*1 Product Features
*1.1 Application Range
Suitable for 1~4 pieces of AA / AAA Ni-Cd or Ni-MH batteries
*1.2 Microprocessor Controlled
*1.2.1 –Delta v cut off
The charger stops charging once the microprocessor detects the batteries are fully charged.
*1.2.2 Timer Protection
For safety use, charging termination is also controlled by 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
It protects the charger and batteries against incorrectly installing batteries.
*1.3.2 Over Current Protection
Maintains constant charging current during the charging cycle.
*1.3.3 Over Temperature Protection
Protects the batteries from being damaged by overheating, the charging will automatically terminate when the temperature of charger or battery reach to 60oC + 5oC.
*1.4 Trickle Charge After Full Charge
After batteries are fully charged, there will still be a small pulse charge current applying to batteries.
*1.5 Refresh function
The charger has the pre-discharge function, when the battery is discharged to 1.0V, the charger can automatically switch to charging status to charge the battery.
*1.6 Individual LCD display the Charging process
The grid of battery figures rolling in charge status indicates the battery is CHARGING correspondingly. If the battery has been charged for 50% nominal capacity, the first grid will stop rolling; If been charged for 75% nominal capacity, the second grid will also stop rolling; and If been fully charged , the third grid will stop rolling and display full power and end charging.
If you need to pre-discharge the battery, switch to discharge status, the LCD will display the battery is in refresh process, after the battery discharge to 1.0V, the charger can automatically switch to charging.
