  If your SCRAPPER Bicycle charger LCD remains red after 4-5 hours, and the battery isn't full, consider these potential causes: * The ambient temperature is too high (40°C or above). Charge the battery in a cooler environment. * The ambient temperature is too low (under 0°C). Charge the battery indoors. * Over-discharge due to failure to charge the bike after riding.
