Batteries are not eternal. Even the best quality battery has a maximum life expectancy. That’s because batteries are essentially boxes of chemicals and chemicals lose potency over time.
Difference Between a Dead Battery and a Bad Battery
Almost everyone has left their headlights on all night at some point. This slow draw of energy without the ability to recharge from the alternator is sure to drain the battery and cause it to “die.” In most cases, dead batteries can be revived by a jump start. The same is not true for a “bad” battery.
When a battery goes bad, there is no way to revive it. No matter how much you charge it, a bad battery won’t hold a charge.
Rule Out Other Potential Causes
The first step in any mechanical diagnosis is to rule out all the potential causes of the problem. If your battery is less than three years old, has never gone uncharged for a long period of time, and doesn’t show any visual signs of damage, there may be other reasons your bike won’t start.
Before you invest in a new battery, inspect the wiring, check if terminal connections are loose or corroded.… you may even want to have your motorcycle professionally inspected to make sure it’s not an issue with your alternator or another mechanical component. Remember that many modern motorcycles are outfitted with a safety feature that prevents the bike from starting if the transmission is in gear and the clutch is not engaged, so always make sure you have the proper conditions to start your bike.
Some of the most obvious signs of a bad battery are visual indications. These include: a broken terminal, a crack or bulge in the plastic casing, as well as any leaking or discoloration.
Sometimes, battery terminals can become corroded. In most cases, it’s possible to clean corroded battery terminals and continue using your battery, so make sure any signs of wear or discoloration are not a result of normal corrosion before you deem your battery “bad.”
The surefire way to determine the health of your battery is to use a battery tester. A professional quality tester will be designed specifically for powersports batteries and provide recommended actions.
If your battery is indeed bad, the only solution is to replace it. Don’t choose just any replacement battery. Any time you need to purchase a replacement part for your motorcycle, it’s best to select a reputable brand so you don’t face the same issue again for a very long time. Yuasa batteries are the number one choice of motorcycle manufacturers worldwide, because the quality and longevity of Yuasa batteries far exceeds that of its competitors. So next time you need to replace your motorcycle battery, choose Yuasa.
