Hi
Generally, this happens because of the ageing of the battery. Take out your battery and place it in a table and try to spin it, if it spins then it means your battery is bulging and it needs replacement.
if the battery doesnot spins the check this out
Another way is just reverse the polarity of your charger just by inserting the charger in the opposite order in the socket means the charger terminal which was connected to phase should now be connected to neutral and vice- versa. reason the charger is AC-DC converter. By reversing the polarity may help.
