OPEN CIRCUIT VOLTAGE VERSUS REMAINING CAPACITY
Open circuit voltage
Tensión sin carga
Approximate state of charge (%)
Estado de carga aproximado (%)
Open circuit voltage is measured after the battery was disconnected from any load or power source for at least 12hrs.

The rate of self discharge is approximately 3% per month @
68 ºF (20ºC). Therefore batteries need supplementary charge
according to the table below to keep its capacity.
