Warning
  For safe and proper use of the battery, please read the enclosed directions and warning labels on the battery cover.
   
Danger
  The battery emits hydrogen gases. In particular, large amounts are emitted during the latter phase of battery charging. Placing metal tools on the (+)/(-) terminals of the battery or using the battery in highly flammable, wet and poorly ventilated areas can lead to explosion and/or fire.
   
Danger
  The battery fluid contains dilute sulfuric acid. Do not tilt the battery or exert undue necessary force. When checking the battery, always wear rubber gloves and protective eye covering and be careful not to spill any of the battery fluid. Contact with the fluid can cause blindness and burns. If the fluid comes into contact with the eyes, skin or clothes, immediately rinse the affected area with large amounts of water. In particular, if the fluid gets into the eyes, seek medical treatment by a physician or optometrist right away. If the fluid enters the oral cavity or is swallowed, repeatedly gargle with water, drink large amounts of water and then seek medical treatment right away.
   
Danger
  The battery contains battery fluid and should be kept out of the reach of persons (children) who are unfamiliar with the risks and dangers involved. The battery fluid can cause blindness and severe burns.

   O
Replace battery
3. Internal short
circuit
Voltage greater than 12.3V and drops of greater than 2V during testing when hydrometer is green
 O  
Replace battery (Excludes old batteries. If hydrometer is black, recharge battery and test.)
Voltage less than 12V and hydrometer is green
 O  
Replace battery (Dead batteries is due to user error.)
Maturation of grids and missing active material due to long-term battery use
   O
Replace battery
4. Malfunctioning hydrometer
Voltage greater than 12.3V and shaking the hydrometer continues to read black
 O  
Replace hydrometer parts
Hydrometer continues to read black even after recharging
    
Replace hydrometer parts (Contamination of foreign substances)
5. Leakage on terminals
Discoloration and leakage in between the terminals and the cover
   O
Replace hydrometer parts
Discoloration and leakage due to ‘buckling’ or damage from excessive outside force
 O O
Replace hydrometer parts (Contamination of foreign substances)
6.‘Buckling’/damage of terminals
Damage due to excessive outside force (i.e. use of a hammer during installation)
   O
Replace battery
Damage due to external short circuit (overheating, spark)
   O
Replace battery
White corrosion due to sulfuric acid
   O
Clean and grease terminals
7. Reversed indication of polarity on cover
Indicated polarity on cover is reverse of the actual polarity
-Should read: Cathode (+): Thick diameterAnode (-): Narrow diameter
O  
Replace battery
8. Leakage on case floor due to faulty emission
Faulty emission through pin hole on case floor
 O  
Replace battery (Excludes damages)
9. Simple discharge
Voltage falls below 12.3V leading to improper charging, cars parked for long periods of time, interior lights left on
   O
*Recharging
*Inspect charging device
10. Severe discharge
Voltage falls below 11.78V, leaving the battery in a discharged state for long periods of time makes material on grids inactive
   O
*Can be recharged, but will give poor performance*If cannot be recharged, replace battery
11. Irregular reduction in battery acid
Reduction in battery acid due to problems with charging device (hydrometer: white)
   O
Inspect charging device, replace battery
Overcharging of discharged battery
   O
Replace battery
