Possible Causes

Charging base not supplying maintenance current, Dirty contacts causing intermittent connection, Faulty battery pack self-discharging, Base power supply intermittent

How to Fix / Troubleshooting

Safety first: Disconnect mains power before cleaning contacts or moving the base.

Steps to check:

  • Clean contacts: Thoroughly clean the mower and base charging contacts.
  • Check base LED: Ensure the base indicates normal operation when the mower is docked.
  • Test power supply: Verify the AC adapter is warm (not hot) and its LED (if present) is on.
  • Battery age: Replace an old battery that may be self-discharging excessively.

When to call a technician: If a new battery still drains on the base, the charging base PCB or mower charging circuit likely needs replacement.
