Request for Inspection of Lead-Acid Batteries

June 25th, 2024

Thank you for your continued patronage of our lead-acid battery products.

In recent years, accidents have occurred with lead-acid batteries manufactured by some overseas manufacturers, which are believed to be caused by the generation of hydrogen sulfide, a toxic gas, due to a combination of certain conditions, such as use in high-temperature environments, use with less than the specified amount of electrolyte, and overcharging. It is said that these accidents could have been prevented if the lead-acid batteries had been inspected and diagnosed beforehand and appropriate measures had been taken for their deteriorated condition or if they had been used correctly.

In order to prevent similar accidents, please take the following precautions when using our products.

  • Before installing lead-acid batteries, be sure to read the instruction manual carefully and do not use the batteries for purposes other than those specified. Improper handling of batteries in poorly ventilated areas can cause poisoning due to hydrogen sulfide emitted from the storage batteries, which may result in death.
  • Lead-acid batteries with a bulk exhaust structure installed in the cabin must be used with the exhaust hose properly attached and the generated gases vented from the vehicle. Incorrect installation of the exhaust hose can cause hydrogen sulfide poisoning, which may result in death.
  • When replacing lead-acid batteries, replace them with the correct storage batteries specified for the vehicle or equipment in which they are installed. Use of incorrect storage batteries can cause hydrogen sulfide poisoning, which may result in death.
  • Check the electrolyte level regularly. If the electrolyte level drops abnormally, stop using the battery. Continued use of the battery with less than the specified amount of electrolyte may cause hydrogen sulfide to be generated. It may also cause damage to the battery.
  • If you notice any unusual odor (such as rotten egg smell), stop using the battery immediately and move to a well-ventilated area away from the vehicle, equipment, or battery. Hydrogen sulfide emitted from the battery can cause poisoning and death.

We appreciate your understanding and cooperation.
