Features - Helvi DISCOVERY 120 Manuel D'instructions

battery of other electrical part may cause an explosion.
• Remove personal metal items such as rings, bracelets, necklaces, and watches
when working with a lead-acid battery.
• A lead-acid battery can produces a short-circuit current high enough to weld a
ring or the like to metal, causing severe burns.
Automatic and Intelligent 9-Stage Charging Curve
The DISCOVERY 120 is controlled by a microprocessor with 9-stage charging cha-
racteristic for charging batteries automobiles, motorcycles, snow mobiles, tractors,
personal watercraft, boats etc.
A microprocessor senses the condition of the battery to provide the right current and
voltage to the battery (charging characteristic). This will give the best effect on char-
ging and give the longest life to battery.
Charging characteristic:
FIG.1
Battery Test and Precharge (Stage 1):
Check the battery voltage to make sure battery connections are good and the battery
is in a stable condition before beginning the charge process
Desulphation (Stage2):
Detects sulfated batteries. Pulsing current and voltage, removes sulfate from the
lead plates of the battery restoring the battery capacity
Soft Start (Stage 3):
Initial battery test to determine battery condition. If the battery is severely dischar-
ged, charger will begin the Soft Start stage. Charging starts with reduced current
until battery voltage reaches a normal condition for charge.
Bulk (Stage 4):
Major charging stage where the battery receives the majority of its charge.
During this stage the battery brought to 75 - 80% of its charge. The charger delivers
maximum current until the terminal voltage has risen to the full charge level for Nor-
mal battery.
