries are connected properly [in parallel] then this procedure increases the cranking Amps available and the voltage remains the same.
The battery will run down and he engine will stop. You will not be able to start the engine. The alternator keeps the battery fully charged.
Laptops that's battery is fully charged does not weigh any more or less than one that's battery is not fully charged. If there is a difference, it would be so small you would not be able to tell.
