Product Highlights for B2B Buyers
- Highest Capacity in EVE’s Li-SOCl₂ Range: At 19,000mAh, the ER34615 delivers the most energy of any standard cylindrical cell in EVE’s primary battery portfolio — ideal for devices that need years or even decades of runtime without battery replacement.
- Massive Energy Density: The Li-SOCl₂ chemistry provides energy density far exceeding alkaline or standard lithium primary cells, enabling compact device designs even in power-hungry industrial applications.
- Ultra-Stable Discharge Curve: Voltage remains exceptionally flat across the majority of discharge life — critical for precision sensors, data loggers, and communication modules that are sensitive to voltage fluctuation.
- Extreme Temperature Tolerance: Operates reliably from -55°C to +85°C, making the ER34615 suitable for arctic outdoor monitoring, desert solar installations, industrial furnace proximity sensors, and everything in between.
- 10-Year Shelf Life: A self-discharge rate of ≤1% per year means the ER34615 retains its charge during long warehouse storage periods and pre-deployment staging — reducing waste and inventory risk for distributors.
- Glass-to-Metal Hermetic Seal: Superior sealing technology prevents electrolyte leakage even in high-vibration or high-humidity environments, ensuring long-term field reliability.
- Drop-In ER+SPC Compatibility: The ER34615 is the primary cell used in EVE’s ER34615+SPC hybrid solutions, pairing it with a supercapacitor for high-pulse-current applications such as NB-IoT and LoRa wireless transmission.
- Internationally Certified: Complies with CE, RoHS, UN38.3 (transport approved), IEC60086, and UL standards — simplifying customs clearance and regulatory approval in global markets.
