Monitoring battery charge levels frequently prevents unexpected failures. If the motorcycle has a dual battery system, alternating the primary and secondary batteries can help balance the charge levels. Aim to check levels every few weeks, particularly before long rides. The U.S. Department of Transportation recommends daily checks before substantial journeys. -
Clean Batteries and Their Compartments:
Cleaning batteries and their compartments maintains optimal functioning and hygiene. Dust, dirt, and moisture can accumulate, leading to corrosion and other issues. Regularly wipe the surfaces and keep the area dry. A case study by the Motorcycle Industry Council (2022) showed that maintenance reduces the likelihood of costly repairs due to negligence. -
Replace Batteries Based on Manufacturer Recommendations:
Replacing batteries based on manufacturer recommendations ensures performance reliability. Generally, motorcycle batteries last about 3-5 years; however, usage patterns can greatly influence this lifespan. Following the manufacturer’s guidelines can help you determine the best replacement intervals and avoid running into issues on the road. -
Use a Battery Tender During Long Periods of Inactivity:
Using a battery tender during long periods of inactivity prevents battery discharge. A battery tender maintains the voltage and ensures the battery stays charged without overcharging it. This practice is especially recommended for riders in areas with long winters and periods of non-use. According to a report from the AMA (American Motorcyclist Association, 2020), keeping batteries charged can extend their lifespan by up to 30%.
