• Do not drop a metal tool on the battery. The resulting spark or short-circuit on the
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.
FEATURES
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.
