1 Product Features 1.1 Application Range Suitable for 1~4 pieces of AA /1~4pieces of AAA Ni-Cd or Ni-MH batteries 1.2 Microprocessor Controlled 1.2.1 Automatically cut off power The charger stops charging once the microprocessor detects the batteries are fully charged. 1.2.2 Timer Protection For safety use, charging termination is controlled with timer. 1.2.3 Defective and Non-rechargeable battery detection Safety Protection for using the charger if you attempt to charge defective or non-rechargeable batteries. If you charge non-rechargeable and rechargeable together, detection may not work properly. Charging rechargeable alkaline batteries may result in battery leakage. 1.3 Other protections 1.3.1 Reverse Polarity Protection Protects the charger and batteries against incorrectly installing batteries. 1.3.2 Over Current Protection Maintains constant charging current during the charging cycle. 1.4 Low Battery Leakage Current If the battery charger is not connected to AC power and the batteries are left in the charger, the charger will discharge the batteries in a certain amount of current. 1.5 Trickle Charge After Full Charge After batteries are fully charged, there will still be a small pulse charge current applying to batteries. 1.6 Charging Indicators Red indicates CHARGING Green indicates batteries are FULL charged and on trickle charging Red/Green Flashing indicates WARNING of Defective batteries Short circuit 2 Electrical Performance and Technical Parameter 2.1 Input : 100~240VAC 50/60Hz 10W ;12~14V DC 1.0A (Max. ) 2.2 Charging Currents AA/AAA? 700~800mA for 1~2 batteries AA/AAA? 300~400mA for 3~4 batteries 2.3 Charging Voltages 1.4V for individual charge 2.4 Battery Leakage Current Maximum 0.5mA 2.5 High-Voltage Shock Test Method: Connecting high voltages 3000VAC for 1 minute between input and output terminals. Requirement: Current leakage between input/output must be less than 10mA, and the unit should still work as normal. 3 Mechanical Tests and Requirements 3.1 Drop test Drop from 3 feet height onto an oak board of 10 mm thick. The test shall be carried out 3 times respectively in 3 different surfaces of the case. Requirement: The charger should still meet High-Voltage Shock Test. 3.2 Bending te
