b.There is problem with charger, as it has no output electric current.
c.Low charging efficiency due to external cause.
2)Solutions:
a.Test whether the charger has voltage and output electric current or not.
b.Check if the charger is well contacted with battery.
c.Activate the dell inspiron 1545 batterybattery with voltage and current 1.5 time higher then the highest ones of battery. (Use this method only when the battery can't be charged.)
What's the reason that causes the dell inspiron 1545 with no voltage or low voltage? How to avoid this problem?
1)Reason:
a.No voltage.
b.External shot circuit or overcharge, anti-charge
c.Cells expansion and short circuit caused by direct anode contact and continuous high efficiency electric current overcharging.
2)Solutions:
a.Check if the laptop battery is without voltage or electric current.
b.Avoid short circuit.
c.Avoid collision and pressure among batteries.
d.Charge the battery after it automatically powers off , then full charge the battery.
