BC40EWB ManualENSP 022908.qxp
The battery charger is for use on a nominal 120 volt circuit, and has a grounding plug that looks like the plug illustrated in Figure A.
A temporary adapter, which looks like the plug illustrated in Figures B and C may be used to connect this plug to a two-pole
receptacle as shown in Figure B if a properly grounded outlet is not available. The temporary adapter should be used only until a
properly grounded outlet can be installed by a qualified electrician.
D A N G E R – Before using adapter as illustrated, be certain that the center screw of the outlet is grounded. The green-colored rigid
ear or lug extending from the adapter must be connected to a properly grounded outlet. Make certain it is grounded. If necessary,
replace the original outlet cover plate screw with a longer screw that wil l secure adapter ear or lug to outlet cover plate and make
ground connection to grounded outlet.
D A N G E R – Never alter AC cord or plug provided – if it will not fit outlet, have proper outlet installed by a qualified
electrician. Improper connection can result in a risk of an electric shock.
Preparing to Charge
1. Determine voltage of battery to be charged by referring to the vehicle manual.
2. If it is necessary to remove battery from vehicle to charge, or to clean terminals, always remove grounded terminal from
b a t t e ry first. Make sure all accessories in the vehicle are off, so as not to cause an arc .
3. Clean battery terminals. Do not allow corrosion to come in contact with eyes.
4. Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. This helps purge excessive
gas from cells. Do not overfill. For a battery without cell caps (maintenance free), carefully follow manufacturer's charging
i n s t r u c t i o n s .
5. Study all battery manufacturer's specific precautions, such as removing or not removing cell caps while charging, and
recommended rates of charge.
6. Remove battery completely from boat/airplane or any confined area before charging.
7. Make sure the initial charging rate does not exceed battery manufacturer's requirement.
Charger Location
1. Locate charger as far away from battery as cables permit.
2. NEVER place charger directly above battery being charged; gases from battery will corrode and damage charger.
3. NEVER allow battery acid to drip on charger when reading gravity or filling battery.
4. NEVER operate charger in a closed-in area or restrict ventilation in any way.
5. Marine batteries must be removed and charged on shore.
6. Do not set a battery on top of charger.
DC Connection Precautions
1. Connect and disconnect DC output clamps only after removing AC cord from electric outlet.
2. Never allow clamps to touch each other.
3. Attach clamps to battery and chassis as indicated in "Battery Installed in Vehicle" steps 5 and 6, and in "Battery Outside of
Vehicle" steps 2, 4 and 5.
C A U T I O N : A spark near the battery may cause an explosion. Follow these steps to reduce the risk of a spark near the
b a t t e ry when the battery is installed in a vehicle:
1. Position AC and DC cords away from hood, door, or moving engine parts.
2. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
3. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than NEGATIVE (NEG, N, –) post.
4. Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded to chassis (as in most
vehicles), see 5. If positive post is grounded to the chassis, see 6.
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
c a r b u r e t o r, 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
t e r m i n a l .
8. Do not charge the battery while the engine is operating.
9. See operating instructions for length of charge information.
C A U T I O N : A spark near the battery may cause an explosion. Follow these steps to reduce the risk of a spark near the battery
when the battery has been removed from a vehicle:
1. Check polarity of battery posts. P O S I T I V E post (marked POS, P, +) usually has a larger diameter than the N E G AT I V E b a t t e ry
post (marked NEG, N, –).
2 . Attach a 24-inch (minimum length) 8 AWG insulated battery cable to the N E G AT I V E b a t t e ry post (marked NEG, N, – or BLACK).
3. Connect the P O S I T I V E (RED) battery clamp to the P O S I T I V E b a t t e ry post (marked POS, P, + or R E D) .
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 N E G AT I V E
terminal.
6. Press the Charge Button.

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.
N o t e : 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.
• Check unit periodically for wear and tear. Take to a qualified technician for replacement of worn or defective parts immediately.
• Read And Understand This Instruction Manual Before Using This Unit.

B a t t e ry Chargers feature 3-stage, high-efficiency charging technology, built-in microprocessor control that ensures fast,
safe and complete charging of serviceable batteries.
S TAGE ONE
B E E P
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. 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
this phase, the charging voltage remains constant, while the actual charging current is reduced to allow for the maximum
proper internal chemical energy transfer. At the end of Stage 2, the charger will automatically move into Stage 3 charge mode.
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. At the end of Stage 3, the unit will BEEP signaling the completion of the charging cycle.
The Automatic Float Charge feature is ideal for maintaining a battery. It automatically tops off battery as needed, keeping it fully
charged all the time.
