INTRODUCTION AND FEATURES
Thank you for selecting the Vector Model VEC1090 A 2/10/20 Amp 12 Volt Smart Battery Charger, with Alternator
Voltage Check and Battery Recondition functions. With proper care and use, it will give you years of dependable service.
This battery charger has a high charge rate of up to 20 amps, and low charge rate of up to 2 amps. It is designed for
charging only 12 volt lead-acid batteries - conventional automotive, maintenance free, marine deep cycle and Gel - used
in cars, trucks, farm equipment, boats, RVs and SUVs, lawn mowers/garden tractors, motorcycles, personal watercraft,
snowmobiles, ATVs, trucks and various commercial applications.
Vector Smart Chargers feature 3-Stage High Efficiency Charging Technology Built-in Microprocessor Control that ensures
Fast, Safe and complete Battery Charge (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 3 minutes (based on midsize vehicle battery at 50% charge level). When battery reaches a maximum
safe predetermined voltage, the charger will automatically signal a "BEEP" and 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 battery charge level (step-down regulation mode); Ideal for topping off batteries that have
been in storage. At the conclusion of Stage 3, the unit will BEEP signaling the completion of the charging cycle

FEATURES
• This unit has three charge rate settings, with a 2/10/20A push button switch:
a) 2 amps: smaller batteries as in lawn mowers, snowmobiles, motorcycles, etc.
b) 10 amps: middle sized batteries such as in small cars
c) 20 amps: automobile batteries and light trucks
• 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.
