P 2 / 7 Features and benefits Chargeable for 7.2V - 14.4V batteries Maintenance charge system When the battery is left in the charger , the charger will switch into its " trickle charge " mode and keep the battery fresh and fully charged . Charging light indicating charging process and charging condition with red , green and yellow Longer life of battery The following innovative systems extend the battery's life approx . 50 % longer . 1 . Conditioning charge The charger receives distinctive data ( temperature , history of usage ect . ) from built - in memory chip installed in battery , and decides the most suitable conditions to charge the battery . The conditioning charge will start , when the battery is employed repeatedly under the following conditions , which have bad influence on battery's life . 1 . Charge under high room temperature ( higher than 40 ° C ) 2 . Charge under low room temperature ( lower than 10 ° C ) 3 . Recharge for full charged battery 4 . Over discharge ( continue to discharge battery in spite of machine's power down . ) Even if the cooling system does not work ( because of breakdown of fan or obstruction of vent etc . ) , the conditioning charge functions and starts to charge selecting the most friendly method to the battery . 2 . Cooling system The cooling fan prevents the over heat on battery and keep the optimum temperature for charging . 3 . The charging control system This system controls the output current depending on the temperature on the battery in charging process . Charging light Mark Condition Two green lights flash , when the charger Stand by to charge . is connected to the power source . One red light is on , when the battery indicating the charged condition in 0 - 79 % . cartridge is inserted into the charger . Two red lights are on . indicating charged condition in more than 80 % . Two green lights are on , Finish of charge . Cooling the inserted battery . Two red lights flash , Its temperature is higher than 70 ° C . The charge is stopped until the battery is cooled . Cooling the inserted battery . One red light flashes . Its temperature is lower than 70 ° C . The charge is stopped until the battery is cooled . Impossible to charge , because Red and green lights flash alternately . * the life of battery is over . or * the vent on charger or battery is clogged . Conditioning charge is started . One yellow light is on The charging time can be longer than usual . One yellow light flashes . Breakage on cooling system ( The vent of charger or battery is clogged , or the cooling fan is damaged . ) Charging lights
