Intermittent Test - A test during which a battery is subjected to alternate periods of discharge and rest according to a specified discharge regime.
Bobbin - A cylindrical cell design utilizing an internal cylindrical electrode, and an external electrode arranged as a sleeve inside the cell container.
Discharge Rate - The rate, usually expressed in amperes, at which electrical current is taken from the battery.
Current (float) - DC current that maintains the battery at nominal charge, corresponding the float voltage. This current compensates open circuit losses.
MTTF (Mean Time To Failure) - Mathematical calculation of the duration of normal operation of a non-reparable device, i.e. for which a MTBF is not possible. The product, expressed in hours, is an indication on the reliability of the device.
IEC (International Electrotechnical Commission) - Advisory organization that draws up international standards in the electrotechnical field.
Reversal - The changing of the normal polarity of a battery due to overdischarge.
