Product Feature
Congratulations on your purchase of the INVATEC SC-7 7-Step fully automatic switch mode battery charger and
maintainer, designed for charging a variety of 12V and 24V Lead-Acid rechargeable batteries, widely used in boats,
cars, trucks and several other vehicles. The batteries may be of various types i.e. WET/Flooded (Liquid Electrolyte), GEL
(Gelatin type Electrolyte, absorbed into the plates), AGM (Absorbed Glass Mat), MF, VRLA (Valve Regulated Lead Acid)
batteries. Their capacity range from 12V/14Ah to 12V/230Ah and 24V/14Ah to 24V/120Ah. The INVATEC SC-7 battery
charger also charges batteries in cold conditions. Using state-of-the art technology, the charger enables the recharging
of the batteries to almost 100% of their original capacity. It recovers slightly sulphated batteries. It diagnoses and
rescues drained battery. It provides trickle charge and maintenance charging which increases battery life and gives
superb performance. The INVATEC SC-7 battery charger provides six output options to meet numerous requirements
i.e. 14.4V, 14.7V, 28.8V, 29.4V, 13.6V/SUPPLY and 16V/BOOST. It has 10 Stage charging strategy i.e. Pulse charge,
7.0A, 5.0A, 3.5A, 3.0A, 1.5A, 200mA, Boost charge, Maintenance & Power Supply. It has memory function. The charger
returns to last selected mode automatically when power is switched on (this feature is unavailable for 13.6V/SUPPLY
and 16V/BOOST mode). For repetitive charging process, this is a very useful feature. However different charging mode
could be selected by pressing the “MODE” button. It also features low back current drain and low ripple.
Product Safety Feature
•
Electronically safe against user errors. The charger will not damage vehicle electronics. It is totally safe for months long connections and maintenance of irregularly or seasonally used batteries even while the charger is still connected
to the vehicle. It provides optimal condition without damage. No risk of over-charging!
•
Full protection against wrong connection and against short circuit ensures safe charging operation.
•
Provided with Spark protection mechanism. This feature does not activate when the charger is in Supply mode. The
charger will not begin operation upon connection to the battery unless charging mode has been selected. This
embedded feature eliminates the possibility of a spark that often appears during connections.
•
Fully controlled by internal MCU (Micro-Computer-Unit), which makes it faster, powerful, reliable and smarter. It detects
the state of charge of the battery plugged into it and initiates charging.
•
Dust and splash proof (IP65) approval. Approved for Outdoor use.
•
Double insulated
Safety Information
•
INVATEC SC-7 charger is designed for charging 12V 14-230Ah and 24V 14-120Ah Lead-Acid rechargeable batteries. Do not use it for any other
purposes. It may cause an explosion.
WARNING! DO NOT ATTEMPT TO CHARGE A NON-RECHARGEABLE BATTERY (PRIMARY CELLS).
•
Before charging make sure the input power is as per rated specifications, otherwise the charging performance may be seriously affected.
•
Do not use battery charger for charging dry-cell batteries. They may burst and cause injury to persons and damage to property.
•
Never charge a frozen battery.
•
Never charge a damaged battery.
•
Do not use the charger with a damaged cable 17 . It must be replaced by the manufacturer, its service agent or similarly qualified technician in
order to ensure safety.
•
Do not operate charger if it appears to be damaged or malfunctioning. Take it to qualified person for inspection and repair.
•
Do not disassemble charger, incorrect reassembly may result in electric shock or fire. Locate charger as far away from battery as DC cable permit.
•
Never place charger above battery being charged, gases from battery will corrode and damage charger.
•
While charging always use safety glasses, gloves, protective clothing and keep your face away from the battery.
•
Remove metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery. A lead-acid battery can produce a
short-circuit current high enough to melt such metallic objects, causing a severe burn.
•
Explosion hazard! A battery being charged could emit explosive gasses. Avoid smoking or open sparks or flames in the vicinity of the battery.
Explosive and flammable substances such as fuel or solvents should not be kept in the vicinity of the charger or the battery.
•
Disconnect the supply before making or breaking connections to the battery.
•
While connecting the charger to the battery, maintain right polarity connection and avoid short-circuiting.
•
Connect the appropriate DC clip to the battery post which is not connected to the automobile chassis. (The battery terminal not connected to the
chassis has to be connected first.)
•
Connect the other DC connector to the chassis, away from the battery and fuel line.
•
The connector to be fixed to the positive pole shall be coloured red and that to be connected to the negative pole shall be coloured black.
•
Then connect the battery charger to the supply mains.
A3
Locate Charger
•
Locate the charger as far away from battery as the DC cord permits.
•
While charging do not place charger directly above or below the battery. Gases or fluids from the battery may corrode
and damage the charger.
•
Never allow battery acid to drip on the charger.
•
Charging should be carried out in a well-ventilated, weather protected facility.
Battery Type & Settings
The following recommendations should only be referred to as guidelines. For precise details, you must refer to battery
manufacturer for instructions.
Symbol Mode Settings Details
This mode is normally suitable for 24V WET,
MF and GEL batteries.
This mode is recommended for several 24V
AGM batteries. It is also suitable for charging
batteries in sub-zero temperatures.
This mode is normally suitable for 12V WET,
MF and GEL batteries.
This mode is recommended for several 12V
AGM batteries. It is also suitable for charging
batteries in sub-zero temperatures.
a)
Maintenance of 12V Lead-Acid rechargeable batteries:
This mode is suitable for maintenance of
12V batteries with capacity range from
14-230Ah. The charger delivers a constant
voltage of 13.6V. This is maintenance mode
for applications where maximum capacity
from the battery is required such as Golf
Carts, Floor Sweepers etc.
b) Power source: INVATEC SC-7 battery
charger is also used as a power supply,
without attaching a battery in this mode.
The charger delivers 13.6V/5A. Spark free
function is inactivated. However reverse
polarity protection function still works.
BOOST
This mode is mainly applied for recovering 12V
batteries with capacity range from 14-230Ah in
normal condition. To recover severely discharged
batteries due to stratified acid, this mode is useful.
High voltage (17V max) at 1.5A is applied for a
maximum period of 3 hours. A fully charged battery
gives faster result. High voltage may cause some
water loss. For optimal efficiency and minimum risk to
vehicle’s / boat’s electronics, battery must be
disconnected.
•
Do not cover the charger while charging.
•
Do not touch the battery clips together when charger is connected with mains.
•
After charging, disconnect the battery charger from supply mains. Remove the chassis connection and the battery connection, respectively. This
will reduce back drain current.
•
Charging must be ceased immediately if battery is found to be too hot or leaks out liquid during charging.
•
In case of malfunction or damage, immediately disconnect the charger from the mains.
•
Do not use vehicle when charging permanently installed batteries.
•
During charging the battery must be placed in a well ventilated area.
•
Danger of chemical burns! Battery acid is highly corrosive. If your skin or eyes come into contact with acid, immediately rinse the affected part of
the body with excessive water and seek medical advice.
•
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
•
Children should be supervised to ensure that they do not play with the appliance.
•
Ensure that charger switches to maintenance charge mode, before it is left unattended and connected for long time. If this stage does not arrive
within 73 hours (max), the charger must be disconnected manually.
