The total Ampere-hours (Ah) delivered to the battery during charging has exceeded a predefined limit. This is typically a safety mechanism intended to prevent overcharging based on the expected or configured battery capacity, indicating a mismatch or a faulty measurement.
Click steps to track your progress.
Verify the actual rated capacity of the connected battery against its nameplate or specifications.
Check the charger's Ah limit parameter and adjust it to accurately match the battery's rated capacity if necessary.
Perform a diagnostic check on the charger's current measurement and Ah accumulation function to ensure accuracy.
