Opus PowerFocus BT-C3100 Operating Instructions

Battery Charger BT-C3100 OPERATING INSTRUCTIONS
1. Intended Use
The product is intended to charge and discharge NiCd, NiMH or
3.7v Li-ion rechargeable batteries in size type of 16340, 10440, 14500,
16340, 18500, 18650, 26650, 26500. It provides four independent
charging slots for 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
capacity, battery internal resistance and elapsed charging time.
The charging current can be selected for 200mA, 300mA, 500mA ,
700mA, and 1000mA ( if only bay 1 and/or 4 are used to charging
batteries, current 1500mA and 2000mA can be further selected).
Default charging current is 500mA.
Discharging current can be selected between 200mA, 300mA, 500mA,
700mA and 1000mA. Default discharging current is 500mA
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) for NiCd or NiMh battery charging termination, and for
Li-ion batteries charging to 4.2V with pre-selected constant current.
When battery is fully charged, the charger will switch to trickle
charging automatically. Therefore battery will be kept at its optimum
capacity. The charger also includes overheat detection to protect
rechargeable batteries and charger itself from overheating. When
temperature sensor detects PCB or battery voltage is over 40 degrees
Celsius, then the fan will be turned on automatically. Only when all 6
temperature sensors temperature is measured less than 40 degrees
Celsius, then the fan will be switched off.
The charger can only be powered by power supply rated 12v/3.0A.
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 the relevant statements are available upon request.
Unauthorized conversion and/or modification of the device are
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 reference.
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. Safety Instructions
We do not assume liability for resulting damages to property or
personal injury if the product has been abused in any way or
damaged by improper use or failure to observe these operating
instructions. The warranty will then expire!
3.1 Product Safety
The product must not be exposed to substantial mechanical

strain or strong vibrations.
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, especially area in front of
the cooling fan need to be at least 8cm free open area for enough
ventilation purpose. Please take cautions especially when ambient
temperature is over 35 degrees Celsius and charging current rate is
over 0.5C. If higher charging current applied, it is more easy 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 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.
Batteries must be kept out of reach of children. Do not leave the

battery lying around, as there is risk, that children or pets
