I love you Carmen !
It don't matter eather way.
No, these types of batteries are not technically able to be recharged.
try charging your battery or maybe you completely turned off your ipad
When the ignition is turned on, battery voltage passes down the wire to the alternator to 'excite' the alternator when the engine starts. When the engine starts and the alternator generates a voltage, the light is extinguised by the charging voltage cancelling out the battery voltage coming down the wire. If and when the alternator completetly fails the the light will come back on as there is no sancelling voltage. if the alternator produces a voltage lower than the voltage from the ignition switch then the battery light will glow.
As long as the headlight are turned off, you do not have to disconnect the battery.
It will not unless you start it on a charger, then insert the battery after you've turned it on, then remove the power cord.
This should not damage the laptop at all, they are designed to be turned on at any time. (Unless of course the battery is dead.)
no
all vehicles will drop a certain amount of voltage when accessories are turned on, you need to determine how much voltage is being drawn by using a volt meter, also check charging system and battery condition, if battery is weak or charging system isn't providing enough voltage back to the battery, that can cause your problem and last but not least make sure your battery cables and battery posts are cleanThe battery's charge is low or something is drawing from it.
alternator is bad........ my best guess.... or your battery is surface charging and cant take a load....... go to an autoparts store like advance or autozone n have them check the charging system and battery. -Jarrid-
Automotive Battery VoltagesAssuming your voltage meter is accurate, the battery is fully charged, when the key is turned on, without the engine running, and no accessories turned on, the meter indicated voltage should be 12 volts. When the engine is running and the alternator is charging the battery, the voltage should indicate anywhere between 13 volts to about 14.6 volts.Answer 2 - A wider Acceptable Range13.5 −16 volts is acceptable with the engine running.
Your vehicle has a 12 volt system, charging should be approx. 14 volts with engine running. Acceptable range is 12.5-14.5 volts. If charging is above 15 volts (assuming you have a fully charged battery) you might have a bad regulator. A faulty regulator will discharge you battery when the engine is turned off.
