BATTERY WARNINGS

DANGER! RISK OF BATTERY EXPLOSION FROM HYDROGEN GAS. MAY RESULT IN BLINDNESS, SERIOUS INJURY, PERMANENT DISFIGUREMENT AND SCARRING.


Batteries generate explosive hydrogen gas, even during normal operation. People have been injured by battery parts flying in an explosion. They can explode under normal operating conditions, such as starting your car. They can explode under abnormal conditions, such as jump starting, or if short circuited by a tool. They can explode in a parked car or sitting on a table.

To help reduce the risk of these dangers and injury, it is of the utmost importance that each time before using your charger, you read and understand this manual, and any warnings and instructions by the battery manufacturer. Follow these instructions exactly.
TO HELP REDUCE THIS RISK:

  1. Wear Personal Protective Equipment
  2. Avoid Flames and Sparks Near Battery and Fuel
  3. Reduce Explosive Gas (hydrogen)
  4. Stay Away From Battery When Possible
  5. Avoid Contact With Battery Acid
  6. Avoid Overcharging Batteries
  7. Follow Other Manufacturers' Recommendations

ELECTRICAL WARNINGS

DANGER! RISK OF ELECTRICAL AND FIRE HAZARD. MAY RESULT IN DEATH, SERIOUS INJURY, SHOCK OR BURNS.
TO HELP REDUCE THIS RISK:

This charger, like all electrical products, MUST be treated with respect. Follow these instructions to reduce electrical hazard risk.
  1. PROPER GROUNDING AND AC POWER CONNECTION
  2. Remove Jewelry
  3. Avoid Charger Abuse
  4. Proper Use of Charger and Wiring
    RECOMMENDED PROPER WIRE SIZE (AWG) IN
    EXTENSION CORDS FOR BATTERY CHARGERS
    Charger's AC Input Rating Length of Cord (feet)

AUTOMOTIVE WARNINGS

DANGER! RISK OF FLYING PARTS IF USED NEAR MOVING ENGINE PARTS. MAY RESULT IN DEATH, BLINDNESS, SERIOUS INJURY, PERMANENT DISFIGUREMENT AND SCARRING.
TO HELP REDUCE THIS RISK:


GENERAL INFORMATION

The warnings are important. Remember, our address is on the charger, if you should lose these Safety Instructions send a stamped, self addressed envelope for a new set.

The following models are covered by these instructions. The safety and connection part of these instructions apply in general to all battery chargers.

Manual Chargers: (You must unplug them when battery is charged.)
Includes all our models that begin with a single letter: A, B, C, F.

Manual Chargers with Engine Starting Feature:
Includes all our models that begin with the letters: J, L, FC.

Automatic Chargers:
Models with initial letters CR, BR, ER, R or end with the letter A.


Operating Instructions

A spark near the battery may cause a battery explosion. To reduce risk of a spark near the battery when you connect the charger clips, ONLY connect one clip to the battery. Then, take the second clip and connect it to the car frame or engine block. If a spark should occur then, it will be far away from the battery. This type of connection works because every car battery has one cable which is connected to the body or car frame. This is called the ground cable. On most cars this cable is connected to the NEGATIVE terminal of the battery. This is called a NEGATIVE GROUND. Most cars made in the U.S.A., Europe, and Asia in the last twenty years have negative grounds.

Battery Polarity: A battery has two poles or posts. The positive battery post is usually marked POS, P, or + and is larger than the negative post which is usually marked NEG, N, or -.

The polarity of the charger and the battery MUST ALWAYS match to avoid damage to battery and charger. On a negative ground car: connect the positive (red) charger clip to the positive battery post first; then connect the negative (black) clip to negative ground (car frame or engine block). If you are not sure what type of ground your car has, have it checked before using charger.

Honestly now, did you review the safety instructions before connecting your charger? Follow these three steps in order. Go to STEP 1.

STEP 1. CONNECTING THE CHARGER TO BATTERY

A. CHARGING BATTERY IN VEHICLE

If car has negative ground: (Most cars do, but if you are not sure have it checked.)
  1. Connect POSITIVE (RED) charger clip to POSITIVE post of battery. Some newer cars have a remote positive terminal located away from the battery. Use this remote terminal for charging connections. See your car's owners manual.
  2. Next connect NEGATIVE (BLACK) charger clip to car frame or engine block away from battery.
CAUTION: 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. DO NOT face battery when making final connection. Go to STEP 2.
Charger connection diagram. You need to see it. Send a SASE to get it.

If car has positive ground: (Most cars DO NOT, be sure to check.)

  1. Connect NEGATIVE (BLACK) charger clip to NEGATIVE ungrounded post of battery.
  2. Next connect POSITIVE (RED) charger clip to car frame or engine block away from battery.
CAUTION: 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. DO NOT face battery when making final connection. Go to STEP 2.

B. CHARGING BATTERY OUTSIDE VEHICLE

  1. Connect POSITIVE (RED) charger clip to POSITIVE post of battery.
  2. Position yourself and free end of cable as far away from battery as possible - then connect NEGATIVE (BLACK) charger clip to free end of cable. DO NOT face battery when making final connection. Go to STEP 2.

STEP 2. TURNING THE CHARGER ON

STEP 3. TURNING THE CHARGER OFF

NR = Not Recommended for this size battery.

Charging times for your battery may be different from these. If your battery is only half discharged you will need only half the time to charge.

Some old batteries may not accept a charge and will heat up on charging. CAUTION: If at any time the battery gets hot (above 125 degrees F) or acid comes out of vent caps, STOP charging. Have your battery checked. Charging may not be possible. It may have to be replaced.

CAUTION: Manual Chargers - If you feel your battery is not charged after these times, have it checked. Charging for longer times may damage battery. Automatic Chargers - After these times, or slightly longer, if automatic chargers are still charging at a low rate near 2 to 3 amperes suspect the following two battery problems. 1) Sulfated battery (worn out), 2) shorted cell in battery. Stop charging and have battery checked.

Charging times for the car batteries are based on their Reserve Capacity ratings [RC]. We assumed the batteries were fully discharged.

Charging times for the motorcycle and deep cycle batteries are based on their Ampere Hour ratings [AH]. The motorcycle/garden tractor batteries and deep cycle batteries were assumed to be 70 per cent discharged.

There is no relationship between Cold Cranking rating [CCA] and charge time. Two batteries may have the same CCA rating, but very different RC ratings. ALWAYS use RC or AH ratings to determine charge time. If you do not know the rating for your battery, ask your battery dealer.


TROUBLE SHOOTING

  1. No DC Output On Ammeter When Charger Is On.
    a) Unplug the charger and make sure connections are secure.
    b) Check for wall outlet for power.
    c) DC circuit breaker is tripped. See "Charger Overload" below.
    d) A dead battery (Specific Gravity near 1.000) shows very low output on ammeter. After 15 to 20 minutes the indicated current rises and normal charging occurs.
  2. Charger Overload.

    Listed below are the conditions that can cause the circuit breaker to trip:

  3. Charge Rate Does Not Go To Full Amp Rating Of Charger And/Or Falls Quickly When Charger Is Turned On.
  4. Current Indicated On Ammeter Falls Slightly Showing No Further Change.
