A method for compensating for a battery of a hybrid vehicle and an SOC initializing method are provided to measure the internal resistance of the battery accurately by measuring a resistance element when discharging a high current. The internal resistance of a battery is measured when starting a vehicle. If the internal resistance of the battery is larger than the first reference resistance, the generating power is fixed in a regenerative braking operation. If the internal resistance of the battery is larger than the second reference resistance, the replacement of the battery is alarmed. The regenerative braking is performed by the fixed generating power. The battery charging is performed according to the regenerative braking. If the charging current of the battery is larger than the reference charging current, the battery constant-voltage charging control is performed. The SOC is initialized after the constant-voltage charging is completed.
