How Long Does a Motorcycle Battery Last?

Most manufacturer maintenance schedules indicate that a battery should last about 48 months, but what if you seem to need a replacement far more often? The more you ride, the better it is for your battery. However, improper maintenance — no matter how often you ride — is just as likely to drain power from your bike. So how long does a motorcycle battery last with proper care? If you ride daily, you may be able to ride for five years before changing or more by:

  • Learning the different methods for how to charge a motorcycle battery.
  • Learning how long to charge a motorcycle battery to prevent damage.
  • Removing your battery to protect it from cold temperatures.

How to Charge a Motorcycle Battery

Whether you ride every day or a few times each month, regular charging will help you to avoid an unexpected dead battery. That’s especially true if you live in a climate with cold winters, since cold weather is especially tough on motorcycle batteries. How long to charge a motorcycle battery (and how often) depends on the type of charger you use:

  • Trickle Chargers — Fully manual “trickle” chargers are the easiest charger to use. They work by taking AC power and converting it to DC.
  • Float Chargers — Another common charger type, float chargers provide the battery with a constant, gentle current.
  • Smart Chargers — Some chargers actively monitor battery charge levels and automatically cut the current supply when the battery is full.

How to Remove a Motorcycle Battery

To remove your battery safely, you must: disconnect the main fuse before disconnecting the batteryalways disconnect the negative terminal first and always disconnect the positive terminal second. With those points in mind, follow these steps to remove your motorcycle battery:

  1. Disarm the security system. With the motorcycle running, turn the security system off. Wait till the red indicator goes out.
  2. Shut off the motorcycle.
  3. Pull the fuse after waiting a second or two.
  4. Disconnect the negative terminal. On many recent models, the negative battery cavity is located on the right-side case. The terminal location will vary depending on your Harley-Davidson model, so refer to your owner’s manual or contact a Gresham-area dealership if you have trouble finding it.
  5. Remove the plastic case surrounding the negative battery terminal.
  6. Disconnect the positive terminal. With the fuse removed and the negative terminal disconnected, it’s now safe to disconnect the positive terminal. You should find the positive terminal near the fuse box, but refer to your manual if unsure.
  7. Remove the battery and store it someplace dry and out of the cold.
  8. Reinstall the battery by following the removal process in reverse, starting by reconnecting the positive terminal.
