6. Maintenance and Storage

6.1. Temperature Considerations

The battery features a low-temperature cut-off function to protect its lifespan:

  • Charging: Cut-off below 32°F (0°C). Recovery charging begins at 32°F (0°C).
  • Discharging: Cut-off below -4°F (-20°C).

In winter, if temperatures are too low, ensure the battery is kept above 32°F (0°C) for optimal charging performance and to prevent capacity attenuation.
