The procedure for con-ducting such tests is in general as follows: 1. The following readings taken while battery is on charge and just priorto discharging: (a) Voltage of each cell. (b) Specific gravity of each cell. (c) Temperature of each cell. 2. Cut the battery in on discharge, regulate the current to the propervalue as quickly as possible. 3. After discharge has r

After discharge has run for from five to fifteen minutes take voltagereading of each cell. Select cells having lowest voltage for use as pilot cells. 363 Storage Battery Manual 4. Take individual cell voltage, specific gravity, and temperature readingsevery 30 minutes. 5. During thfi last hour of the discharge take overall readings as aboveevery 15 minutes. 6. Upon completion of the test take overall readings as above. 7. If the battery fails to deliver the required capacity all other batteriesof the type on the order are held up pending a satisfactory test for Pig. 132i.—Assembling the Elements.—Portable Type Batteries. If the batteries are properly rated, and contain no defects, the capacityshould be obtained v?ithin the first three cycles of charge and discharge. Check Dimensions, Construction and Weight.—The dimensions, con-struction and weight of the batteries should be checked up to see that theyconform to the specifications. An approved drawing or blueprint is usuallyprovided for this purpose by the battery manufacturer. Pig. 1321 showsoperation of assembling the elements of portable types of batteries by plac-ing the groups of plates together.
