INTRODUCTION AND FEATURES
Congratulations and thank you for selecting the Vector Model VEC1093 A 2/10/20/40 Amp 12 Volt Smart Battery
Charger with 100 amp Engine Start with Alternator Voltage Check and Battery Recondition functions. With proper care
and use, it will give you years of dependable service. This model battery charger has a high charge rate of up to 40
amps, and low charge rate of up to 2 amps and 100 amps of engine starting power. It is designed for charging only 12
volt lead-acid batteries - maintenance free, conventional automotive, marine deep cycle and gel - that are usually used
in cars, trucks, farm equipment, boats, RVs and SUVs, lawn mowers and garden tractors, motorcycles, personal
watercraft, snowmobile, ATVs, trucks and various commercial applications.
Vector Smart Chargers are microprocessor-based and have a charge curve that has three stages. (See FIGURE 2)
Vector Smart Chargers are microprocessor-based and have a charge curve that has three stages. (See Figure 2). Stage
One - Rapid Start Charge- delivers maximum charging amperage to “wake up” any serviceable 12 Volt battery and
allows for quick engine starting in just 1 minutes (based on midsize vehicle battery at 50% charge level). When battery
reaches a maximum safe predetermined voltage, the charger will automatically move into Stage 2 of the charging
process. Stage Two- Absorption Charge maintains the maximum possible charge at a constant safe predetermined
voltage. During the phase, voltage absorption regulation charge, the charging voltage remains constant, while the actual
charging current is reduced to allow for the maximum proper internal chemical energy transfer. Stage Three- Top-Off
Charge voltage is automatically maintained and reduced to a predetermined level while current is adjusted for a safe,
effective 100% battery charge (step-down regulation mode); Ideal for topping off batteries that have been in storage.

FEATURES
• The unit has four charge rate settings, controlled by a 2/10/20/40 switch button:
a) 2 amps: smaller batteries as in lawn mowers, snowmobile, motorcycles, etc.
b) 10 amps: middle sized batteries such as in small cars.
c) 20 amps: automobile batteries.
d) 40 amps: large truck batteries, banks of RV batteries.
• Microprocessor controlled for proper operation and for fault detection.
• Large Lighted Digital Display, shows charging current, and codes that indicate faults, and modes of operation and
timeout of functions.
• High Frequency operation for pure DC output.
• Rapid charging three stage output.
• Heavy-duty cables and clamps are corrosion-resistant.
• Connect to side or top-mount battery terminals.
• Rugged case with baked on finish, plus sturdy carry handle.
• Self storage of cables and clamps.
• Ideal during winter season when vehicle's starting performance is reduced by cold or extreme weather conditions.
• Single beep tone indicates a button is pressed or a mode change occurs.
• Battery Recondition mode provides "desulfation" of battery plates to improve battery performance.
• Alternator Voltage Check can determine if the alternator output is within a typical voltage range.
