CONNECTING IF BATTERY IS OUTSIDE OF VEHICLE
a) Check polarity of battery posts- For top-mounted battery connectors, the positive post (marked POS, P, +)
usually has a larger diameter than the Negative battery post (marked NEG, N, –). For side-mounted battery
connections the Positive terminal is red, the Negative terminal is black.
b) Attach a 24-inch (minimum length) 6 AWG insulated battery cable to the Negative battery post (marked
NEG, N, –).
c) Connect the Positive (RED) battery clamp to the Positive battery connector (marked POS, P, + or red).
d) Stand as far back from battery as possible, and do not face battery when making final connection.
e) Carefully connect the Negative (BLACK) charger clamp to the free end of the battery cable connected to the
negative terminal. Connect the charger's power cord to a grounded 110/120 volt AC power outlet, and refer
to Appendix A for approximate charging times.
f) Set charger's charge rate to appropriate setting according to battery size.
g) When charging is complete, disconnect cables and clamps in reverse order from which they were connected.
CHARGING TIMES
The VEC1093 A is a fully automatic battery charger. It automatically adjusts the charge rate as the battery
becomes charged and stops charging when the battery is fully charged. If you require some estimate of the time
it takes to charge a battery refer to Appendix A for these details.
100A ENGINE START
The Engine Start Function can supply 100 Amps for engine starting.
Engine Start Procedure
1) Set the 2/10/20/40 amps button to 40 amps mode to activate the 100 amps button befor pressing
the 100A button switch immediately places the charger in the 40 amp charge mode.
2) The digital display will countdown to “000.” This initial charge on the battery makes sure that the battery
is able to take a charge.
3) When the “000” count is reached, the Start Your Engine LED lights. This means the high current circuit is
enabled and will energize when the engine starts cranking.
4) Crank the engine using manufacturer’s guidelines, typically in 3 to 5 second bursts. The high current engine
starting function requires a rest/cooling period between tries. Wait 4 to 5 minutes before a second attempt
at starting the engine.
5) During the rest period, the battery is charging at 40 amps. After engine starts, PRESS the ON/OFF button
switch, disconnect the charger from AC, then frame and battery connections
RECONDITION MODE
NOTE:
BATTERY RECONDITION MODE should only be used with 10 Amp Hour (Ah) or larger capacity lead-acid
batteries. Charge the battery to be treated for 20 minutes, before using RECONDITION Mode. Observe the Digital
Display for any codes. This initial charge will check the battery for shorted cells (F01), open cells or battery too low (or
overcharged) to accept a charge (F02), and to ensure the battery can take a charge. If code (F03) is displayed, change
to the BATTERY RECONDITION MODE.
Whenever a lead acid battery begins to discharge, lead sulfate, an insulator, begins to build up on the battery’s internal
plates. This reduces the ability of the battery to hold a full charge. When that battery has an immediate charge, most of
the lead sulfate is dissolved and the plates are free of this insulation. If a battery remains in a discharged condition over
a longer period of time, the lead sulfate changes to a hard crystalline form, making a full charge difficult to achieve.
