Altech Batteries' SNC Technology Delivers Record-Breaking Reliability with Just 0.6% Failure Rate
Altech Batteries Limited (ASX: ATC) has released compelling service data that positions its Altech Batteries' sodium-nickel-chloride technology as a game-changer in the energy storage sector. After more than 15 years of real-world deployment across South Africa's harsh telecommunication and UPS infrastructure, SNC batteries have demonstrated an exceptional failure rate of just **0.6-1.5%**—dramatically outperforming traditional battery technologies.
The data reveals that SNC batteries routinely achieve service lives exceeding 15-20 years with minimal maintenance requirements, operating reliably in temperatures above 50°C and enduring constant power interruptions. This performance track record validates Altech's strategic positioning in the rapidly expanding European pipeline and hydrogen control infrastructure markets.
"It's great to see real service-life data confirming the reliability and consistency of SNC battery technology. These results back up our long-held understanding of how well the batteries perform under harsh conditions, including high temperatures and frequent power disruptions." — Iggy Tan, Managing Director
SNC Batteries Outperform Competition with Superior Reliability Metrics
The field performance data from South Africa presents a stark contrast to industry-standard failure rates across competing battery technologies. While lithium-ion systems typically fail at rates of 3-5%, and lead-acid batteries suffer failure rates of 8-12%, Altech Batteries' sodium-nickel-chloride technology maintains its exceptionally low 0.6-1.5% failure rate even under extreme operating conditions.
| Battery Technology | Service Life (Years) | Field Failure Rate | Maintenance Requirements | Temperature Range (°C) |
|---|---|---|---|---|
| SNC (Sodium-Nickel-Chloride) | 15-20 | 0.6-1.5% | None | -40 to +60 |
| Lithium-Ion | 10-15 | 3-5% | Periodic BMS checks | 0 to +40 |
| Lead-Acid | 3-5 | 8-12% | Frequent/equalisation | 0 to +40 |
| Nickel-Cadmium | 10-15 | 2-4% | Routine | -20 to +50 |
Key performance differentiators include:
• Zero explosion or fire risk (fireproof and explosion-proof design)
• 100% recyclable with 50% lower carbon footprint compared to lithium-ion
• ATEX-suitable for explosive environments
• Lowest total cost of ownership over 15-year operational periods
Understanding Sodium-Nickel-Chloride Battery Technology
Sodium-nickel-chloride batteries represent a breakthrough in solid-state energy storage technology that addresses critical limitations of conventional battery systems. The technology utilises a beta-alumina ceramic electrolyte that manages chemical reactions between molten sodium and nickel chloride within a fully sealed, solid-state architecture.
The ceramic construction eliminates common battery failure modes including dendrite formation, electrolyte degradation, and thermal runaway. Unlike lithium-ion batteries that require complex cooling systems and frequent monitoring, SNC batteries operate maintenance-free for decades.
Furthermore, this translates to significantly lower operational costs and higher system reliability—critical factors for industrial and infrastructure applications where downtime costs can exceed thousands of dollars per hour.
Why This Technology Creates Investment Value
Altech Batteries' sodium-nickel-chloride technology offers several technical advantages that create compelling investment opportunities:
• Self-healing capability: Micro-cracks in ceramic automatically seal due to molten sodium flow
• Individual cell independence: System continues operating even if single cells fail
• No active cooling required: Operates efficiently across extreme temperature ranges
• Immune to over-discharge damage: Can remain idle for months without capacity loss
How SNC Batteries Achieve Extended Service Life
The exceptional longevity of Altech Batteries' sodium-nickel-chloride technology stems from its unique construction. The beta-alumina ceramic electrolyte contains no flammable liquids, produces no venting gases, and creates no corrosion pathways.
Internal chemical reactions between molten sodium and nickel chloride remain stable across thousands of cycles. In addition, the ceramic construction prevents electrode dendrite formation and electrolyte degradation that plague lithium-ion systems.
The technology demonstrates immunity to over-discharge damage and can remain idle for extended periods without capacity loss. Consequently, this creates exceptional value for applications requiring long-term reliability.

Technological Redundancy Provides System Reliability
The exceptional reliability of Altech Batteries' sodium-nickel-chloride technology extends beyond individual cell performance. Each cell operates within a beta-alumina solid electrolyte tube that allows sodium ions to pass while blocking electrons.
If micro-fractures develop in the ceramic, the molten sodium seeps into cracks and forms ionic bridges that maintain conductivity. Battery modules contain multiple cells connected in series or parallel configurations.
If one cell's resistance increases, others compensate to ensure steady voltage and reliable overall performance. This redundancy ensures uninterrupted system operation even under challenging conditions.
South African Field Experience Validates Technology
SNC batteries have operated across South Africa since the early 2010s, supporting telecommunication towers, utility substations, and industrial control systems. The technology operates reliably in temperatures regularly exceeding 50°C and withstands constant power interruptions.
Units installed in the mid-2000s continue operating today without maintenance or electrolyte replacement. Field data collected by AMPower demonstrates the remarkably low failure rate of 0.6% to 1.5%.
With no active cooling requirements and minimal servicing needs, field evidence confirms SNC batteries are well-suited to remote or high-temperature environments where traditional batteries fail. Therefore, this proven track record creates significant competitive advantages.
