Product Advantages

  • Exceptional Cycle Life – Delivering over 3,000 cycles at 1C 70% DOD, our sodium‑ion battery offers 3 to 6 times longer service life than conventional lead‑acid batteries, dramatically reducing long‑term replacement costs and delivering outstanding cost‑effectiveness.
  • Unmatched Cold‑Weather Performance – Rated for -20°C to 60°C wide‑temperature operation, it retains over 80% capacity even at -20°C and delivers high cold cranking amps (CCA) for instant, reliable ignition in freezing conditions – outperforming both lead‑acid and lithium‑ion batteries in extreme cold.
  • Inherently Safe & Thermally Stable – Sodium‑ion chemistry is less flammable than lithium‑ion, with a higher thermal runaway onset temperature (over 220°C) and virtually zero risk of fire or explosion. It prevents thermal runaway even under high temperatures or overcharging – giving you total peace of mind.
  • Maintenance‑Free & Eco‑Friendly – Fully sealed design means no topping up, no acid leaks, no corrosion. Sodium is abundantly available, low‑cost, and easier to extract than lithium, making our battery a more sustainable, environmentally friendly choice.
  • Perfect for Start‑Stop & Daily Driving – Engineered for the demanding cycles of start‑stop systems, it handles frequent engine restarts with ease. With superb rate performance and low self‑discharge, it ensures consistent power delivery for modern vehicles
