Wear eye protection and have fresh water available in case there is contact with the battery acid. It is the user''s responsibility to operate the equipment in a safe manner.
used to describe battery cells, modules, and packs. • Nominal Voltage (V) – The reported or reference voltage of the battery, also sometimes thought of as the "normal" voltage of the battery. • Cut-off Voltage – The minimum allowable voltage. It is this voltage that generally defines the "empty" state of the battery.
