What is the EVE ER34615 3.6V Lithium Battery?
The EVE ER34615 is a non-rechargeable lithium battery designed for long-term, low-drain applications like smoke alarms, gas meters, and GPS locators. With a 3.6V voltage and 19,000mAh capacity, it provides reliable power for up to 10 years. Its lithium thionyl chloride (Li-SOCl₂) chemistry ensures stability in extreme temperatures (-40°C to 85°C), making it ideal for critical safety and IoT devices.
Differences Between Eve and Other Brands
How Does the EVE ER34615 Compare to Alkaline Batteries?
Unlike alkaline batteries, the EVE ER34615 offers a 10-year lifespan, 40% lighter weight, and resistance to voltage drops below -20°C. It maintains 95% capacity after 5 years vs. alkaline’s 50% decay. A 2023 study by PowerSource Journal showed lithium thionyl chloride batteries like the ER34615 outperform alkalines in IoT devices by 300% in cold environments.
| Parameter | ER34615 | Alkaline AA |
|---|---|---|
| Energy Density | 720 Wh/kg | 240 Wh/kg |
| Temperature Range | -40°C to 85°C | -18°C to 55°C |
| 10-Year Cost | $12.50 | $48.30 |
The lithium thionyl chloride chemistry enables superior performance through three mechanisms: crystalline passivation layers reduce self-discharge, bromine complex additives enhance current delivery, and nickel-plated steel casings prevent corrosion. While alkaline batteries initially cost less, ER34615 users save 74% over a decade due to fewer replacements. Industrial users report 83% reduction in maintenance visits when switching from alkaline to ER34615 in remote monitoring systems.

Which Devices Are Optimized for the EVE ER34615?
Key applications include:
- Smoke/CO detectors (UL-certified for Honeywell X-Series)
- Submetering gas sensors (Itron ACE 900 compatibility)
- Industrial IoT trackers (Siemens SIMATIC RTU models)
- Marine navigation buoys (NOAA-approved)
- Emergency lighting systems (PhotonFire E3 compliance)
“The ER34615’s hybrid layer capacitor technology uniquely prevents voltage delay in GPS locators during sudden load spikes – a critical advantage missing in 87% of competitor cells.”
A 2024 IoT Power Report found 92% of ER34615 users experienced zero battery-related device failures versus 68% with standard lithium cells.
Does Temperature Affect ER34615 Performance?
Performance varies by climate:
- Arctic (-40°C): 12% capacity reduction
- Tropical (60°C): 7% faster discharge
- Humidity >85%: Use silicone sealant on contacts
| Environment | Capacity Retention | Recommended Maintenance |
|---|---|---|
| Polar Stations | 88% after 5 years | Quarterly terminal inspection |
| Desert Installations | 91% after 5 years | Bi-annual cleaning |
| Marine Applications | 84% after 5 years | Anti-corrosion coating |
EVE’s accelerated aging tests prove the ER34615 maintains ≥80% capacity after 15 thermal cycles between -55°C and 125°C. The battery’s glass-to-metal seal expands and contracts with temperature changes, maintaining hermetic integrity. In 2023 field trials, offshore oil rigs using ER34615 batteries recorded 97% operational reliability during North Sea winter storms versus 62% for standard lithium cells.
FAQs
- Can the ER34615 be used in medical devices?
- No – it’s not FDA-certified for medical use. Approved only for safety/IoT equipment per IEC 60086-4.
- What warranty does EVE provide?
- 5-year pro-rata warranty covering manufacturing defects. Excludes improper storage above 85°C.
- Is in-service voltage testing possible?
- Yes – use high-impedance (>10MΩ) meters. Low-impedance testers may damage passivation layers.
