INTRODUCTION AND FEATURES
Thank you for selecting the Vector(r) Model VEC093 2/10/20/40 Amp 12 volt Smart Battery Charger with Engine
Start, Alternator Voltge Check and Battery Restore modes. With proper care and use, it will give you years of depend-
able service. This model battery charger has a high charge rate of up to 40 amps, and low charge rate of up to 2
amps. It is intended 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, snowmobiles, ATVs, trucks and various commercial applications.
Vector Smart Chargers are microprocessor-based and have a charge curve that has three stages. See Figure 2. Stage
One is essentially a constant current charge. This continues until the connected battery is about 85
percent charged. When Stage One ends, the charger briefly sounds a tone (beep) to indicate a change to
Stage Two, the Absorption Phase. This Stage is essentially a constant voltage phase and supplies approximately 10
percent of the charge. At the end of Stage Two, the charger changes output to Stage Three. Stage Three continues and
turns OFF when the battery reaches full charge. The CHARGING COMPLETE LED lights to indicate charging operation
is complete.
