Introduction Your Xantrex Truecharge 10 is an advanced battery charger designed specifically for today’s high performance deep-cycle lead-acid batteries. It provides charging performance that simple marine and automotive chargers are unable to provide. The Truecharge 10 is designed to recharge 12 volt lead-acid batteries with capacities from 25 amp hours to 200 amp hours.
charging current for a short initial part of the charge cycle. Charging current decreases rapidly (“tapers off”) as the battery charges. Because it delivers rated current over most of the charge cycle, your Truecharge 10 will charge your batteries faster than many other chargers rated at 20 amperes or more. Wide Voltage Range Operation Now you can give your battery a top-quality charge even when your AC power isn’t top quality.
Theory of Operation High Frequency Power Converter The Truecharge 10 uses modern high frequency switching power circuits to convert the alternating current from the utility line to the low voltage direct current required to charge the battery. The circuits are similar to those used in power supplies for computers and other modern electronic equipment. The alternating current from the utility line is first rectified by diodes to produce a high voltage direct current.
Three-Step Charging Process Modern lead-acid batteries will last longer and charge faster if they are charged in a particular sequence known as a three-step charge. The Truecharge 10 implements the three-step charging process. In the first step, known as the bulk charge, the Truecharge 10 delivers its rated current (10 A) until the battery voltage approaches its gassing voltage—typically around 14.4 volts. The bulk charge step restores about 75% of the battery's charge.
conditions are met: • A battery is connected • The battery is connected with proper polarity • The battery voltage is between 5 volts and 13 volts The Truecharge 10 will not act as a battery eliminator or power supply. It must be connected to a battery to operate. Once the Truecharge 10 detects proper connection to a battery, it begins the three-step charging cycle.
The first two conditions ensure that the Truecharge 10 keeps your battery “topped up” if it is left permanently connected. The last two conditions ensure that the Truecharge 10 starts in a predictable fashion after you disconnect the battery or the AC power. WARNING! To reduce the risk of sparking and damage to your Truecharge 10, always disconnect AC power from your Truecharge 10 before connecting or disconnecting the battery or batteries. Important Safety Instructions SAVE THESE INSTRUCTIONS.
before attempting any maintenance or cleaning. 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 READ THIS MANUAL AND FOLLOW THE INSTRUCTIONS EXACTLY. • To reduce the risk of battery explosion, follow these instructions and those published by the battery manufacturer and the manufacturer of the equipment in which the battery is installed.
this battery charger to charge nickel-cadmium (Ni-Cd), nickel-metal hydride (Ni-MH), lithium (Li) and dry cell batteries commonly used with home appliances and electronic equipment. These batteries may burst and cause injury to persons and damage to property. The charger is not intended to supply power to an extra-low voltage electrical system without a battery. • NEVER charge a frozen battery. Charging a battery when its temperature is below 32 °F (0 °C) is inefficient and ineffective.
DC Connection Precautions • Connect DC output clips only after the AC cord is connected to the electrical outlet and the charger indicator lights turn on. The charger has an anti-sparking feature that only functions properly if the charger is on. • Attach clips to battery posts and twist or rock back and forth several times to make a good connection. This tends to keep the clips from slipping off the terminals and helps to reduce risk of sparking.
CAUTION! To reduce risk of fire, do not cover or obstruct the ventilation openings. Do not install the Truecharge 10 in a zeroclearance compartment. Overheating may result. WARNING: This equipment contains components that may produce arcs or sparks. To prevent fire or explosion, do not install in compartments containing batteries or flammable materials or in locations that require ignition-protected equipment.
Battery Charging Safety Charging a battery when it is installed in an engine compartment To reduce the risk of a spark near the battery: 1) Position AC and DC cords to reduce risk of damage by access doors, hood, or moving engine parts. 2) Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons. 3) Ensure that the compartment has been ventilated to remove flammable or explosive gasses such as battery gasses and fuel vapor.
Charging a battery when it is installed outside the engine compartment To reduce the risk of a spark near the battery: 1) Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post usually has a larger diameter than the NEGATIVE (NEG, N, –) post. 2) Connect the charger to AC power. When the lights on the charger begin to blink, connect the POSITIVE (RED) charger clip to the positive (POS, P, +) post of the battery.
Operating Instructions Charge Cycle The Truecharge 10 can charge all 12 volt lead-acid batteries including sealed, maintenance-free, and gel types. It is best suited for batteries with capacities between 25 ampere hours and 200 ampere hours. (battery sizes from U1 to 4D). Charging is automatic. The READY status indicator on the Truecharge 10 will light when charging is complete.
3) Set the BATTERY TEMPERATURE selector switch for the temperature of your battery. If your battery temperature is below 50 °F, (10 °C), set the switch to COLD. If your battery temperature is between 50 °F (10 °C) and 80 °F (27 °C), set the switch to HOT. 4) Attach the supplied AC power cord and connect the Truecharge 10 to AC power (90 VAC to 130 VAC 50/60 Hz. The indicator lights on the Truecharge 10 will begin blinking in sequence. The Truecharge 10 may take up to one minute to begin charging.
Charging Times Charging time will depend on the capacity of your battery and on how deeply it is discharged. The following equation gives an approximate charging time: Charging time = CAP × DOD 850 where: Charging Time = Battery recharge time in hours CAP = Battery capacity in ampere hours DOD = Battery depth of discharge in % (A fully discharged battery has 100% DOD) Example: The battery is a Group 27 size with a rated capacity of 80 ampere-hours. It is 80% discharged (i.e. DOD = 80).
Troubleshooting Problem Possible Cause Solution Indicator lights are all off when charger is connected to an AC receptacle. No power at AC receptacle. Defective cord. Open fuse in charger. Indicator lights continue to scroll when the charger is connected to a battery and AC Check polarity and quality of battery Charger does not detect battery for one of following connection.
