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 110/120VAC power outlet, and refer to Appendix A for
approximate charging times.
f) Set charge rate to appropriate setting according to battery size.
g) When charging is complete, disconnect cables and clamps in reverse order they were connected.
CHARGING TIMES
The VEC1090 A, fully automatic, Smart Battery Charger will automatically adjust the charge rate as the battery becomes
charged and stops charging when the battery is fully charged. For estimates of the time it takes to charge a battery refer
to Appendix A for details. Deep cycle batteries may need longer charging time. It is recommended to repeat the
charging cycle a second time beginning with the 2A rate.
BATTERY RECONDITION MODE
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 up to 20 minutes, before using RECONDITION Mode. Observe the Digital Display
for any codes that may be indicated during this period. 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.
The BATTERY RECONDITION mode sends a sequence of electronic pulses into the serviceable battery (over 24 hour
period), enabling the sulfates to once again accept and release energy so the battery will perform at a greater capacity.
Battery Recondition mode automatically operates and then "times out" after 24 hours. When a smaller battery is treated,
Battery Recondition mode can be manually stopped after 12 hours of treatment.
1) START the Battery Recondition function by pressing the Battery Recondition switch button.
2) The first 5 seconds the display will show “des” then change to moving bars for the remainder of the timing period.
3) After 24 hours the timer will stop the operation. The digital display will show the circulating pattern
4) If the battery is NOT fully charged, you should charge the battery until “FUL” is displayed on the digital display.
NOTE:
BATTERY RECONDITION function does not charge any battery. Charging is a separate function. The battery
being serviced does not have to be installed in a vehicle. Follow the instructions for Connecting If Battery
is Outside of Vehicle.
NOTE:
The Battery Recondition function is ideal to use on a regularly scheduled maintenance basis to keep batteries
in top performing condition.
NOTE:
If the battery still fails to take a charge after the first 24 hour period, then repeat for one more full charging
cycle. If the battery still fails to accept or hold a charge, then battery needs replacement and should
be re-cycled.
