Possible Causes

Non-genuine or incompatible battery pack, Faulty battery management PCB, Loose battery connector, Corroded battery terminals

How to Fix / Troubleshooting

Safety: Turn OFF the mower and remove the battery compartment cover according to the Makita manual.

  • Verify battery type: Ensure the installed battery pack is the correct Makita model specified for your robot mower.
  • Check connectors: Inspect the battery plug and socket for bent pins, corrosion, or loose fit. Reseat the connector firmly.
  • Clean terminals: If there is light corrosion, clean contacts gently with a dry cloth. Do not use water.
  • Reinstall battery: Secure the battery in place so it cannot move during operation.
  • Reset: Refit the cover, power ON, clear E10, and attempt to start.

If E10 persists with a correct, genuine battery, the internal battery management circuitry or main PCB may be faulty and require professional service.
