Sodium-Ion Starting Battery

Utilizing advanced polyanion sodium-ion chemistry, our Na+ batteries maintain over 60% capacity even at -40°C. This ensures consistent high Cold Cranking Amps (CCA) for immediate ignition in polar climates without the need for internal heaters or auxiliary power.

Our sodium-ion cells can be safely stored at zero voltage for up to 6 months without permanent capacity loss. This makes them the perfect choice for seasonal vehicles like motorcycles, snowmobiles, or classic cars that may sit idle for months.

With a design life exceeding 10 years, the Na+ series outlasts Lead-Acid by a decade. It eliminates the hassle and cost of frequent replacements, delivering a maintenance-free experience that pays for itself within the first few years.

The high-rate discharge and charge performance allow for massive power delivery in short bursts. The fast-charge capability ensures that even a short 15-minute drive is enough to replenish the battery's charge after a cold start.

Every battery is equipped with a Smart BMS (Battery Management System) that monitors voltage, current, and temperature in real-time. It provides multi-layer protection against overcharging, short-circuits, and deep discharge, ensuring high-performance power delivery.

Designed according to standard BCI group sizes, CTECHI Na+ batteries are direct "plug-and-play" replacements for existing lead-acid units. No modifications to the vehicle's charging system or mounting brackets are required.
