Hyundai GR8 Technical Service Bulletin

Technical Service Bulletin
SUBJECT:
This TSB supersedes TSB 14-EE-002 to include additional information in the "Important
section" and "Service Procedure section".
Description: This bulletin describes operation of the GR8 for battery related repair work. The GR8 is
a state of the art tool that checks battery health and then performs a reliable intelligent safe charge,
which can quickly restore some batteries to good condition. For example, a battery may be fully
revived within 1.5 hours if it has not been in a discharged state for an extended period of time.

IMPORTANT
 GR8 Battery Test clamps or Charger clamps must be connected directly onto the
battery posts. Do not connect to the jumper terminals in the engine compartment.
 The correct battery type selection, either "Flooded" or "AGM", must be selected
during GR8 Battery Testing and Charging to ensure correct results.
 Charging with an incorrect battery type selection may damage and shorten the life
of the battery.
 Always check the battery specification label affixed on top of the battery before
working on the battery and be sure to select the appropriate battery type.
 Always enter the "SAE CCA" and RC value printed on the battery specification label
for the GR8 battery CCA and RC rating.
 The replacement battery must be the same type of battery originally installed from
the factory.
