Product Details
Product Overview & High-Power Design
The GEB ER34615M 3.6V 13Ah D-Size Spiral High-Power Primary LiSOCl2 Battery (with Solder Tabs) is engineered specifically for applications demanding heavy continuous current and high-amperage RF transmission pulses without voltage drop. Unlike standard bobbin cells, the ER34615M incorporates a wound spiral electrode architecture that expands active electrochemical surface area, delivering up to 2000mA (2.0A) continuous discharge and massive 3000mA–4000mA (3A–4A) peak pulse currents. Built with a hermetic glass-to-metal seal and an integrated safety pressure vent, this 3.6V 13,000mAh D-size cell operates reliably across -55°C to +85°C. Typical applications include LoRaWAN, NB-IoT cellular transmitters, asset GPS trackers, emergency beacons, automated pipeline shutoff valves, and high-decibel alarm sirens. Warning: Primary lithium cell; strictly do not charge.

Equipment Compatibility & Fit Check
The ER34615M is an exceptional high-current power source. Verify the following parameters prior to installation:
- Current Demand Verification (Spiral vs. Bobbin): The ER34615M is purpose-built for heavy loads (>200mA continuous, or >500mA pulses). If your device only requires microampere background monitoring with infrequent small pulses, choose our higher-capacity 19Ah ER34615 Bobbin Cell for longer calendar life.
- Pre-welded Solder Tabs & Wire Harnesses: Due to high discharge currents (up to 4A), standard consumer battery spring clips can cause contact resistance and voltage drops. We strongly recommend our pre-welded pure nickel solder tabs or heavy-gauge flying leads.
- Compartment Thermal Clearance: When continuously discharging at >1.0A, allow adequate heat dissipation clearance around the steel canister.
- Strict Anti-Charging Verification: Confirm that all external power interfaces include Schottky isolation diodes to prevent reverse current from reaching the primary lithium cell.
First-Party Engineering & Quality Control Evidence
Precision Spiral Winding
Automated precision winding tension control ensures tight, uniform contact between the high-surface carbon cathode and lithium foil, reducing AC internal resistance to ≤45 mΩ.
Integrated Pressure Relief Vent
Because spiral cells support high discharge currents, each ER34615M is equipped with a patented calibrated safety vent mechanism to safely relieve pressure in case of accidental external shorting.
Low Voltage Delay Guarantee
The wound electrode structure minimizes passivation thickness and provides massive active surface area, ensuring instantaneous voltage recovery (>3.0V) upon heavy 3A pulse application.
Engineering Judgment & Boundary Conditions
✓ When ER34615M Is an Ideal Fit:
- LoRaWAN, NB-IoT, LTE Cat-M1, and GSM transmitters with recurrent 1A–3A RF transmission bursts.
- Asset tracking beacons, container GPS tracking, and oceanographic acoustic transponders.
- Electric valve actuators, automated pipeline shutoff valves, and high-power alarm sirens.
- Harsh cold-climate deployments (-40°C) requiring high instantaneous pulse current delivery.
✗ When ER34615M Is NOT Recommended:
- Pure micro-drain static monitoring (<50µA) where 15–20 year life is required; choose ER34615 Bobbin (19Ah).
- Applications where continuous discharge exceeds 2.5A without active thermal dissipation.
- Rechargeable systems or consumer devices lacking reverse voltage protection.
- Compact battery bays limited to AA size; see our ER14505 AA Cell.

Frequently Asked Questions
Q: What does the “M” in ER34615M signify?
A: In international primary lithium battery nomenclature, “M” designates a spiral-wound high-power electrode design. It signifies that the cell is built for high continuous and pulse discharge currents (up to 2A continuous, 4A pulse), unlike standard bobbin cells which are limited to low currents (≤150mA–200mA).
Q: Can the ER34615M directly power a NB-IoT or LoRa module without a supercapacitor?
A: Yes, in most applications. The ER34615M can easily deliver 1A–3A pulses with its low internal resistance (≤45 mΩ), maintaining a voltage above 3.0V. This eliminates the need and expense of adding an auxiliary pulse capacitor (SPC) for many IoT designs.
Q: Why is the capacity of ER34615M (13Ah) lower than ER34615 (19Ah)?
A: The spiral wound construction requires additional current collector foils and separator layers inside the same D-size volume, which slightly reduces the space available for active chemical materials. The trade-off is 10× greater discharge power in exchange for ~30% lower total capacity.

Equipment Compatibility & Engineering Fit Check
Before deploying GEB ER34615M 3.6V 13Ah D-Size Spiral High-Power Primary LiSOCl2 Battery (with Tabs), verify these verified electrical and mechanical boundary requirements:
Operational Boundary Conditions
✔ Recommended Fit & Use Cases:
- Utility meters, IoT telemetry nodes, and remote tracking devices requiring 3.6V long-life primary power.
- Sub-zero or high-temperature deployments (-55°C to +85°C) where rechargeable chemistries fail.
- Autonomous sensors demanding microamp standby combined with scheduled RF pulse bursts.
⚠ Operational Constraints & Limits:
- Do not recharge: Connecting a primary Li-SOCl2 cell to external chargers risks severe internal pressure venting or rupture.
- Avoid dead-shorting terminals during installation; account for voltage delay (passivation) after prolonged storage.
- Ensure connector polarity and pin assignment match system schematics prior to initial power-up.
