OPERATING INSTRUCTIONS
1 Intended Use
The product is designed for use with NiMH or NiCd rechargeable batteries. It provides
four independent charging slots for AA / AAA size batteries. This charger can also
optimize and test the maximum capacity of your rechargeable batteries. Each charging
slot has its own display to show various information, such as charging current, battery
voltage, charged capacity, and elapsed time.
The charging current can be selected from 200 mA, 500 mA, 700 mA and 1000 mA.
Batteries of different types (NiMH/NiCd) and sizes (AA/AAA) with different capacities
can be charged at the same time. This charger uses the minus delta voltage (-
Δ
V)
function to determine the charging status. When a battery is fully charged, the charger will
switch to trickle charging automatically. Therefore the battery will be kept at its optimum
capacity. The charger also has built-in overheat detection to protect rechargeable
batteries and charger itself from getting too hot during use. The charger can only be used
with the original power supply included with this charger.
Please operate and store this charger in dry, indoor environment only. This product
