Operating Instructions - Schumacher Electric 102-3 Manual Del Usuario

CLAMPS REVERSED (red) LED flashing: The connections are reversed.
BAD BATTERY (red) LED lit: The charger has detected a problem with the battery.
See Troubleshooting for more information.
RATE SELECTION BUTTON
Use this button to select one of the following:
6<>2A CHARGE/MAINTAIN – For charging small and large batteries. Not recommended for industrial
applications. The charger will automatically adjust the charging current, based on battery size, in order to
charge the battery completely, efficiently and safely.
BOOST – For quickly adding energy to a severely discharged or large capacity battery prior to Engine Start.
The unit will automatically switch to 6A<>2A Charge after the Boost operation has completed.
ENGINE START – Provides additional amps for cranking an engine with a weak or run-down battery.
Always use in combination with a battery.
NOTE: See Operating Instructions for a complete description of the charger modes.
BATTERY TYPE BUTTON
Use this button to select the battery type.
STD – Used in cars, trucks and motorcycles, these batteries have vent caps and are often marked "low
maintenance" or "maintenance-free". This type of battery is designed to deliver quick bursts of energy (such
as starting engines) and has a greater plate count. The plates are thinner and have somewhat different
material composition. Regular batteries should not be used for deep-cycle applications.
AGM – The Absorbed Glass Mat construction allows the electrolyte to be suspended in close proximity with
the plate's active material. In theory, this enhances both the discharge and recharge efficiency. The AGM
batteries are a variant of Sealed VRLA (valve regulated lead-acid) batteries. Popular uses include high-
performance engine starting, power sports, deep-cycle, solar and storage batteries.
GEL – The electrolyte in a GEL cell has a silica additive that causes it to set up or stiffen. The recharge
voltages on this type of cell are lower than those for other styles of lead-acid battery. This is probably the
most sensitive cell in terms of adverse reactions to overvoltage charging. Gel batteries are best used in
VERY DEEP cycle application and may last a bit longer in hot weather applications. If the wrong battery
charger is used on a gel cell battery, poor performance and premature failure will result.

11. OPERATING INSTRUCTIONS

WARNING: A SPARK NEAR THE BATTERY MAY CAUSE AN EXPLOSION.
NOTE: This charger is equipped with an auto-start feature. Current will not be supplied to the battery
clamps until a battery is properly connected. The clamps will not spark if touched together.
CHARGING A BATTERY IN THE VEHICLE
1. Turn off all the vehicle's accessories.
2. Keep the hood open.
3. Clean the battery terminals.
4. Place the charger on a dry, non-flammable surface.
5. Lay the AC/DC cables away from any fan blades, belts, pulleys and other moving parts.
6. Connect the battery, following the precautions listed in sections 6 and 7.
7. Connect the charger to a live, grounded 120V AC outlet.
8. Select the battery type and charge rate.
9. Press the Start/Stop button to begin charging immediately. If the button is not pressed, charging will
begin within ten minutes. It will finish automatically.
10. When charging is complete, disconnect the charger from the AC power, remove the clamp from the
vehicle's chassis, and then remove the clamp from the battery terminal.
CHARGING A BATTERY OUTSIDE OF THE VEHICLE
1. Place battery in a well-ventilated area.
2. Clean the battery terminals.
3. Connect the battery, following the precautions listed in sections 6 and 7.
