Yes, motorcycle batteries can die when not in use for an extended period. There are a few reasons why this can happen:
Self-discharge: All batteries, including motorcycle batteries, experience self-discharge over time. This means that even when not in use, the battery gradually loses its charge. The rate of self-discharge can vary depending on the battery's quality and age but is generally more pronounced in older batteries.
Parasitic drain: Some motorcycles have electrical components that continue to draw a small amount of power even when the bike is not running. These components, such as clocks, alarms, or electronic systems, can slowly drain the battery over time if the bike is not used regularly. This drain is referred to as parasitic drain.
Sulfation: If a motorcycle battery is left discharged for an extended period, sulfate crystals can form on the battery plates. Sulfation is a common cause of battery failure and occurs when the battery isn't regularly charged. These sulfate crystals can hinder the battery's ability to hold a charge and reduce its overall capacity.
To prevent your motorcycle battery from dying when not in use, here are some steps you can take:
Regular maintenance: Proper battery maintenance is crucial. Keep the battery clean and free from dirt and corrosion. Inspect the battery terminals and connections for any signs of damage or loose connections. Tighten or clean them as needed.
Charge the battery: If you're not planning to use your motorcycle for an extended period, it's recommended to keep the battery charged. Use a compatible battery charger or a maintenance charger to maintain the battery's charge level. Follow the manufacturer's instructions for charging and maintaining the battery.
Store the battery properly: If you plan to store your motorcycle for an extended period, it's advisable to remove the battery and store it separately in a cool, dry place. Make sure the battery is fully charged before storage. You can also consider using a battery maintainer or tender during storage to keep the battery in good condition.
Start the motorcycle periodically: If you can't remove the battery, another option is to start the motorcycle periodically and let it run for a short time. This helps keep the battery charged and prevents excessive discharge.
Disconnect the battery: As a last resort, if you're unable to charge or maintain the battery regularly, you can disconnect it from the motorcycle. This prevents any parasitic drain and reduces the chances of the battery dying. However, keep in mind that disconnecting the battery may result in the loss of settings or data in electronic systems, such as clocks or alarms.
By following these preventive measures, you can help extend the lifespan of your motorcycle battery and minimize the risk of it dying when not in use for an extended period.
