The ER34615T is a D 3.6V/19Ah cylindrical-cell bobbin type Non-rechargeable Battery features a lithium thionyl chloride technology and solder tab terminals. High and stable operating voltage. High minimum voltage during pulsing. Low self discharge rate (less than 1% after 1 year of storage at 25°C). Nominal capacity at 2mA, 25°C, 2V cut-off. The capacity restored by the cell varies according to current drain, temperature and cut-off voltage. Bobbin style lithium thionyl chloride cells are maximised for long life. They offer very high energy density, low self discharge and a long storage life and are particularly suited to low current applications.
