The lead-acid
replacement is here.
Drop-in sodium-ion cells validated for 12V, 24V and 48V automotive systems – with longer cycle life, broader temperature range, and zero thermal runaway.
10x the cycle life. Class-9 logistics. Sovereign supply.
Altris sodium-ion shifts the operational and supply-chain math.
| Capability | Lead-Acid | Altris Sodium-Ion |
|---|---|---|
| Cycle Life | 200-400 cycles | >4,000 cycles |
| Low-Temp Performance | Sub-optimal below 0C | Operates to -40C |
| Safety | H2 off-gassing risk | Best in class. EUCAR 3 |
| Shipping Classification | Class 8 Dangerous Goods | Non-Dangerous Goods |
| Raw Material Risk | Lead, regulated | Iron / Sodium, abundant |
| European Supply Chain | Partial | Up to 100% |
Application
Validated for real-world environments.
The Altris P-Series has been validated in a 12V-48V system architecture – the dominant configuration for low-voltage applications. Integration support and BMS guidance are available from our engineering team and system partners.
