Worried about your motorcycle battery? Try this tool for a quick diagnosis

    Batteries aren't everlasting. Even the highest quality battery has a finite lifespan. This is because batteries are essentially containers of chemicals, and over time, these chemicals gradually lose their effectiveness.

    The Difference Between Dead Battery and Bad Battery

    When your motorcycle won't start, the immediate thought might be that the battery is dead. But is it truly dead, or just bad? A dead battery is one that has completely exhausted its charge and can no longer power your motorcycle.

    This typically happens if the bike has been left unused for an extended period. On the other hand, a bad battery refers to one that no longer holds a charge effectively, even if it shows some voltage.

    A bad battery may exhibit signs of damage, such as bulging, leaking, or corroded terminals. While a dead battery might be revived with a good charge, a bad battery often needs replacement.

    Regular maintenance and timely checks can prevent most battery-related issues, ensuring your ride remains smooth and uninterrupted.

    Always check for physical signs of damage, and use a multimeter to test the voltage regularly. If the voltage drops below 12.4 volts, it’s time to take action.

    How You Know Your Battery Becomes Bad

    If your bike struggles to start, the electrical components seem sluggish, or you notice dimming headlights, these are red flags. One of the most effective ways to test your battery is by using ANCLE's battery tester.

    Using the ANCEL BST600 to check your motorcycle battery is straightforward and highly effective. First, ensure your motorcycle is off, and the battery terminals are clean and free from corrosion.

    Connect the BST600's clamps to the battery terminals—red to positive and black to negative. Turn on the tester, and it will automatically begin analyzing the battery. The BST600 will display the voltage, cold cranking amps (CCA), and the battery's state of charge (SOC).

    It also evaluates the state of health (SOH), giving you a comprehensive view of your battery's condition. Follow the on-screen prompts to perform additional tests, such as a cranking test or charging system test.

    This device’s versatility makes it an invaluable tool for maintaining not just motorcycles, but also cars, RVs, ATVs, SUVs, boats, yachts, and mowers. Regular use of the BST600 ensures you can detect issues early and maintain optimal battery health. More effective scan tool all at ANCEL!

    How Many Amps Are in a Motorcycle Battery

    Motorcycle batteries come in various sizes, and their ampere-hour (Ah) ratings can differ significantly. Most motorcycle batteries range between 2 to 32 ampere-hours. Smaller bikes, like scooters, typically use batteries on the lower end of this spectrum, while larger motorcycles, such as touring bikes, require batteries with higher ampere-hours.

    It’s crucial to choose a battery that meets your motorcycle’s specifications. Using a battery with too low an ampere-hour rating can lead to frequent power issues, whereas one with too high a rating can be unnecessarily expensive.

    The cold cranking amps (CCA) is also an important factor, especially in colder climates. CCA indicates the battery's ability to start an engine in cold temperatures, which is crucial for reliable starting performance.

    What Causes a Motorcycle Battery to Overcharge

    Overcharging is a common yet damaging issue for motorcycle batteries. Several factors can cause overcharging. One primary reason is a malfunctioning voltage regulator.

    This component is responsible for maintaining the correct charge level in the battery. If it fails, the battery can receive too much charge, leading to overheating, swelling, and eventual failure.

    Additionally, using an incorrect charger or charging the battery for too long can also result in overcharging. Always use a charger that matches your battery’s specifications and follow the recommended charging time to avoid these issues. Proper maintenance and using the right equipment are key to preventing overcharging and extending your battery's life.

    Be cautious of leaving your battery on a trickle charger for extended periods without a smart charger that automatically switches to maintenance mode.

    How Long Does a Motorcycle Battery Typically Last

    The lifespan of a motorcycle battery varies based on usage, maintenance, and environmental factors. On average, a well-maintained motorcycle battery can last between 2 to 5 years. Regular use, proper charging practices, and avoiding extreme temperatures can help extend its lifespan.

    If the motorcycle is frequently idle or stored improperly, the battery's life can significantly shorten. Investing in a good-quality battery and using it regularly ensures that it remains functional for as long as possible. Regular maintenance checks and timely replacements are essential to avoid unexpected breakdowns.

    During off-season storage, it's advisable to remove the battery, keep it in a cool, dry place, and periodically charge it to maintain its health. Using a battery tender can help keep the battery in optimal condition during long periods of inactivity.


    Regular checks and using reliable tools like ANCEL’s battery tester ensure your bike is always ready for the next adventure.
