Suuwer SUW012 Manual

SUW012
6V/12V 1.25A DC
Suitable for 6V/12V Normal Lead Acid, Sealed, Leisure, AGM or Gel-
Batteries between 5-75Ah
STORAGE
When not in use, store the battery charger in a dry environment.
MAINTENANCE
Don't try to open the body casing. There are no user-serviceable parts inside. Damage
due to improper use, modifications or attempted repairs lead to the exclusion of liability
and the loss of warranty. The mains supply cord of this device cannot be replaced; if
the cord is damaged, the appliance should be discarded.
PRECAUTIONS WHEN WORKING WITH BATTERIES
 Avoid getting electrolyte on your skin or clothes. It is acidic and can cause burns.
If battery acid contacts skin or clothing, wash immediately with soap and water.
Baking soda neutralizes lead acid battery electrolyte. If electrolyte gets into your
eyes, immediately flood your eyes with running cold water for at least 20 minutes
and get medical attention immediately. Eye protection is therefore recommended.
 Never charge a frozen battery. If battery fluid (electrolyte) becomes frozen, bring the
battery to a warm area to allow the battery to thaw before you begin charging.
 Do not touch the battery clamps together when the charger is on.
 Never use the charger when it has received a hard blow, been dropped, or otherwise
been damaged. Take it to a qualified professional for inspection and repair.
 Prevent the power cord from being stepped on, tripped over, or being damaged.
 Never pull out the plug by the cord when unplugging the charger. Pulling on the cord
may cause damage to the cord or the plug.
 Although it is usually possible without causing problems to charge the battery when
installed, we recommend to remove the battery from the car before charging. When
charging the battery while installed in the car, SUUWER cannot take any
responsibility for harm to your car electronic or the car itself.
 Never smoke or allow a spark or flame in vicinity of battery or engine.
 Always keep metal objects or other materials that can short circuit battery terminals
securely away from the batteries. The resulting spark or short-circuit may cause an
explosion and can produce a current high enough to weld a ring or the like to metal.
Remove personal metal items such as rings, bracelets, necklaces, and watches when
working with starter batteries.
PARTS
 SUW012 main unit
 1 set of crocodile clamps
 1 set of ring terminals (for a permanent installation)

INTRODUCTION
The SUUWER SUW012 is a member of the family of advanced battery chargers
manufactured by SUUWER International Ltd. SUUWER chargers will increase your
battery's performance and prolong its life.
We have taken numerous measures in quality control to ensure that your product
arrives in top condition and will perform to your satisfaction.
Please carefully read and follow the safety and operating instructions. Not
following these instructions may result in a serious accident, including
damaged property or serious injuries.
IMPORTANT SAFETY INSTRUCTIONS
If you are not confident working with 6V/12V DC voltage or are unsure of what you are
doing, consider to seek for professional help e.g. a car garage or your vehicle´s
manufacturer.
Read your vehicle's owner's manual!
Some vehicle manufacturers may have special requirements before charging the
vehicle´s battery. (e.g. fuses that have to be removed or certain security demands).
You MUST NOT connect to 24V or other unsuitable batteries (e.g.
NiCd-batteries). The battery charger is not designed as a power
supply. Not following these instructions could cause serious
personal injury or material damage.
This unit has safeguards against reverse-polarity and short-circuit.
Although it is highly recommended not to touch or connect the red
to the black clamps or to connect the leads in reverse polarity. This
could cause dangerous sparks and electric arcing. Only connect
and disconnect the battery leads when the mains supply is
disconnected.
Use the charger in dry environment only. Do not use the unit close to open fire.
Do not operate the unit in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Please stop using the device, if the unit is
getting very hot, is smoking or is showing any abnormal behaviour. SUUWER is
not liable for any direct or indirect damages or injuries caused by the use of
the device, especially caused by failure to follow these instructions.
TYPE OF BATTERIES
This charger is intended to be used 6V/12V Normal Lead Acid, VRLA, Sealed (MF
Maintenance-Free), Leisure, AGM or Gel-Batteries between 5-75Ah. Do not try to
charge unsupported types of batteries like NiCd.
GASES
When the battery is being charged, you may notice bubbling in the fluid caused by the
release of gas. As the gas is flammable, avoid naked flames, glowing or electrostatically
charged material and sparks in the vincity of the battery. Provide adequate ventilation.
Because of this risk of explosive gas, only connect and disconnect the battery leads
when the mains supply is disconnected.
FEATURES
INTELLIGENT CHARGING
The SUW012 has a built in microprocessor using high frequency technology, that
digitally controls the 4-stages of battery charging: Initialization, constant current,
constant voltage and floating charge. The charger automatically checks the status of
the connected battery and adjusts the charging current. When the battery is fully
charged the charger switches automatically to float charge: the charger can stay
connected to the battery permanently (ideal for seasonally used vehicles).
Charging characteristic:
1. Initialization: Initialize diagnostic battery performance and desulfating the battery
through 17V pulse.
2. Bulk: Major charging stage where the battery receives the majority of its charge.
During this stage the battery brought to 75 - 80% of its charger. The SUW012
charger delivers maximum current until the terminal voltage has risen to the full
charge level for Normal battery.
3. Absorption: Completes the charge up to virtually 100% at a constant voltage. The
current tapers off after the current reached the minimum level.
4. Float: Maintenance charging at constant voltage, keeping the batteries at 100%
charge. Float mode chargers indefinitely without damaging the battery.
