Product Details
Product Overview & Application Scope
The GEB ER14505 3.6V 2700mAh AA-Size Primary Lithium Thionyl Chloride (Li-SOCl2) Battery is an industrial-grade bobbin-construction primary cell engineered specifically for ultra-long-life, low-drain utility metering and IoT applications. Featuring a high operating voltage of 3.6V, an exceptionally low self-discharge rate of < 1% per year at 25°C, and a robust glass-to-metal hermetic seal, this non-rechargeable cell delivers dependable 10 to 15-year maintenance-free service lifespans across an extreme temperature range of -55°C to +85°C. Typical applications include smart water meters, gas meters, AMR/AMI remote meter reading, heat cost allocators, and wireless alarm sensors. Warning: This is a primary lithium cell and must strictly NOT be charged.

Equipment Compatibility & Fit Check
The ER14505 battery is the international AA-size standard for smart meters and sensors. Before ordering replacement cells or custom batches, verify the following engineering parameters:
- Compartment Cavity Clearance: Ensure internal compartment supports Ø 14.7mm × H 51.0mm minimum clearance including terminal tabs and insulation shrink.
- Operating Current Profile: This Bobbin cell is optimized for microampere background monitoring (<50µA) with periodic pulses (≤150mA). If your device uses cellular NB-IoT/LTE-M with sustained pulses >500mA, consider our ER34615M Spiral High-Power Cell or request an integrated ER14505 + SPC1520 hybrid capacitor pack.
- PCB Footprint & Lead Spacing: Verify pin pitch (e.g. 5.0mm / 10.0mm 2-pin radial or 3-pin polarizing layout) to match your circuit board holes.
- Strict Charging Prohibitions: Ensure your host device has zero reverse-charging leakage current (≤0.5µA blocking diode circuit recommended).
First-Party Engineering & Quality Control Evidence
Hermetic Glass-to-Metal Seal
We utilize true compression glass-to-metal (GTMS) insulation seals with automated helium mass-spectrometer leak testing (≤ 1×10⁻⁸ mbar·L/s) to ensure zero electrolyte leakage over 15 years.
Automated Laser Spot Welding
Nickel and tinned copper terminal tabs are welded via precision computer-controlled fiber lasers with destructive tensile pull-strength testing (≥ 5.0 kgf) per production batch.
Depassivation Activation SOP
To combat passivation voltage delay after extended warehouse storage, every batch can be conditioned with calibrated electrical loads before packaging for immediate field readiness.
Engineering Judgment & Boundary Conditions
✓ When ER14505 Is an Ideal Fit:
- Smart water meters, gas meters, and heat metering devices requiring 10+ year lifespans.
- Low-power IoT sensors operating on periodic sleep/wake cycles with background draw <20µA.
- Extreme environmental monitoring stations (-40°C arctic or +70°C pipeline environments).
- Compact medical telemetry and asset tracking beacons where volume and weight (19g) are critical.
✗ When ER14505 Is NOT Recommended:
- Continuous load currents exceeding 50mA (causes rapid polarization and severe capacity reduction).
- Direct unbuffered cellular LTE-M / 2G / 3G transmissions requiring 1A–2A pulse peaks without a hybrid capacitor.
- Systems with rechargeable charging circuits (primary lithium cells will burst if charged).
- Applications where D-size capacity is needed; consider our higher-capacity ER34615 19Ah Cell.

Frequently Asked Questions
Q: Why does an ER14505 battery experience a brief voltage dip upon initial load?
A: This is due to the natural lithium chloride (LiCl) passivation film on the anode, which preserves the battery during storage. Once loaded, the film rapidly dissolves, and the voltage recovers to normal operating levels within milliseconds. For heavy immediate pulse demands, we provide depassivated stock or hybrid capacitor modules.
Q: Can I use the ER14505 to replace a standard alkaline AA or rechargeable 14500 battery?
A: No. Alkaline AA batteries output 1.5V, and rechargeable 14500 Li-ion cells output 3.7V (rechargeable). The ER14505 produces 3.6V primary non-rechargeable power. Inserting an ER14505 into a 1.5V consumer device will likely burn out the electronics, and charging it could cause a hazardous rupture.
Q: What is the difference between Bobbin ER14505 and Spiral ER14505M?
A: The Bobbin ER14505 offers higher capacity (2700mAh) and lowest self-discharge for micro-current devices. The Spiral ER14505M has wound electrodes offering higher continuous/pulse currents (up to 500mA) but with slightly lower capacity (~2000mAh) and higher self-discharge. For most metering applications, Bobbin ER14505 is the industry standard.

Equipment Compatibility & Engineering Fit Check
Before deploying GEB ER14505 3.6V 2700mAh AA-Size Primary Lithium Thionyl Chloride (LiSOCl2) Battery, 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 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 to external chargers risks thermal runaway or internal pressure venting.
- Avoid dead-shorting terminals during installation; maintain cell insulation integrity.
- Ensure connector polarity and pin assignment match system schematics prior to initial power-up.
