How to Replace a Motorcycle Battery
Effective motorcycle maintenance includes performing regular upkeep and replacing certain part when needed. That includes your bike’s power plant: the battery. Conventional batteries typically last two to five years, according to Yuasa Batteries. If you believe your battery may need to be replaced, consider motorcycle enthusiast Matthew Bochnak’s tips for doing it right.
Hey what’s up everyone, it’s Matt from HowToMotorcycleRepair.com. In today’s video, I want to show you how to replace your motorcycle’s battery.
Now there are a couple or reasons why you may need to replace your battery: 1. You try to start your motorcycle, and the engine cranks over slowly or does not crank at all. 2. The battery is 3 to 5 years old and you want to replace it as a preventative measure, so you don’t run the risk of being stranded somewhere.
Now, before we begin working on the motorcycle, I do want to mention that if you are unsure or uncomfortable with any of the procedures mentioned in this video, please seek the help of a professional mechanic. Also, make sure you wear the proper safety equipment for this project: gloves and safety glasses are a must. Also, make sure the ignition key is in the “off” position for this entire procedure.
Batteries on motorcycles are typically located under the seat, so let’s start by removing it. You may also have to remove the side cover, depending on the model you are working on. Slide the battery out to gain access to the battery terminals. When disconnecting the battery cables, always disconnect the negative cable first. If you were to try and disconnect the positive cable first, the wrench may contact the frame and cause a short. That is because the frame is connected to the battery’s negative terminal, and the wrench would be on the positive terminal, so you basically would have created an unintended circuit, or short. Next, disconnect the positive battery cable and remove the battery.
To confirm if your battery needs replacement, it would be best to take it to your nearest motorcycle dealer and have them fully charge and load test the battery. A load test will determine if the battery is good or not. Even if the battery is able to hold a charge, it is possible that it may not pass a load test. If the battery fails the load test, then you have no other choice but to purchase a new one.
For this project, I ordered the replacement battery online. If you happen to have a new battery shipped to you, it will typically arrive dry, and you will have to fill it with the included electrolyte. Let me quickly explain how to do this. Remove the seal from the battery. Flip the electrolyte pack upside down and line it up with the battery. Apply a little downward pressure to break the seal. The electrolyte pack will take about 5 minutes to fill the battery. Allow the battery to sit for 15 to 30 minutes before installing the cap with a soft hammer. Charge the battery for the amount of time and amperage outlined in the instructions provided. Once charged, the battery is ready for use.
Slide the new battery into the battery box on your bike. If the battery cables are dirty or corroded, you can clean them up with a wire brush. When reconnecting a battery, always attach the positive cable first. This way, the frame is not grounded to the negative terminal yet, and you can help prevent a short. After the positive cable is hooked up, go ahead and attach the negative cable. Make sure all connections are clean and tight. Confirm that any protective terminal caps are installed properly. Reinstall the side cover and seat.
