HEALTH HAZARD DATA 
Under normal conditions of use, the battery is hermetically sealed. 
Ingestion: Swallowing a battery can be harmful. 
Contents of an open battery can cause serious chemical burns of mouth, esophagus, 
and gastrointestinal tract. If battery or open battery is ingested, do not induce vomiting 
or give food or drink. Seek medical attention immediately.   
Inhalation: Contents of an open battery can cause respiratory irritation. Provide fresh 
air and seek medical attention. 
Skin Absorption: Mercury can be absorbed through intact skin causing symptoms 
similar to those of ingestion. 
Skin Contact: Contents of an open battery can cause skin irritation and/or chemical 
burns. Remove contaminated clothing and wash skin with soap and water. If a 
chemical burn occurs or if irritation persists, seek medical attention. 
Eye Contact: Contents of an open battery can cause severe irritation and chemical 
burns. Immediately flush eyes thoroughly with water for at least 15 minutes, lifting 
upper and lower lids, until no evidence of the chemical remains. Seek medical 
attention. 
PRECAUTIONS FOR SAFE HANDLING AND USE 
Storage: Store in a cool, well ventilated area. Elevated temperatures can result 
in shortened battery life. 
Mechanical Containment: Batteries normally evolve hydrogen which, when 
combined with oxygen from the air, can produce a combustible or explosive 
mixture   
unless vented. If such a mixture is present, short circuits, high temperature, or 
static sparks can cause an ignition. 
Do not obstruct safety release vents on batteries. Encapsulation (potting) of 
batteries will not allow cell venting and can cause high pressure rupture. 
Handling: Accidental short circuit for a few seconds will not seriously affect the 
battery. Prolonged short circuit will cause the battery to lose energy, and can 
cause the safety release vent to open. Sources of short circuits include jumbled 
batteries in bulk containers, metal jewelry, metal covered tables or metal belts 
used for assembly of batteries into devices. 
Charging: This battery is manufactured in a charged state. It is not designed for 
recharging. Recharging can cause battery leakage or, in some cases, high 
pressure rupture. Inadvertent charging can occur if a battery is installed 
backwards.
