ENERGIZER 3V LITHIUM COIN
PRIMARY USES
1. Reliable Power for Medical Diagnostic and Monitoring Devices
Primary Use: Provides stable 3V DC power for a wide range of medical devices including glucometers, digital thermometers, heart rate monitors, pulse oximeters, and other portable diagnostic equipment requiring reliable, long-lasting coin cell power .
How it helps: For the endocrinologist and primary care physician, ensuring that portable diagnostic devices function accurately is essential for chronic disease management. The Energizer 3V lithium coin cell battery delivers a nominal voltage of 3.0V across various sizes including CR1616 (55 mAh), CR1620, CR2025 (163 mAh), and CR2032 (240 mAh) . Its compact dimensions allow integration into small, handheld medical devices. For the patient managing diabetes with a glucometer or monitoring cardiovascular health with a heart rate monitor, this means consistent, reliable power for daily health monitoring.
2. Ingestion Burn Protection and Advanced Child Safety Features
Primary Use: Features the world’s only coin lithium battery with Ingestion Burn Protection that prevents burning if swallowed, along with Colour Alert technology that dyes the mouth blue seconds after contact with saliva to help alert caregivers to act fast, plus a non-toxic bitter coating to help discourage ingestion .
How it helps: For the paediatrician and emergency medicine physician, button battery ingestion is a medical emergency that can cause severe esophageal burns and death within two hours. Energizer’s 3-in-1 Child Shield provides a superior number of safety features: Ingestion Burn Protection prevents burning if swallowed; Colour Alert technology creates an immediate visual cue for caregivers; and the bitter coating helps deter children from swallowing . The secure, child-resistant packaging requires scissors to open, preventing child access . For parents and caregivers, these safety features provide critical minutes to seek medical attention before permanent injury occurs.
3. High Energy Density for Extended Device Operation
Primary Use: Lithium manganese dioxide (Li/MnO₂) chemistry provides high energy density and stable voltage output throughout the discharge cycle, making these batteries ideal for continuous-use medical devices such as wearable monitors and remote patient monitoring systems.
How it helps: For the biomedical engineer and clinical equipment manager, devices requiring continuous or frequent operation need batteries that maintain consistent voltage. The lithium chemistry delivers a flat discharge curve, ensuring devices receive stable power for their entire service life. The CR2032 variant provides 240 mAh capacity, offering extended runtime for power-dependent medical equipment . For the patient using a continuous glucose monitor or wearable heart monitor, this means fewer device interruptions and more reliable data collection.
4. Extended Shelf Life for Medical Emergency Preparedness
Primary Use: Provides up to 10-12 years of shelf life at 21°C, making these batteries ideal for emergency medical kits, backup monitoring equipment, disaster preparedness supplies, and home healthcare “go-bags” where infrequent replacement and immediate readiness are critical .
How it helps: For the public health official and home health nurse, medical devices and emergency equipment stored for extended periods must function when called upon. Energizer 3V lithium coin cells hold power for up to 12 years in storage, significantly reducing inventory management burden . The leakage-resistant construction protects sensitive medical equipment from corrosive damage during extended storage. For the patient and caregiver, this means confidence that backup devices will function when needed.
5. Wide Operating Temperature Range for Diverse Clinical Environments
Primary Use: Operates reliably across a wide temperature spectrum from -30°C to 60°C (-22°F to 140°F), making these batteries suitable for medical devices used in various clinical settings, outdoor emergency response, and home healthcare environments .
How it helps: For the emergency physician and field medic, medical equipment may need to operate in challenging environmental conditions. The lithium chemistry maintains performance across extreme temperatures, ensuring devices function whether stored in a cold ambulance (-30°C) or used in a warm clinical setting (60°C) . For the home healthcare patient, this means devices remain reliable regardless of seasonal temperature variations in the home.
SECONDARY USES
1. Powering remote keyless entry systems for medical fleet vehicles: For healthcare facilities with vehicle fleets, CR2025 and CR2032 batteries power keyless entry remotes for medical transport vehicles, delivery vans, and emergency response cars used by home health nurses and medical couriers .
2. Operation of electronic organizers and clinical scheduling devices: Powers portable electronic organizers and scheduling devices used by medical administrators and clinical staff for patient appointment management.
3. Powering fitness trackers and pedometers in rehabilitation programmes: For patients in physical therapy and cardiac rehabilitation, CR2016 and CR2032 batteries power activity trackers, pedometers, and wellness monitors used to track recovery progress .
4. Operation of digital watches and timers in clinical settings: Powers digital watches, stopwatches, and timing devices used by medical professionals for procedure timing, medication administration tracking, and laboratory work .
5. Laboratory and research equipment: Powers timers, calculators, and counting devices used in medical laboratories and research settings where precision and reliability are required .
