The most obvious explanation is that the battery has reached the end of its service life by normal wear, so it has shedded most of its active mass.

The service life of deep cycle batteries largely depends on the depth of discharge. In fact, the service life of a deep cycle battery is often determined at the moment of purchase, when it is dimensioned. It is at that point, when making the calculation of power consumption and charging facilities, that the number of cycles to expect are decided upon.

Deep discharge due to lack of capacity of the battery, charger or alternator may also have accelerated loss of active mass and cause short cycle life.

Another possible cause of premature battery failure is sulphatation, In general, sulphatation results from two factors: state of charge and the time the battery discharged. Sulphatation not only hampers the charging process, but it can also form large crystals which bridge between two plates. And cause a short circuit. In the event of such a short circuit the battery voltage will rapidly increase when connected to a charger. The charger will see this as an indication that the battery is fully charged and cut off, leaving the battery empty.
