and those published by the battery manufacturer and the
manufacturer of the equipment in which the battery is installed.
Precautions When Working With Batteries
1. Have someone within range of your voice or close enough to come
to your aid when you work near a lead-acid battery.
2. Have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing, or eyes.
Important Safety Information
xi
3. Wear complete eye protection and clothing protection. Avoid
touching your eyes while working near batteries.
4. If battery acid contacts skin or clothing, wash immediately with
soap and water. If acid enters your eye, immediately flood it with
running cold water for at least twenty minutes and get medical
attention immediately.

Introduction
Chapter 1, “Introduction” introduces and
describes features of the Truecharge+ multistage
battery chargers.
Introduction
1–2
Truecharge+
Features
Truecharge+ is an advanced battery charger designed specifically for high
performance, deep-cycle lead-acid batteries. It is smaller and lighter than
many other chargers and can be installed or stored in small compartments.
It has AC to DC isolation, a surge protector, and many other safety
features which reduce potential shock and fire hazards.
20/40 Amp Continuous Rating
Truecharge 20+ delivers a 20 amp charging current and the
Truecharge 40+ delivers 40 amps for approximately 75% of the charging
cycle. The chargers only reduce the charging current below these rated
levels when the battery is approaching full charge or when there may be
overheating in high ambient temperatures. Because it delivers rated
current over most of the charge cycle, Truecharge+ charges your batteries
faster than many other chargers with a higher rating.
Many other chargers only deliver their rated charging current for a short
initial part of the charge cycle.
Simultaneous Three-Battery Bank Charging
Truecharge+ has three separate DC positive terminals to allow charging
of three separate batteries (or battery banks). The total current into the
batteries is a maximum of either 20 amperes or 40 amperes, depending on
the model, which is divided amongst the batteries according to their state
of discharge.
Wide Voltage Range Operation
Truecharge+ maintains the correct charging voltage for your battery when
the AC line voltage drops as low as 90 VAC, or rises as high as 135 VAC.
A surge protector in Truecharge+ protects it from surges and spikes on the
AC power line.
Note: The three outputs are not independently voltage regulated so it
is important to avoid systems with mixed types of batteries.
Truecharge+ Features
1–3
Selector Switches
Truecharge+ has selector switches for charge mode, battery type, and
battery temperature setting.
Charge mode The charge-mode switch allows you to select three-step charge, two-step
charge or 13.5 volt fixed output modes. Refer to Appendix B, “Battery
Charging” for an explanation of the charging algorithms.
Battery type The battery-type switch allows you to set the Truecharge+ for the
charging characteristics of flooded, AGM, and gel batteries.
Temperature The battery temperature switch allows you to set charging characteristics
based on the battery temperature. By setting the switches correctly before
you begin charging your battery, you will be ensuring that it receives the
best possible charge.
Extensive Protection Features
Truecharge+ provides the following protection features:
Opening of the internal output fuse if a battery is accidentally
connected with reversed polarity
Fuse opening or electronic shutdown if there is a short circuit on the
output of the Truecharge+
Built-in protection against accidental connection to a higher battery
voltage, up to 24 VDC
Unit shutdown if it becomes overheated because of inadequate
ventilation or a high ambient temperature
Unit shutdown if the battery gets too hot (with battery temperature
sensor only)
Isolated Design
The DC battery charging circuits of Truecharge+ are galvanically isolated
by a transformer from the AC power circuits. This feature reduces the risk
of electric shock and helps to prevent corrosion problems in marine
applications.
Introduction
1–4
Fixed Voltage Mode
The fixed voltage mode setting is meant to be used as a power supply or
battery eliminator. It is not meant for charging batteries. The battery type,
battery temperature, and equalize switches are all ignored in fixed voltage
mode. The remote battery temperature sensor does not compensate the
voltage, but the battery over-temperature shutdown is still active.
Optional Accessories
Battery
Temperature
Sensor
The remote Battery Temperature Sensor (BTS) automatically adjusts the
charge according to the temperature of one of the batteries. With a BTS
installed, the unit provides a more accurate temperature-compensated
charge for the battery to which the sensor is attached.
Remote panel The remote panel allows you to monitor the charging progress of two
batteries or battery banks, the total charge current, and charger status from
a convenient location.
Indicator Lights and Settings on the Front Panel
This section describes the parts of the front panel of the Truecharge 20+.

3 The recessed Equalize button is triggered manually to enter or leave
the equalization mode.
4 The Charger Mode switch from which you can select a three-stage or
two-stage charge or a 13.5 volt power supply mode to power 12 volt
loads when you don’t have a battery.
5 The battery selection switch for choosing flooded, gel or AGM
batteries.
6 The battery-temperature switch for choosing the battery temperature
for the charge. Temperature settings compensate the output voltage
for the battery temperature.
Note that a battery temperature sensor overrides the temperature
settings on the front panel.
Introduction
1–6
How Truecharge+ Works
Truecharge+ changes the alternating current (AC) supply from the utility
to the controlled low-voltage, direct current (DC) required to charge the
battery by using high-frequency, switched-mode power conversion
circuits. The high-frequency power conversion method is similar to that
used in power supplies for computers and other electronic equipment. It
results in a significantly smaller and lighter charger than other power
conversion methods allow.
The controlled DC output is fed to three isolations diodes, one for each
battery bank. These diodes isolate the batteries from each other and
prevent current flow from one battery to the others.

Installing
Truecharge+
Chapter 2, “Installing Truecharge+” lists the
materials you receive, provides site
recommendations for installing Truecharge+, and
provides the materials and procedures for its
installation.
The chapter also makes reference to the
installation codes that may be applicable in your
application, for example, the US National
Electrical Code (NEC, NFPA 70), the Canadian
