Query: Charger does not fully charge battery

This charger is well made and charges the battery to 4.1 volts, even though the label on the charger indicates: Output 4.2-8.4 V 700mAh. Other brands charges batteries to 4.2 volts. At 4.1 volts, the battery is not fully charged and runs out much sooner The camera shuts down at 3.7 volts, so at 4.1 volts the battery is only 75% charged.
