INTRODUCTION
Thank you for selecting the
40/20/10/4 Amp Smart Battery Charger.
With
proper care and use, it will give you years of dependable service. This battery
charger has a high charge rate of up to 40 amps, a low charge rate of 4 amps and
110 amps of engine starting power. 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
and various applications.
Smart Battery Chargers feature 3-stage high-efficiency charging technology built-in
microprocessor control that ensures fast, safe and complete charging of serviceable
batteries.
Charge Curve
Stage One —
Rapid Start Charge at 40 amps delivers maximum charging
amperage to “wake up” any serviceable 12 volt battery and allows for quick engine
starting in just 1 minute (based on a 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.

5. For negative-grounded vehicle, connect POSITIVE (RED) clamp from battery charger to POSITIVE
(POS, P, +) ungrounded post of battery. Connect NEGATIVE (BLACK) clamp to vehicle chassis or
engine block away from battery. Do not connect clip to carburetor, fuel lines, or sheet-metal body
parts. Connect to heavy gauge metal part of the frame or engine block.
6. For positive-grounded vehicle, connect NEGATIVE (BLACK) clamp from battery charger to
NEGATIVE (NEG, N, –) ungrounded post of battery. Connect POSITIVE (RED) clamp to vehicle
chassis or engine block away from battery. Do not connect clip to carburetor, fuel lines or sheet-
metal body parts. Connect to a heavy gauge metal part of the frame or engine block.
7. When disconnecting charger, disconnect AC cord, remove clamp from vehicle chassis, and then
remove clamp from battery terminal.
8. Do not charge the battery while the engine is operating.
9. See operating instructions for length of charge information.
Follow these steps when the battery has been removed from a vehicle. A spark near
the battery may cause an explosion. To reduce risk of a spark near the battery:
1. Check polarity of battery posts. The POSITIVE post (marked POS,P, +) usually has a larger diameter
than the NEGATIVE battery post (marked NEG, N, –).
2. Attach a 24-inch (minimum length) 6 AWG insulated battery cable to the NEGATIVE battery post
(marked NEG, N, –).
3. Connect the POSITIVE (RED) battery clamp to the POSITIVE battery post (marked POS, P, + or red).
4. Stand as far back from the battery as possible, and do not face battery when making final
connection.
5. Carefully connect the NEGATIVE (BLACK) charger clamp to the free end of the battery cable
connected to the NEGATIVE terminal.
6. Set the charge rate to appropriate setting according to battery size.
7. When disconnecting charger, always do so in reverse sequence of connecting procedure and break
first connection while as far away from battery as practical.
Note:
A marine (boat) battery must be removed and charged on shore. To charge it
on board requires equipment specially designed for marine use. This unit is
NOT designed for such use.
SAVE THESE INSTRUCTIONS
This device complies with part 15 of the FCC rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If equipment does cause
harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more
of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
