Satish. Sounds like your charger is hitting a mAh limit or a time limit. I am not familiar with the ICE but there should be an option to increase the mA limit or time limit. If you are charging at 3A lets say, then some chargers will stop charging when 3000mAh has been reached. The charger thinks the battery is 100% full even though the voltage is not to 4.2V.
