If the charge indicator shows 0%, it generally means that the battery is completely discharged. However, a 0% reading may also indicate a problem with the sensor, which could be having difficulty measuring the battery’s charge status.
It is important to note that this charge status measurement primarily applies to lithium batteries. If your boat is not equipped with a lithium battery, the charge status will not be updated correctly in the app and will remain stuck at 0%.
On the other hand, if your boat uses lithium batteries and the charge indicator shows values between 0% and 0.9%, but the batteries do not actually seem discharged, please contact the Seanapps support team at contact@seanapps.fr for assistance.
