How it helps: For the emergency medicine physician and disaster response coordinator, standard alkaline batteries experience sharp capacity loss at low temperatures, while the lithium-iron disulfide chemistry maintains excellent performance across the entire temperature spectrum. The L92 maintains usable voltage down to -40°C, while alkaline batteries fail at these temperatures . For the paramedic responding to a winter emergency or the military medic operating in a desert environment, this means critical medical equipment remains operational when environmental conditions would otherwise disable battery-powered devices.
3. Intrinsically Safe Certification for Hazardous Medical Environments
Primary Use: Certified for intrinsically safe use in hazardous locations with ATEX certification (Ex ia IIC Ga) and UL 913 certification (Class 1, Division 1, Groups A-D, T4) for explosive atmospheres, making these batteries suitable for medical equipment used in oxygen-rich environments, operating rooms with flammable anaesthetics, and emergency response in industrial settings .
How it helps: For the hospital safety officer and biomedical engineer, medical equipment used in operating rooms, burn units with oxygen therapy, or emergency response in chemical plants must meet strict safety standards to prevent ignition of flammable gases. The Energizer L92 lithium AAA holds ATEX certification (Baseefa14ATEX0107U, Ex ia IIC Ga) for use in Group IIC explosive atmospheres (including hydrogen and acetylene) with T4 temperature classification . For configurations of 1-2 AAA cells, the certification covers Group IIC, T4 from -40°C to +60°C. For 3-4 AAA cells, UL certification covers Groups C and D, T4 . For the clinician working in high-risk environments, this allows the use of battery-powered medical devices where standard batteries would pose an ignition hazard.
4. Twenty-Year Shelf Life for Medical Emergency Preparedness
Primary Use: Provides up to 20 years of shelf life at 21°C, making these batteries the ideal power source for emergency medical kits, backup monitoring equipment, disaster preparedness supplies, and medical “go-bags” where infrequent replacement and immediate readiness are critical .
How it helps: For the public health official and emergency preparedness coordinator, medical equipment stored in emergency kits may sit untouched for years before deployment. The Energizer Ultimate Lithium AAA retains significant capacity after 20 years of storage at 21°C . The leak-proof construction protects sensitive medical equipment from corrosive damage during extended storage . For the first responder and relief worker, this means diagnostic tools and monitoring equipment function when reaching patients in disaster zones, eliminating preventable battery failure as a variable in emergency care.
5. Lightweight Design for Portable and Wearable Medical Devices
Primary Use: At just 7.6 grams per cell (approximately one-third the weight of standard alkaline AAA batteries), these batteries are ideal for portable and wearable medical devices where weight reduction improves patient comfort and device portability .
How it helps: For the product designer and rehabilitation physician, wearable medical devices such as continuous monitors and portable diagnostic tools must balance power requirements with patient comfort. The L92 weighs 7.6 grams compared to approximately 11.5 grams for a standard alkaline AAA, saving significant weight per cell .

2. FIRST AID MEASURES

  • Ingestion: Do not induce vomiting. Do not give food or drink. Seek immediate medical attention. Call the National Battery Ingestion Hotline at 800-498-8666 (US) or 202-625-3333 (collect) day or night for advice and follow-up. Provide the medical team with the identification number from the battery's package if possible.
  • Eye contact (battery leakage/rupture): Contents of an open battery can cause severe eye irritation and corneal burns. If battery ruptures and contents contact eyes, rinse immediately with plenty of lukewarm water for a minimum of 15 minutes. Get immediate medical attention.
  • Skin contact (battery leakage/rupture): Contents of an open battery can cause skin irritation and chemical burns. Wash skin with soap and water for at least 15 minutes. If irritation persists or burns are present, seek medical attention.
  • Inhalation (battery leakage/rupture): Contents of an open battery can cause respiratory irritation. Move to fresh air. If symptoms persist, seek medical attention.
  • Swallowing a battery (no rupture): If a battery is swallowed intact but not ruptured, do not induce vomiting. Seek immediate medical evaluation for potential esophageal obstruction or battery ingestion protocols. Do not wait for symptoms to develop.

3. FIRE FIGHTING MEASURES

  • Flammability: Lithium-iron disulfide batteries are combustible. In case of fire where lithium batteries are present, flood area with water or smother with a Class D fire extinguisher appropriate for lithium metal (e.g., Lith-X).
  • Extinguishing Media: Water may not extinguish burning batteries but will cool adjacent batteries and control fire spread. Burning batteries will burn themselves out. Virtually all fires involving lithium batteries can be controlled by flooding with water. However, battery contents react with water to form hydrogen gas; in confined spaces, hydrogen can form an explosive mixture, making smothering agents recommended.
  • Maximum Surface Temperature under Short-Circuit Test: 110-112°C (-40°C ≤ Ta ≤ +60°C) .
  • Hazardous Combustion Products: Burning lithium-iron disulfide batteries produce toxic and corrosive lithium hydroxide fumes and sulfur dioxide gas.
  • Fire Response: Emergency responders should wear self-contained breathing apparatus (SCBA) and full protective gear. For small fires, use appropriate extinguisher. For large fires, evacuate area.
