IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

  • Read all instructions, warning, and cautions printed on the battery charger, battery and vehicle or equipment using battery.
  • DO NOT expose charger to rain or snow.
  • Use of an attachment not recommended or sold by the battery charger manufacturer may result in a risk of fire, electric shock, or injury to persons.
  • To reduce risk of damage to electric plug and cord, pull by plug rather than cord when disconnecting charger.
  • An extension cord should not be used unless absolutely necessary.
  • Use of an improper extension cord could result in a risk of fire and electric shock. If an extension cord must be used, make sure:
    • The pins on plug of extension cord are the same number, size, and shape as those of plug on charger.
    • The extension cord is properly wired and in good electrical condition.
    • The wire size is large enough for the AC ampere rating of the charger, as specified in the chart on the following page.
  • DO NOT operate charger with damaged cord or plug—replace the cord or plug immediately.
  • DO NOT operate charger if it has received a sharp blow, been dropped, or otherwise damaged in any way—take it to a qualified serviceman.
  • DO NOT disassemble the charger. Take it to a qualified service professional if service or repair is required. Incorrect assembly may result in fire or electric shock.
  • To reduce risk of electric shock, unplug charger from outlet before attempting any maintenance or cleaning. Turning off controls will not reduce this risk.

WARNING—RISK OF EXPLOSIVE GASES

  • WORKING IN THE 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 risk of battery explosion, follow these instructions and those published by battery manufacturer and manufacturer of any equipment you intend to use in the vicinity of the battery. Review cautionary markings on these products and on engine.

PERSONAL SAFETY INSTRUCTIONS

  • Consider having someone close 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 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 vicinity of battery or engine.
  • Take extra precautions to avoid dropping a metal tool onto the battery. It may spark or create a short circuit that can 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 a LEAD-ACID battery only. It is not intended to supply power to a low voltage electrical system other than in a starter-motor application. Do not use 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 it is necessary to remove battery from vehicle to charge, always remove grounded terminal from battery first. Make sure all accessories in the vehicle are off so as not to cause an arc.
  • Be sure area around battery is well ventilated while 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 level specified by battery manufacturer. Do not overfill. For a battery without removable cell caps, such as valve-regulated lead-acid batteries, carefully follow manufacturer’s recharging instructions.
  • Study all battery manufacturer’s specific precautions while charging and follow 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 correct voltage. If charger has adjustable charge rate, charge battery initially at lowest rate.

CHARGER LOCATION

  • Locate charger as far away from battery as DC cables pemit.
  • 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 electrolyte specific gravity or filling battery. Do not operate charger in a closed-in area or restrict ventiation in any way.
  • Do not set a battery on top of charger.

DC CONNECTION PRECAUTIONS

  • Connect and disconnect DC output clips only after removing AC cord from electric outlet. Never allow clips to touch each other.
  • Attach clips to battery and chassis as indicated in the Connecting Your Battery section.

CONNECTING YOUR BATTERY

  • Attach at least a 24″ (61 cm) 6-gauge (AWG) insulated battery cable to NEGATIVE (NEG, N, -) battery post.
  • Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) post of battery.
  • 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.
  • When disconnecting 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 on shore. To charge it on board requires equipment specially designed for marine use.

CONTROLS AND INDICATORS

  1. Digital Display
    During charging, the digital display will alternate between Volts (V), Amperage (A) and Battery State of Charge (%). It can also display Fault Codes if a charging error is detected.
    Volts—Actual charging voltage will be displayed. Charging voltage can reach up to 14.4 V—this is normal and required to effectively charge a 12-volt battery.
    Amps—Actual charging amperage will be displayed. While you may select 2 A, 8 A, or 15 A charge modes, these are maximum currents and the battery charger will reduce actual current delivered to the battery based on feedback from the battery and other factors.
    Stage of Charge—The approximate battery state of charge is displayed. A reading of “LO” indicates that the battery is below 50% state of charge. Above 50%, the percentage will display in 10% increments between 60 to 90% capacity. Once the battery is fully charged, the display will read “100%”.
    NOTE: About 30 minutes after reaching full charge, the battery charger will enter a power-saving mode and the digital display will turn off.
    Fault Codes—The charger will continuously monitor charge progress and collect feedback from the battery during charging. In the event an abnormal condition is detected, charging will stop and a fault code (e.g., ”F01”) may be displayed. (See ”Troubleshooting/Fault Codes” for possible causes and solutions.)
  2. Fault/Error Indicator
    This LED will light up if the charger detects a problem and can not proceed with charging.
    • Amber (solid)—No battery detected. Check to ensure that clamp connections to the battery posts are clean and solid. If connections are good, the battery is severely discharged (<1.5 V) and may be unsafe to charge. The battery should be tested or replaced. (NOTE: “888” will also appear on the digital display)
    • Red (blinking)—A fault has been triggered and charging has been aborted. Check the digital display for a Fault Code and see “Troubleshooting/Fault Codes” for possible causes and solutions.
    • Red (solid)—Reverse polarity has been detected. Reverse clamp connections.
  3. Charge Status Indicator
    A blinking LED indicates the battery is charging. A solid LED indicates charging is complete and battery charger has entered the Maintain stage. (See “UNDERSTANDING the MULTI-STAGE CHARGING PROCESS” section.)
  4. Battery Type
    There are 3 battery types to choose from. Pressing the button repeatedly will cycle through each of the battery types. See below for an overview of each type.
    NOTE: The battery charger will retain the last selected mode in memory. In the event AC power is disrupted (e.g., power failure), the charger will re-start in the last selected mode once power is restored.
    Battery Type Explanation

CHARGING YOUR BATTERY

  1. Connect the charger clamps to the battery (following the steps outlined in “Connecting Your Battery”).
  2. Plug the charger AC plug into an electrical outlet.
    NOTE: If a fault or error is detected, the LED will illuminate (see Charge Status Indicators).
  3. Press the button to select battery type.
  4. Press the MODE button to select a charging program.
    NOTE: If no selection is made within 5-seconds, the charger will default to the last selection in memory and automatically begin charging.
  5. our battery is fully charged when the indicator turns solid green and the display reads “100%”.
  6. Stop charging at any time by disconnecting the charger AC plug from the electrical outlet.

Using Reconditioning

If a lead-acid battery is left sitting in a low state of charge, or is deeply discharged, or is never given the opportunity to fully charge, it can suffer capacity loss due to sulphation and/or stratification. Such a battery can appear to have a normal open circuit voltage and yet it will have a noticeable drop in performance. Using Reconditioning mode may help to reverse the affects of sulphation and stratification, restoring lost battery capacity.
To maximize battery life and performance, Recondition your battery once per year or after deep discharges. For best results, take the battery through a normal full charge cycle before using this mode. A Reconditioning charge can take up to 4 hours to complete.

CAUTION: USE THIS MODE WITH CARE. RECONDITIONING USES A HIGH CHARGING VOLTAGE AND MAY CAUSE WATER LOSS IN THE BATTERY. IT IS BEST SUITED FOR WET (FLOODED) BATTERIES WITH REMOVABLE VENT CAPS WHICH ALLOWS FOR WATER LEVELS TO BE TOPPED UP. RECONDITIONING IS NOT RECOMMENDED FOR AGM OR GEL BATTERIES. TO MINIMUM RISK OF HIGH VOLTAGE TO SENSITIVE ELECTRONICS, DISCONNECT THE BATTERY FROM THE VEHICLE (OR ANY OTHER EQUIPMENT) WHEN USING THIS MODE.

UNDERSTANDING FACTORS THAT AFFECT CHARGING TIME

The time it takes to fully recharge a battery depends on several factors including:

  1. Battery Depth of Discharge
    The greater the depth of discharge, the longer it will take to fully charge a battery. For example, a battery discharged to a level of 50% will take about twice as long to fully charge than a battery discharged only 25%.
  2. Battery Size
    If charged at the same current, a larger (higher capacity) battery will require more time to fully charge than a smaller (lower capacity) battery. This difference can be overcome by charging larger batteries at a higher current.
  3. Battery Age and Condition
    As a battery ages, its internal resistance will increase, impacting its ability to accept current. This effect is particularly noticeable in batteries that have not been well-maintained over their life.
  4. Battery Type
    Some battery chemistries, such as AGM and gel, have lower internal resistance which means they can accept charge better without generating damaging heat. Such batteries can charge up to 2 times faster than traditional wet battery types.
  5. Charge Rate
    The charge rate is measured in amperes (A). A battery charged at a lower rate will take longer to fully charge than a battery charged at a higher rate. This does not mean that one should always charge a battery at the highest ampere available as this can cause overheating and premature battery failure. A battery should be charged at a rate appropriate for its size—a good, safe rule of thumb is about
    th1/10 it’s Amp-hour capacity (e.g., 100 Ah battery x1/10=10 A).
  6. Cold Temperature
    Cold temperatures slow down the chemical reaction that takes place inside a battery when it is charging. Charging a battery at a cold temperature can greatly increase the amount of time required to charge the battery. Ideal charging temperature is between 10 to 25ºC (50 to 77ºF).

UNDERSTANDING THE MULTI-STAGE CHARGING PROCESS

STAGE 1 DESULPHATION*
Pulses of voltage and current help recover sulphated or deeply discharged batteries.
STAGE 2 SOFT START*
Gently introduces current to condition deeply discharged batteries and prevent overheating that could damage the battery.
STAGE 3 BULK
Charging with maximum current to bring the battery to about 80% capacity.
STAGE 4 ABSORPTION
Charging with constant voltage while reducing current to safely bring the battery to 100% capacity. This stage is key to maximizing battery performance and battery life.
STAGE 5 ANALYZE
Tests if battery is holding charge.
STAGE 6 MAINTENANCE
Monitors battery voltage and provides top-up charging when necessary to keep battery fully charged.
