To reduce the risk of electric shock, unplug the charger from the outlet before attempting any maintenance or
cleaning. Turning off controls will not reduce this risk.
WARNING: RISK OF EXPLOSIVE GASES.

WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST IMPORTANCE THAT YOU FOLLOW THE INSTRUCTIONS EACH TIME YOU USE THE CHARGER.
To reduce the risk of battery explosion, follow these instructions and those published by battery manufacturer and manufacturer of any equipment you intend to use in vicinity of the battery. Review cautionary markings on these products and on the engine.

PERSONAL SAFETY PRECAUTIONS

Consider having someone close enough by to come to your aid when you work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
Wear complete eye protection and clothing protection. Avoid touching eyes while working near the battery.
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye,
immediately flood eye with running cold water for at least 10 minutes and get medical attention immediately.
NEVER smoke or allow a spark or flame in the vicinity of the battery or engine.
Be extra cautious to reduce risk of dropping a metal tool onto the battery. It might spark or short-circuit a battery or another electrical part that may cause an explosion.
Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery.
A lead-acid battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing a severe burn.
Use charger for charging only LEAD-ACID (STD, AGM or GEL) rechargeable batteries. It is not intended to supply power to a low voltage electrical system other than in a starter-motor application.
Do not use a battery charger for charging dry-cell batteries that are commonly used with home appliances.
These batteries may burst and cause injury to persons and damage to property.
NEVER charge a frozen battery.

PREPARING TO CHARGE

If necessary to remove the battery from the vehicle to charge, always remove the grounded terminal from the battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc.
Be sure area around the battery is well ventilated while the battery is being charged.
Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
Add distilled water in each cell until battery acid reaches the level specified by the battery manufacturer. Do not
overfill. For a battery without removable cell caps, such as valve-regulated lead-acid batteries, carefully follow the manufacturer’s recharging instructions.
Study all battery manufacturer’s specific precautions while charging and recommended rates of charge.
Determine voltage of battery by referring to car owner’s manual and make sure that output voltage selector switch is set at the correct voltage. If the charger has an adjustable charge rate, charge the battery initially at the lowest rate.

CHARGER LOCATION

Locate charger as far away from battery as DC cables permit.
Never place charger directly above battery being charged; gases from battery will corrode and damage the charger.
Never allow battery acid to drip on the charger when reading electrolyte specific gravity or filling the battery.
Do not operate chargers in a closed-in area or restrict ventilation in any way.
Do not set a battery on top of the charger.

DC CONNECTION PRECAUTIONS

Connect and disconnect DC output clips only after setting any charger switches to the “off” position and removing the AC cord from the electric outlet. Never allow the clips of the charger to touch each other. Clips may be energized and they may spark.
Attach clips to the battery and chassis, as indicated in sections 6 and 7.

FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN THE VEHICLE

WARNING: A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

Position AC and DC cords to reduce risk of damage by the hood, door, or moving engine part.
Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
Check the polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than NEGATIVE (NEG, N, –) post.
Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded to chassis (as in most vehicles), see (6.5). If a positive post is grounded to the chassis, see (6.6).
For a negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger to POSITIVE (POS, P, +) ungrounded post of the battery. Connect NEGATIVE (BLACK) clip 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.
For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the battery charger to the NEGATIVE (NEG, N, –) ungrounded post of the battery. Connect POSITIVE (RED) clip to vehicle chassis or engine block away from the 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.
When disconnecting the charger, turn the switch to off, disconnect AC cord, remove clip from the vehicle chassis, and then remove clip from the battery terminal.
See Calculating Charge Time for the length of charge information.

FOLLOW THESE STEPS WHEN THE BATTERY IS OUTSIDE THE VEHICLE

WARNING: A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

Check the polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger diameter than
NEGATIVE (NEG, N, –) post.
Attach at least a 24-inch-long 6-gauge (AWG) insulated battery cable to NEGATIVE (NEG, N, –) battery post.
Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) post of the battery.
Position yourself and the free end of the cable as far away from the battery as possible – then connect the NEGATIVE (BLACK) charger clip to free end of the cable.
Do not face battery when making the final connection.
When disconnecting the charger, always do so in reverse sequence of connecting procedure and break first connection while as far away from battery as practical.
A marine (boat) battery must be removed and charged onshore. To charge it on board requires equipment specially designed for marine use.

GROUNDING AND AC POWER CORD CONNECTIONS

This battery charger is for use on a nominal 120-volt circuit and has a grounded plug. The charger must be grounded, to reduce the risk of electric shock. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances. The plug pins must fit the receptacle (outlet). Do not use with an ungrounded system.
DANGER: Never alter the AC cord or plug provided – if it does not fit the outlet, have a properly grounded outlet installed by a qualified electrician. An improper connection can result in a risk of an electric shock or electrocution.
NOTE: Pursuant to Canadian Regulations, use of an adapter plug is not allowed in Canada. Use of an adapter plug in the United States is not recommended and should not be used.
USING AN EXTENSION CORD
The use of an extension cord is not recommended. If you must use an extension cord, follow these guidelines:
• Pins on plug of the extension cord must be the same number, size, and shape as those of plug-on charger.
• Ensure that the extension cord is properly wired and in good electrical condition.
• Wire size must be large enough for the AC ampere rating of charger, as specified:

CONTROL PANEL

CHARGE RATE SELECTOR SWITCH
Use the charge rate selector switch to select the charge rate or engine start setting.
Charge – For charging small and large batteries.
Boost – For quickly adding energy to a severely discharged or large capacity battery prior to Engine Start.
Engine Start – Provides additional amps for cranking an engine with a weak or run-down battery.
Always use in combination with a battery.
TIMER
The timer allows you to set a specified time for charging. After the timer expires, the charger stops charging your battery. The main function of the timer is to prevent overcharging while allowing battery time to obtain a satisfactory charge. Monitor the charger and battery. To properly set the timer, you must know the size of the battery (in ampere-hours) or reserve capacity (in minutes) and the state of charge. It is important that you determine the appropriate state of charge of your battery and set the
timer accordingly.
AMMETER
The Ammeter indicates the amount of current, measured in amps, that is being drawn by the battery. As a battery takes on a charge, it draws less current from the charger. Correspondingly, the meter will show less current being drawn by the battery. When the current stops decreasing, the battery is charged. The start area of the meter indicates a high rate of current being drawn from the charger. When cranking an engine, the meter needle will be at the extreme right side of the start area. The 2 amp charge rate may indicate some activity on the meter, although the meter does not have the resolution to display this low rate.

USING CHARGE MODE
Use for charging automotive, marine and deep-cycle batteries. Monitor the charging process and stop when the battery is fully charged. Not doing so may damage your battery and result in property damage or personal injury.
USING BOOST MODE
Use Boost mode for quickly adding energy to a severely discharged or large capacity battery prior to Engine Start. Monitor the boosting process.
USING THE ENGINE START FEATURE
Your battery charger can be used to jump-start your car if the battery is low. Follow all safety instructions and precautions for charging your battery. Wear complete eye protection and protective clothing.
WARNING: Using the Engine Start feature WITHOUT a battery installed in the vehicle could damage the vehicle’s electrical system.
NOTE: If you have charged the battery and it still will not start your car, do not use the Engine Start feature, or it could damage the vehicle’s electrical system. Has the battery been checked?

Set the timer to the OFF position.
With the charger unplugged from the AC outlet, connect the charger to the battery following the instructions are given in the Follow These Steps When Battery Is Installed In-Vehicle section.
Plug the charger’s AC power cord into the AC outlet.
With the charger plugged in and connected to the battery of the vehicle, set the Charge Rate selector switch to the Engine Start position.
Crank the engine until it starts or 5 seconds pass. If the engine does not start, wait 3 minutes before cranking again. This will recharge the battery.
NOTE: During extremely cold weather, or if the battery is under 2 volts, use Boost or Engine Start for 5 minutes before cranking the engine.
If the engine fails to start, use Boost or Engine Start for 5 more minutes before attempting to crank the engine again.
After the engine starts, move the timer to the OFF position and unplug the AC power cord before disconnecting the battery clamps from the vehicle.
Clean and store the charger in a dry location.
NOTE: If the engine does turn over but never starts, there is not a problem with the starting system; there is a problem somewhere else with the vehicle. STOP cranking the engine until the other problem has been diagnosed and corrected.

FAN OPERATION
It is normal for the fan to run while the timer is on. Keep the area near the charger clear of obstructions, to allow the fan to operate efficiently.

CALCULATING CHARGE TIME
When you know the percent of charge and the Amp-hour (Ah) rating of your battery, you can calculate the approximate time needed to bring your battery to a full charge.
Example: Amp hour rating = Reserve capacity + 16/2
NOTE: The Reserve Capacity can be obtained from the battery‘s specification sheet or the owner’s manual.
To calculate the time needed for a charge:

Find the percentage of charge needed.
Multiply the Amp-hour rating by the charge needed, and divide by the charge rate.
Multiply the results by 1.25 to find the total time needed, in hours, to bring the battery to full charge.
Add an additional hour for a deep-cycle battery.

Example:
Ah rating x % of charge needed x 1.25/Charger Amp setting = hrs of charge
100 (Ah rating) x .50 (charge needed) x 1.25 /20 (Charger Setting)= 3.125 hrs
100 x .50 x 1.25/20 = 3.125
You need to charge a 100 Ampere hour battery for a little more than 3 hrs at the 20 Amp charge rate, using this example.
Use the following table to determine the time it will take to bring a battery to full charge.
The times given are for batteries with a 50% charge prior to recharging.
CCA = Cold Cranking Amps Ah = Amp Hour
RC = Reserve Capacity NR = Not Recommended

Frequently Asked Questions

What is the difference between a “trickle charger” and a “smart charger”?

A trickle charger provides a constant current at a low voltage. A smart charger is designed to detect when the battery is fully charged and then switch to a float mode. A smart charger will not overcharge your battery.

What is the difference between a “smart” and an “intelligent” charger?

An intelligent charger has more sophisticated electronics, which allows it to perform additional functions, such as charging different types of batteries and charging at different rates depending on the condition of the battery. An intelligent charger may also be referred to as a “microprocessor controlled” or “microprocessor controlled advanced” charger.

How do I know if my battery needs to be charged?

If your battery has been in storage for more than three months, it should be recharged before use. If your vehicle has been sitting unused for more than three months, you should recharge the battery before attempting to start the engine. If your vehicle has been driven less than 1 mile (1.6 km) after being fully charged, recharge the battery before driving again. If you have just purchased a new battery, you should fully charge it before using it in your vehicle for the first time.

How do I charge my battery?

Read all instructions carefully before using this product. 1) Connect the output clips of the smart charger to the corresponding terminals on your battery (see diagram). Make sure that both clips make good contact with their respective terminals. 2) Plug the AC power cord into an AC outlet and switch on the power by pressing down on the rocker switch (see diagram). The red light will come on indicating that power is being supplied to the unit. The green light will come on when the unit enters into float mode monitoring your battery’s state of charge while maintaining it at full capacity (see diagram). The green light will remain lit as long as power is supplied to unit and will turn off when either of these conditions are not met (i.e., unit unplugged or switched off). The red light will blink during charging and remain solid when charging is complete. When charging is complete, remove AC power cord from wall outlet and unplug smart charger from AC outlet before disconnecting clips from terminals on car or other storage device’s battery (see diagram). Do not attempt to disconnect clips while red light is blinking or you may damage your smart charger or car’s electrical system. 3) To maintain proper care for your smart charger, always store it in a dry location when not in use and follow all instructions listed above for use of this product.

How do I know if my Schumacher battery charger is charging?

With the charger plugged in and connected to the battery of the vehicle, set the Charge Rate selector switch to the Engine Start position. Crank the engine until it starts or 5 seconds pass. If the engine does not start, wait 3 minutes before cranking again. This will recharge the battery.

How long does it take to fully charge Schumacher battery charger?

Charges in 6 to 8 hours. 2 Amp Trickle Charge – charges a small 12 volt battery in 2 to 12 hours. Back-lit, impact-resistant, color-coded meter for easy viewing day or night.

What does a blinking green light mean on a battery charger?

The blinking LED lights indicate different status of charge: Short green flash = less than 80% charged. Long green flash = more than 80% charged. Solid green light = 100% charged.

Can I start my car with a battery charger connected?

You may be able to… if the battery is at full charge. Best not try it. A battery charger delivers a few amperes at most. A properly charged battery delivers enough to turn over a starter motor or to melt a steel bar put between the poles

What does a red light on a battery charger mean?

If you see a red light on your charger, it typically means that the charger is working properly and that your battery is charging at the faster, “fast charge” rate. Of course, it’s always important to consult your charger’s manual to be sure.

How do you jump a car Schumacher battery charger?

And then read to red you see the light the red right there i’m not really sure what is that. But it’s on and then okay so that’s the back and that what he said is just turn this on the charge.

How do you see a Schumacher fully automatic battery charger?

When the battery is fully charged the green ready light will come on at this point the charger moves into maintained mode and can be left connected keeping the battery ready for use indefinitely.

Can you leave a battery charger on all the time?

Leaving an unattended trickle charger on for too long can overcharge the battery, which will shorten the lifespan of your battery and potentially damage it. It could also lead to overheating, fire, and explosion.
