IV. Product Advantages
Reliable Quality and Long-Term Assurance
Original HAKADI sodium-ion cells: Ensures authenticity and avoids performance issues caused by counterfeit or low-quality cells.
Pre-shipment testing: Each cell undergoes voltage, resistance, and appearance checks before shipment, guaranteeing basic quality stability.
5-year warranty: Free replacement for manufacturing defects, providing users with long-term after-sales protection and reducing purchase risks.
Long Lifespan and Stable Performance
Cycle life of >3000 cycles: Significantly outperforms short-cycle batteries, reducing the frequency of replacement and lowering long-term costs, especially suitable for devices used frequently (e.g., flashlights, power banks).
Low internal resistance (≤1mΩ): Minimizes energy loss during charging and discharging, improving energy conversion efficiency and ensuring stable power output.
Wide Temperature Adaptability
Discharging temperature range of -30~60℃: Works normally in extreme cold (e.g., outdoor winter use) and high-temperature environments, suitable for devices used in harsh conditions (e.g., outdoor LED lights, industrial instruments).
Charging temperature range of 0~45℃: Adapts to most indoor and outdoor charging environments, avoiding charging failures due to temperature restrictions.
Versatile Applications
Compatible with a wide range of devices, including power banks, flashlights, headlamps, LED lights, cameras, and more. This versatility meets the power needs of daily life, outdoor activities, and professional work.Practical Design for Daily Use
Compact size (47×150mm) and lightweight (480±50g): Easy to carry and install in small devices, saving space and reducing the burden on portable equipment (e.g., portable printers, interphones).
Stable charge and discharge: Standard 0.5C charge/discharge current and 1C max current balance safety and efficiency, extending battery life while meeting basic power demands.
