Battery light on but battery fully charged - 2005 Kia Sportage

Hi,normaly the green light says that the battery is fully charged,so if its red it might be that its charging but not fully charged,but saying that if it dose not charge after some time then the red light can mean its not charging,just food for thought,all the best.

Battery light on is the charging system fault its not charging the battery the video are example of your problem

it looks like you have a fusible link burn or open circuit
with a test light find out witch circuit is missing.
the starter have direct current from battery and ignition current to starter solenoid. maybe the problem is ignition switch or wires
hope it helps

Your battery is definately suspect.Give it a good charge and check it again. If it drops like that when you turn on the lights replace it.A fully charged battery in good condition will read about 14.2V when fully charged. When you turn the key to start it will drop to about 11 and come back up when you turn the key off.

How do you know the battery is good, fully charged may not be the case if the battery has a failed internal post connection. Have the battery load tested at a shop or a parts store.

have your alternator tested, and check all your fuses

The problem is most likely the starter, but you should ensure that the battery is fully charged before proceeding. The battery doesn't need to be fully charged to run just about all the interior lights and the head lights, but attempting to crank the engine is a large current draw, and can drop voltage quickly on a partially discharged battery.

If the battery is fully charged, continue to checking the starter.

check the alt might not be charging the battery
