3. Wear proper, non-absorbent gloves, complete eye
protection, and clothing protection. Avoid touching your
eyes and wiping your forehead while working near
batteries.

4. If battery acid contacts skin or clothing, wash
immediately with soap and water . If ac id enters your eye,
immediately flood it with running cold water for at least
twenty minutes and get medical attention immediately.

5. Never smoke or allow a spark or flame near the engine or
batteries.

6. Use extra caution to reduce the risk or droppi ng a metal
tool on the battery. It could spark or short circuit the
battery or other electrical parts and could cause an
explosion.

7. Remove all personal metal items, like rings, bracelets,
and watches when working with batteries. Batteries can
produce a short circuit current high enough to weld a ring
or metal bracelet or the like to the battery terminal,
causing a severe burn.

8. If you need to remove a battery, always remove the
negative terminal from the battery first for systems with
grounded negative. If it is grounded positive, remove the
positive terminal first. Make sure all loads connected to
the battery accessories are off so you don’t cause an arc.

9. Never charge a frozen battery.

PREPARING TO CHARGE

10. Make sure the area around the battery is well ventilated.

11. Make sure the voltage of the batteries matches the output
voltage of the battery charger.

12. Clean battery terminals. Be careful to keep corrosion
from coming into contact with your eyes and skin.

viii 975-0401-01-01

13. Study and follow all of the battery manufacturer's
specific precautions, such as removing or not removing
cell caps while charging, whether equalization is
acceptable for your battery, and recommended rates of
charge.

14. For flooded non-sealed batteries, add distilled water in
each cell until battery acid reaches the level specified by
the battery manufacturer. This helps to purge excessive
gas from cells. Do not overfill. For a battery without
removable cell caps, carefully follow manufacturer's
instructions.

BATTERY CHARGER LOCATION

15. Locate the Truecharge™ 2 Battery Charger unit away
from batteries in a well ventilated compartment.

16. Never place the Truecharge™ 2 Battery Charger unit
directly above batteries; gases from a battery will corrode
and damage the charger

1 Charging Output (%) LEDs

• The LEDs illuminate like a bar graph displaying the present total
output charge current as a percentage of the maximum rated
charge current. For example, unit model TC4012 has a maximum
rated charge current of 40 A so at 60% the charger’s current output
is 24 A. The numbers below the LEDs represent the percentage
values. See Figure 1-4 on page 1–10.

NOTE: When the maximum Charge Output current is limited via
the optional Remote panel, the LEDs will still display the total
charge output current as a percentage of the maximum rated
charge current and NOT as a percentage of the limited charge
current.

• One or two LEDs may flash intermittently in combination with a
solid Fault LED (indicating a fault) or with a flashing Fault LED
(indicating a warning). The icons above the LEDs represent the
various types of fault and warning conditions. See Figure 1-4 on
page 1–10.

2 Fault LED

The LED may illuminate a solid light (indicating a fault) or flash
intermittently (indicating a warning) in combination with flashing
Charging Output (%) LEDs. See Table 1-1, “Fault and Warning
Indicators” on page 1–11 for details.

3 Charger Status LEDs

Displays the current status of the charger.

• Ready - a solid light indicates batteries are fully charged and the

Select buttons.

The Fault LED works in conjunction with the Charging
Current (%) LEDs. The icons at the top row above the
Charging Current (%) LEDs represent the various types of
fault and warning conditions. For example, a temperature
warning is represented by a thermometer icon.

The Charging Current (%) LEDs will normally illuminate as
a solid progress bar when they are indicating the amount of
output charging current. If any of the LEDs start to flash
intermittently at the same time that the Fault LED is either
solid or flashing, a fault or warning condition is indicated.
