Innovative battery chemistry
Sodium-ion technology uses sodium ions to store and release energy. A different chemical approach from the traditional lead-acid battery.

The technology
A different approach
to energy storage.
Sodium-ion uses sodium ions instead of traditional lead-acid chemistry. GreenPower combines the engineering view with commercial practice, so partners can offer the technology with confidence.
Focused on practice
We investigate what the technology can mean for professional use, with the vehicle, the charging system and the everyday application at the centre.
Your Network. Our Expertise. Worldwide Opportunity.
GreenPower brings technology, product sourcing, manufacturing-partner relationships, technical documentation and international supply expertise; resellers and distributors contribute customer relationships, local knowledge and sales channels. Together we introduce sodium-ion starter batteries worldwide.
Why sodium-ion
The next generation of starter battery.
Sodium-ion combines reliable starting with a chemistry that contains no lithium. A premium addition to AGM, EFB and lead-acid batteries for partners who want to move ahead.
Hot and cold
Built for hot and cold climates: indicative ambient conditions from −40 °C to +40 °C. Cold starting down to −40 °C is manufacturer-stated for selected H-series models; fitment and performance are checked per model.
Long service life
Estimated service life of 10–15 years depending on use, and 3,000–4,000+ cycles as a model-specific supplier statement.
Integrated BMS
A battery management system monitors charging and discharging and protects the cells.
IP65
IP65 ingress protection according to the supplier.
Lighter
Lighter than comparable lead-acid batteries, where documented per model.
No lithium
Sodium is widely available. That spreads raw-material supply risk — without claiming lithium is running out.
A premium alternative, not a universal replacement
Sodium-ion complements AGM, EFB and lead-acid. Suitability is decided per vehicle and application.
A price level around 30% above traditional batteries is an illustrative indication; actual pricing depends on final sourcing and volumes.
Warranty: provisionally 36 months (3 years), subject to supplier confirmation.
Critical minerals outlook 2035
Tomorrow’s supply questions, today’s portfolio decision.
The International Energy Agency’s Global Critical Minerals Outlook 2026 projects potential mine-supply gaps by 2035 for lithium and copper despite new projects, with the projected copper gap revised to around 25% and lithium still facing a shortfall. These are projections, not a statement that resources run out.
Sodium is widely available. A sodium-ion starter battery range is a premium strategic diversification alongside lead-acid, AGM and EFB — not a universal replacement.

UN38.3 transport tests (samples)
- T.1 Altitude simulation Pass
- T.2 Thermal test Pass
- T.3 Vibration Pass
- T.4 Shock Pass
- T.5 External short circuit Pass
- T.6 Impact / crush Pass
- T.7 Overcharge Pass
- T.8 Forced discharge N/A
UN38.3 is a transport safety test — not a certification of product performance or vehicle suitability. The thermal test (T.2) includes exposure to −40 °C and +72 °C; this is not an operating temperature range.
Transport classification (sea freight)
According to the classification report: UN3551, Class 9, when shipped standalone as ‘sodium ion batteries’ by sea, 360 Wh; packaging to PG II performance standard. The report is only valid within 2026. Packaging and ADR/IMDG/IATA conditions are reviewed separately per route and configuration.
According to the manufacturer (H-series)
Manufacturer/supplier statements, separate from the UN38.3 transport tests above. Values can differ per model; model-specific documents on request.
| Starting current / CCA | Varies by model; printed on each battery and its packaging |
|---|---|
| Starting / discharge | Down to −40 °C |
| Normal charging | 0 °C to +80 °C; below 0 °C the BMS limits charging to 0.2C and blocks fast charging (minimum temperature not independently confirmed) |
| Estimated service life | Approx. 10–15 years, depending on use (supplier statement) |
| Cycles | 3,000–4,000+, supplier reference value per model |
| Ingress protection | IP65 (supplier statement) |
| CE and OEM documentation | On request, per model; no general CE or OEM approval claimed |
Manufacturer statements have not been independently tested by GreenPower.
Other models (H6–H9, motorcycle, truck, jump start): preliminary reference specifications only, still in verification.
Specific applications, such as automatic door systems, are handled as custom enquiries; no suitability for safety-critical use is claimed.
Model-specific datasheets and reports: on request, where available.
