Such components are intended for use only under limited conditions, such as certain temp
25、eratures not exceeding specied limits and shall be used only under those specic conditions for which they have been recognized.

31、tive valve. These batteries have commonly been referred to as maintenance-free, starved electrolyte. b) VENTED A storage battery the electrodes of which are made of lead and the electrolyte consists of a solution of sulfuric acid in which the products of electrolysis and evaporation are allowed to e
32、scape freely to the atmosphere. These batteries have commonly been referred to as ooded or wet. 3.5 BATTERY, NICKEL-CADMIUM STORAGE: a) VALVE REGULATED An alkaline storage battery in which the positive active material is nickel oxide and the negative contains cadmium and the venting of the products
33、of electrolysis is controlled by a reclosing pressure sensitive valve. b) VENTED An alkaline storage battery in which the positive active material is nickel oxide and the negative contains cadmium and the products of electrolysis and evaporation are allowed to escape freely to the atmosphere.
