Robot mower starts but stops after a few minutes with low runtime, then returns to charge

Safety: Handle the battery carefully; do not open the pack.

• Check age: Determine how many seasons the Makita mower and battery have been in use. Most packs lose capacity after several years.
• Full charge: Allow the mower to remain on the charging station until it indicates a full charge, then start a manual mow and time the runtime.
• Observe behavior: If the mower repeatedly reports low battery after a short period, capacity is likely reduced.
• Replace battery: Purchase a genuine Makita replacement battery pack specified for your model and install it per the manual.

If a new battery does not improve runtime, the charging system or battery management PCB may be at fault and require service.
