A dead battery could indicate a problem with your motorcycle charging system

Prior to installing a new battery it is highly advisable that you test your motorcycle charging system to eliminate any other potential causes. Otherwise you may damage the new battery.

Continuing to ride with a faulty charging system can cause further damage to your wiring and connectors as in the photo above.

Possible causes for failure of the charging system are:

  1. Riding short trips (under 15 minutes)
  2. Old wiring or brittle parts
  3. Short circuits in wiring harness
  4. Using a lot of other gadgets such as phone chargers, extra lights, GPS which require a longer period of riding to allow the stator to fully charge the depleted battery
  5. Faulty ECU

It is advisable to connect your battery to a smart trickle charger with a desulphator mode, such as an Optimate 4, when the bike is parked and not in use. This can prolong the battery life for up to 5 years, and avoid costly breakdowns due to regulator rectifier or stator malfunctions.
