Preparing To Charge - Stanley BC1509 Instruction Manual

• Never allow battery acid to come in contact with this unit.
• Do not operate this unit in a closed area or restrict ventilation in any way.
• Always turn the battery charger off by unplugging it when not in use.
• DO NOT OPEN THE BATTERY CHARGER — there are no user-serviceable parts inside. Opening the battery charger will void
manufacturer' s warranty.
• Operate battery charger only as described in this Instruction Manual.
• Check battery charger and components periodically for wear and tear. Return to manufacturer for replacement of worn or
defective parts immediately.

PrePAriNg to ChArge

1. Be sure area around battery is well ventilated while battery is being charged.
2. Remove battery completely from boat/airplane or any confined area before charging.
3. If it is necessary to remove battery from vehicle to charge, or to clean terminals, always remove grounded terminal from
battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc.
4. Clean battery terminals, taking care to avoid getting corrosive material in eyes.
5. 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
instructions.
6. Study all battery manufacturer' s specific precautions, such as removing or not removing cell caps while charging, and
recommended rates of charge.
7. Determine voltage of battery to be charged by referring to the vehicle manual. The unit is for charging a 12 volt battery only.
Charger Location
• Locate charger as far away from battery as cables permit.
• Never place charger directly above battery being charged; gases from battery will corrode and damage charger.
• Never allow battery acid to drip on charger when reading gravity or filling battery.
• Never operate charger in a closed-in area or restrict ventilation in any way.
• Marine batteries must be removed and charged on shore.
• Do not set a battery on top of charger.
Connection Precautions
• Connect and disconnect output clamps or vehicle accessory plug only after removing AC cord from electric outlet.
• Never allow clamps to touch each other.
• Attach clamps to battery and chassis as indicated in "Battery Installed in Vehicle" steps 5 and 6, or in "Battery Outside of Vehicle"
steps 2 to 5.
Follow these steps when the battery is installed in a vehicle
WARNING: A spark near the battery may cause an explosion. To reduce risk of a spark near the battery:
1. Position AC and clamp cords to reduce risk of damage by hood, door, or moving engine part.
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
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
WARNING: 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) AWG #6 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. 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 specifically designed for marine use. This unit
is NOT designed for such use.

Charging the Battery
WARNING: TO REDUCE THE RISK OF INJURY OR PROPERTY DAMAGE:
• Always disconnect the AC plug from the AC outlet first before disconnecting the charger from the battery to be
charged.
• Ensure that all installation, operating instructions and safety precautions are understood and always carefully
followed by the steps outlined in the "IMPORTANT SAFETY INSTRUCTION" section at the front of this manual.
1. Plug the battery charger' s power cord into an AC outlet. The LCD screen will display the following (the clamp icon will flash and
the empty battery icon will light):
2. The charger's battery clamps are color-coded. Red is positive; black is negative. Connect the battery clamps correctly to the
corresponding connectors on the battery posts following the steps outlined in the "IMPORTANT SAFETY INSTRUCTION" section
at the front of this manual.
Notes: If the clamps are correctly connected with regard to polarity and the unit is properly connected to the AC outlet, the
LCD screen will display the following:
If the clamps are INCORRECTLY connected with regard to polarity, the LCD screen will display the following (the warning
icon in the triangle and the arrows pointing to the "+" and "–" will flash) and a warning will sound until the clamps are
disconnected:
Unplug the charger; then remove the clamps. Reconnect the clamps properly.
3. When the unit is properly connected, press the battery charge button on the control panel on the front of the unit. The LCD
screen will display the following:
The digital display shows the output current that is charging the battery. The bars on the battery icon will change from empty
to solid (bottom to top) repeatedly and the arrow logos pointing to the "+" and "–" flash.
Notes: The " " icon will appear at the top if the surrounding ambient temperature is higher than approximate 40°C. The " "
icon will appear at the top if the surrounding ambient temperature is lower than 0°C. This is not a fault code, but indicates that
the unit' s temperature compensation feature is operating.
IMPORTANT: If the battery is overheated, the LCD screen will display the following flashing icons:
Disconnect the charger and allow the charger to cool for several minutes. Make sure there is adequate ventilation around the
unit before attempting to charge again.
