Dear Customer,
Thank you for purchasing the ROSEWILL universal battery charger. This product is an excellent
environmentally friendly choice providing a comprehensive and versatile solution to keeping your
batteries charged when you need them and minimizing battery waste.
The device you have purchased is equipped with the best available technology.
The product meets the requirements of current European and National guidelines. Conformity has
been established and the relevant statements and documents have been deposited at the
manufacturer.
This battery charger has the following features:
Easy to use
Intelligent microprocessor controlled
With negative delta V cut-off function
Rechargeable batteries in all capacities 1-4 pcs sizeAAA,AA,N,C ,D& 1PCS 9V
Recharges batteries in SINGLE or GROUP as the ROSEWILL Charger microprocessor
monitors each charging bay individually
With short-circuit protection

With both LED and LCD display ,the status of each batteries charge cycle can be seen
easily
With individual maximum timer control for overcharge protection.
Charges Ni-Cd (Nickel Cadium), Ni-Mh(Nickel Metal Hydride), Alkaline *,
RAM(Rechargeable Alkaline Manganese)
Note on standard alkaline batteries:
The ROSEWILL Charger can charge most types of alkaline batteries. Please use the setting “ALK”
on the sliding front panel of your charger. Because of the chemistry of standard alkaline batteries
they cannot be recharged nearly as many times as standard rechargeable type batteries like Ni-Cd
or Ni-MH batteries. However, the ROSEWILL Charger uses a recharge current of 130 mAand the
entire charging process is controlled intelligently by microprocessor which can recharge most
standard alkaline batteries to 75-90% of their original capacity upwards of 30+ times depending on
the quality of the battery. Please note standard alkaline batteries should be completely drained
before recharging with your ROSEWILL Charger.
On an environmental note, the cost/performance comparison between standard alkaline batteries
and rechargeable batteries such as Ni-Cd (Nickel Cadmium) and Ni-MH (Nickel Metal Hydride) is
overwhelmingly in favour of rechargeable batteries, we think them the obvious environmental
choice.
We kindly request the user to follow the operating instructions to preserve this condition and to
ensure safe operation.
The device is intended for charging rechargeable Ni-Cd, Ni-MH and RAM batteries of type of

5
Mono (C), Baby (D), Mignon (AA) and Micro (AAA) as well as 9v block batteries. The charger is
also effective at recharging standard alkaline batteries of the same types but at a more limited
capacity as outline earlier. (See “note on standard alkaline batteries”)

-This charger is only suitable for the Ni-Cd(Nickel Cadmium) accumulators and the
Ni-MH(Nickel Metal Hydride ) accumulators and Alkaline
-Don’t use extension cord for connection of the unit.
-Pay attention to the correct polarity during inserting the accumulators.
-Use the unit only at ambient temperatures of 0-40℃.
-Always draw the main plug out of the socket after each use and before cleaning.
-Protect the charger against humidity and heat.
-Never open the unit by yourself; otherwise the warranty will become invalid! Repair can be

hours.
-Never connect other electric units or devices with a damaged main together.
-If the connection cord of this unit is damaged, it must be replaced by the manufacturer, its
service person or a similar qualified person, in order to avoid danger.
PRODUCT DESCRIPTION
1、This charger can charge 4 kinds of batteries Ni-Cd、Ni-MH, RAM &Alkaline.
The Four separate battery charging bays function independently
This enables charging of up to 4 batteries simultaneously, Note :
Batteries must of the same type is Ni-Cd、Ni-MH or alkaline.
Accommodates both AA、AAA、C、D size and 9V batteries.
Battery type is preselected therefore only one type (Ni-Cd, Ni-MH, RAM or alkaline
(Ram Setting)) battery can be charged at one time
This charger uses the latest battery charging technology. It uses “-delta V”deletion
when charging Ni-Cd &Ni-MH battery first, followed by a quick charge. Once the
battery is fully charged, a constant current trickle charge will keep the battery at
optimum capacity.
2、Discharging Ni-Cd only:
Discharge times will very dependant on capacity and charge state, typically the process could
take up to one hour, before the charge cycle commences.
During the discharge process
The indicator LED will glow amber

3、Operation
Please read the following instructions carefully before first use of the ROSEWILL Charger.
Connect the DC plug from the AC adaptor to the DC socket on the rear of the charger.
Insert the AC adaptor into the household supply ensuring the wall socket is switched ON.
This will cause the LED power indicator light to turn on.
Select the required battery type by moving the batter selector switch between Ni-Cd ,Ni-MH
or Ram for alkaline batteries (Switch must not be moved after batteries are loaded)
Insert the required number of batteries into the charger, making sure the correct polarity is
observed (+ is uppermost)
After approximately 2 seconds the ROSEWILL Charger will automatically detect the status
of the battery.
Once battery detection is complete one of the following charging programs will commence.
Ni-Cd batteries: Acharacteristic of a Ni-Cd battery is that it suffers from a memory condition
which means after repeated topping up of the battery the capacity is significantly reduced to
counteract this effect the ROSEWILL Charger will discharge the battery first (LCD linking
“DIS”& energy LCD indicator flashing downward ) whilst LED indicator is illuminated
yellow
Once the discharge cycle is completed , ROSEWILLCharger will begin the quick charge
program (LCD blinking “CHA”& energy level indicator flashing upward ) whilst the LED
indicator illuminates red.
When the battery is fully charged ,( The LCD will show “OK”& energy level indicator
showing full) whilst the LED indicator illuminates green.
Ni-MH & Alkaline batteries: Since neither Ni-MH nor Alkaline batteries have memory
characteristics; ROSEWILL Charger will automatically start the quick charge program. Both

9
LCD & LED will have the same display as for charging Ni-Cd battery.
Providing the fully charged batteries are not removed form the battery charging bays, The
ROSEWILL Charger will automatically trickle charge the battery keeping it at its optimum
capacity.
