A successful motorcycle ride is dependent on a properly functioning battery. It provides the power to get your motorcycle started and keeps your electrical systems running smoothly. But how do you know if your motorcycle battery is nearing the end of its lifespan? What are the telltale signs of motorcycle battery failure? In this guide, we will walk you through how to detect early signs of a failing motorcycle battery and understand when it's time for a replacement.

When to Replace Your Motorcycle Battery

Before we delve into the signs of a failing battery, let's answer the question, "How do I know if my motorcycle battery needs replacing?" It's important to know that the average life of a motorcycle battery is between three to five years. This lifespan can be extended or reduced depending on your riding habits, the quality of your battery, and how well you maintain it.

So if you haven't replaced your motorcycle battery in over five years or if you notice any of the following signs, it might be time to consider a replacement. Check out our extensive collection of motorcycle batteries to find the perfect fit for your ride.

Sign 1: Difficulty Starting Your Motorcycle

One of the most noticeable signs of a bad battery is difficulty in getting your motorcycle started. This could be due to your battery not being able to hold a charge. If you find that your motorcycle's engine is slow to turn over, or if the starter motor seems to be working harder than usual, your battery could be to blame. Remember, it's crucial to keep the battery charged, especially if the motorcycle isn't used regularly. A good battery charger can be an excellent investment in such cases.

Sign 2: Dimmed Lights and Weak Horn

A weak battery can lead to dim headlights and a feeble horn. These are signs that your battery isn't providing enough power to your motorcycle's electrical systems. It might still have enough juice to start the bike, but if these symptoms persist, it's likely that your battery is on its last legs.

Sign 3: Frequent Need for Jump Starts

If your motorcycle often needs jump-starting, it's a clear sign that your battery can't hold a charge. While this might get your bike up and running, it's usually a temporary fix. In such cases, consider checking out our AGM batteries, which are maintenance-free and known for their longevity and reliability.

Sign 4: Corroded or Damaged Battery Terminals

Battery terminals are key to a smooth electrical flow. If these are corroded or damaged, your motorcycle's battery might be on its last leg. Cleaning them can restore function for a time, but it is often a temporary solution. Ensure you check the battery terminals regularly for any signs of damage or corrosion.

Sign 5: Bulging Battery Case

A bulging battery case is an obvious visual clue that your battery is bad. This can happen when a battery is overcharged or exposed to excessive heat, causing the battery to swell. If you notice any physical alterations to your battery's shape, it's time for a replacement.

 

How to Check Your Battery's Health

So, how do you check the health of your motorcycle battery? One of the most reliable methods is to use a voltmeter. A normal motorcycle battery reading, when the engine is off, should be around 12.6 volts. If the reading is below 12 volts, that's too low for a motorcycle battery, and it's a sign that your battery is not maintaining a proper charge.
