P 2 / 4 Features and benefits Ideal charging system in this class with the following installations * Controlling by micro computer : The installed micro computer perceives the full charged condition , and control the optimum way to stop the charging process , from the followings . A ) Minus delta V system : Stop the charging process with perceiving the battery's voltage drop . B ) Delta T system : Stop the charging process with perceiving the change of battery's temperature . ( This system is applied to only the charger of 4 terminal - type . ) C ) T system : Stop the charging process with perceiving the battery's temperature which is input in the micro computer in advance . For instance the charging process is to be stopped at 45 ° C for 1.3Ah battery , and at 60 ° C for 1.7 - 2.2Ah battery . D ) Timer system : Stop the charging process in 150 minutes after starting the charge , if the full charged condition would not be perceiving with any of the above 3 systems . Minus delta V system 1 Battery's voltage T system 2 Heated battery's temperature . 1 It can not be charged Battery's voltage completely . and temperature 2 3 Battery's normal temperature Delta T in charging process system The process is stopped by delta T system . 3 Charging time Full charged line * Current transforming system : The built - in " High - Frequency Tranceformer " supplys the charging current as follows . 1 . Convert alternative current into direct current . 2 . Re - convert the above direct current into alternative current , however , high frequency of approx . 150 - 160 kHz in this stage . 3 . Reduce the voltage to the battery's voltage . The feature of " High - Frequency Tranceformer " is light and compact comparing with the existing trance . * Constant output current ( charging current ) : By keeping the output current ( Ampere ) in the constant level , it is possible to stop the charging process with perceiving the battery's voltage drop exactly . Namely it is possible to perceive the full charged condition by the above " Minus delta V system " . * Trickle charging mode : Continue to produce very small charging current ( approx . 40mA ) for full charged battery left in charger . The chargeable batteries Battery's type No . * Charging time Capacity 7.2 V 9.6 V 12 V 14.4 V 7000 7100 9000 9100 1200 1200A 1420 Approx . 30 min . 1.3Ah 9100A 1210 1220 7120 9120 - Cd 9001 9101 1201 1201A Ni Approx . 40 min . 1.7Ah 7001 9101A 7002 9002 9102 1202 1422 2.0Ah Approx . 45 min . 9102A 1222 9122 7033 9033 9133 1233 1433 Approx . 50 min . 2.2Ah - MH 9134 1234 1434 Approx . 60 min . 2.6Ah Ni 9135 1235 1435 Approx . 70 min . 3.0Ah 9135A 1235A < Note > The charging time can be different from conditions to conditions of batteries and room temperature .

Repair < 1 > The circuit board can not be repaired , because the circuit itself are molded on the board . It has to be replaced as a set with new one . < 2 > In case of damaged varistor or fuse , they can be repaired according to the following procedure without replacing the circuit board . ( 1 ) How to find broken varistor a . In case that the surface of varistor ( ref . to the following illustration ) has broken or has become black , and fuse has been cut , the varistor has been damaged . b . Varistor can be damaged easily , if the charger is plugged in a double voltage of the rating one . c . It is considered that the varistor has been broken for other reasons , if the fuse is broken while the surface of varistor is not damaged . In this case circuit board has to be replaced .
