Energizer Lithium AAA Battery

ENERGIZER LITHIUM AAA BATTERY

PRIMARY USES

1. Longest-Lasting Power for High-Tech Medical Devices
Primary Use: Provides stable 1.5V DC power with exceptional runtime for high-drain medical devices including continuous glucose monitors (CGMs), insulin pumps, pulse oximeters, portable patient monitors, and handheld diagnostic equipment where extended battery life is critical for patient care .
How it helps: For the endocrinologist and biomedical engineer, high-tech medical devices draw significant current and rapidly deplete standard alkaline batteries, leading to frequent battery changes and potential treatment interruptions. The Energizer Ultimate Lithium AAA is advertised as the world’s longest-lasting AAA battery for high-tech devices . It provides a rated capacity of 1250 mAh with a maximum continuous discharge of 1.5 Amps (per single battery) and pulse discharge capability of 2.0 Amps (2 seconds on / 8 seconds off) . For the patient managing diabetes with a CGM or insulin pump, this means fewer device interruptions, more reliable overnight monitoring, and reduced risk of treatment disruption due to battery failure.

2. Extreme Temperature Operation for Emergency Medical Equipment in Field Conditions
Primary Use: Operates reliably in extreme temperatures from -40°C to 60°C (-40°F to 140°F), making it suitable for emergency medical kits, search and rescue equipment, outdoor first responder gear, and medical devices used in harsh environmental conditions where standard alkaline batteries fail .
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 . For the patient wearing a continuous glucose monitor or using a handheld diagnostic device, this means lighter, less intrusive devices that are more comfortable for all-day use, improving compliance and quality of life.

SECONDARY USES

1. Powering high-drain portable diagnostic equipment in field medicine: For mobile health clinics, community health worker programs, and humanitarian medical missions, these batteries power portable handheld ECGs, digital thermometers with backlit displays, pulse oximeters, and diagnostic equipment requiring high current draw, enabling care delivery in remote areas without reliable mains electricity.

2. Operation of therapeutic devices requiring sustained high-current output: Powers motorised medical devices including portable TENS units for pain management, handheld therapeutic massagers, and other high-drain therapeutic equipment where extended runtime between battery changes is desired for patient convenience.

3. Powering medical telemetry and remote patient monitoring systems: For home healthcare and remote patient monitoring, these batteries power wireless transmitters, wearable monitors, and telemetry devices where long life, reliability, and leak-proof construction are essential for continuous data transmission and device protection.

4. Emergency backup for critical care transport equipment: For ambulance services and medical evacuation teams, these batteries provide reliable backup power for portable monitors, handheld diagnostic devices, and communication equipment during patient transport, with extreme temperature tolerance ensuring operation in any environment.

5. Specialised laboratory and field research equipment: For medical researchers and field epidemiologists, these batteries power portable pH meters, conductivity meters, handheld spectrophotometers, and diagnostic testing equipment used in remote locations or during prolonged field studies where battery changes are impractical.
