Battery Charger BT-C700
The product is intended to charge and discharge NiCad or NiMH
rechargeable batteries. It provides four independent charging slots for
AA/AAA rechargeable batteries. The charger can also optimize and test
the maximum capacity of the rechargeable batteries. Each charging slot
has its own display to show various information, such as, charging current,
battery voltage, charged/discharged capacity, battery internal resistance
and elapsed charging time.
The charging current can be selected from 200mA to 1000mA. If 4
batteries are needed to be charged, then the maximum current for each
slot is limited to 700mA. If battery in slot 2 or 3 is not present, then the
maximum current for slot 1 and 4 can be selected up to 1000mA.
The charger can charge batteries of different type and size and with
different capacity at the same time. It also integrates the minus delta
voltage (-ΔV) function, which monitors the voltage over the charging cycle.
When 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 includes overheat detection to protect rechargeable
batteries and charger itself from overheating.
Specially design improved charging circuit provides excellent
heating management during high current charging process, which
assures the best charging condition for batteries.
The charger can only be powered by power supply rated 12v/1.0A.
Operate and store it in dry indoor environment only.
This product fulfills European and national requirements related to
electromagnetic compatibility (EMC). CE conformity has been verified and

inadmissible because of safety and approval reasons (CE). Any usage
other than described above is not permitted and can damage the product
and lead to associated risks such as short-circuit, fire, electric shock, etc.
Please read the operating instructions thoroughly and keep them for future
The charger has its backlight turned on after each key press. Back light will
be switched off after 30 seconds when no key is pressed.
The maximum charging capacity can be up to 20,000mAH.

3.1 Product Safety
The product must not be exposed to substantial mechanical strain or
The product must be protected against electromagnetic fields, static
electrical fields, extreme temperatures, direct sunlight and moisture
The manufacturer's instruction for the respective batteries must be
observed, before they are charged.
The product should not be connected immediately after it has been
brought from an area of cold temperature to an area of warm
temperature. Condensed water might destroy the product. Wait until
the product adapts to the new ambient temperature before use.
Sufficient ventilation is essential when operating the charger. Never cover
the ventilating slots of the charger. Please take precautions especially
when ambient temperature is over 35 degrees Celsius and charging
current rate is over 0.5C. If higher charging current applied, it is easier to
build up temperature on batteries.
3.2 Battery Safety
Correct polarity must be observed while inserting the batteries.
Non-rechargeable batteries, rechargeable alkaline batteries (RAM),
lead acid batteries and lithium batteries must not be charged with
this product. There is danger of explosion!
Batteries should be removed from the device if it is not used for a
long period of time to avoid damage through leaking. Leaking or
damaged batteries might cause acid burns when in contact with skin,
therefore use suitable protective gloves to handle corrupted
Batteries must be kept out of reach of children. Do not leave the
battery lying around, as there is risk, that children or pets swallow it.
Batteries must not be dismantled, short-circuited or thrown into fire. Never
recharge non-rechargeable batteries. There is a risk of explosion!
