General battery charging with constant current mode, so just to control the charging time to complete the charging of thebattery. From the appearance of the battery point of view, it is a nickel-metal hydride battery capacity of 1450 mA.
Its standard charging method:145 mA rechargeable battery rated capacity of 1/10 current 14 to 16 hours the charger measured charging current of 170 mA, the charging time is about 12 hours.
Production of the required components:a transformer, power of about 10W, the voltage of the secondary winding 12 "15V; a 7812 three terminal regulator IC; a IN4008 diode 4 (or 1A/200V rectifier bridge). 2200UF/50V electrolytic capacitors 0.1UF nonpolarized capacitors, one each; resistor a 56 ohm (resistance size according to custom); can hold four batteries of the battery box a; board a Wire.
Description and attention to the point:in accordance with circuit diagram selected components assembled circuit, carefully check to ensure that the welding is correct. Three-terminal regulator IC to install the heat sink. Resistance of the power of 2W, the best flame retardant resistance. Reserve a certain space around him in the circuit board mounted resistance, because resistance also has a larger heat.
The charging timeis calculated as follows: the capacity to be filled is 1450/10 * 14 = 2030 mA charge current of 170 mA Charging time for the 2030/170 about 12 hours according to actual needs, change the resistor size can change the charging current within a certain range, it controls the charging time. However recommended not to use high-current charging, so as not to affect the battery life under normal circumstances. The charger to the battery to recharge a battery, camera 200-300 sheets (LCD viewfinder screen on the Olympus C-860L can be normally open, occasionally using the flash), use has been more than four months, the battery life has been good. To make the charger only spent more than a dozen since the price is high, use is also very satisfactory.
Note:J1 power supply printed circuit board transformer secondary output, J2, the battery pack. D-board silicon rectifier bridge.
