Warning: Never water a cold battery. Only water a battery during the degassing process of an
equalization charge, or immediately after an equalization charge. Watering a cold battery will
result in overflowing of battery acid which will reduce battery life and damage the truck and/or
battery.
This document provides guidelines for charging, discharging, and maintaining the Deka D-series industrial traction
battery used in the Eagle eTT and MTT tow tractors. These instructions assume the most common options package
and may differ from your truck.
This recommended battery maintenance procedure is not intended to replace the battery manufacturer's recommen-­‐‑
dations and procedures. Where a conflict may exist between this document and the battery manufacturer's recom-­‐‑
mendations and procedures, the battery manufacturer's requirements shall be followed.
Charging Procedures for Opportunity Charge Batteries:
1) Charging the battery is as simple as plugging the charger cord into the quick charge port on the side of the truck.
For an opportunity charge or a full charge, nothing else is required. The charger will display the charge process
and the "Charge Complete" LED on the charger will illuminate when the charge cycle has been completed. For
a general idea of charge times, please see the Estimated Charge Times table on the second page of this Guide.
2) The battery may be opportunity charged as required on a daily basis. To stop the charge process, disconnect the
charger from the truck, or press the stop button on the charger.
3) In order to complete a full charge, leave the charger connected until the "Charge Complete" LED on the charger
illuminates. Note: The charger is programmed to only charge the battery higher than 80% once per day so to not
cause damage to the battery.
4) The battery must be "equalize" charged once per week, or every 80 hours of use. The charger will automatically
schedule an equalization charge if it has been 10 days since the last equalization. The charger will blink the
"Equalize" LED to let you know that it will perform an equalization charge at the end of the current charge cy-­‐‑
cle. To manually perform an equalization charge, press the "Equalize" button during charging. The LED will
begin blinking to confirm that an equalization has been scheduled. Note: An Equalization charge should not be
performed more than 1 time per week so to not cause damage to the battery.
5) Add water to the battery weekly as part of the equalization charge process. Add water while on charge during
degassing (the equalization portion of the charge), or as soon as possible after the charge cycle. The filling sys-
tem should only be connected long enough for the cells to fill (usually 1 to 3 minutes). When the flow indicator
stops spinning, or nearly stops, the cells are full and the quick-disconnect coupler should be disconnected.
CAUTION: The plugs continue to drop a very small amount of water even when the floats are up and overfill-
ing could result if the supply line is left connected.
