Display shows “Error 16 – Low battery” and the mower stops far from the charging station.

Safety first: Press STOP and switch OFF the mower before opening any covers.

• Check charging behavior: Place the mower on the charging station and confirm the charging indicator shows active charging until full.
• Inspect battery connections: Open the battery compartment according to the Gardena manual. Ensure the battery plug is firmly connected and free of corrosion.
• Evaluate runtime: After a full charge, time how long the mower operates before reporting low battery. If significantly shorter than specified, the battery is likely worn.
• Environmental factors: Very cold or hot conditions can reduce runtime. Try operating in moderate temperatures.

Most low-battery issues on older units are resolved by installing a new original Gardena battery pack.
