Not illustrated. 1902 Excerpt: ...on the positive plate over to the negative. If the cell be charging, the cadmium in the liquid must be removed, and the copper end of the contact piece pressed against the negative lug, while the contact which was on the positive lug is taken away, and its cadmium end placed in the electrolyte. (6) The charging rates are usually given by the makers, but in absence of any instructions, it may be determined approximately by calculation, taking.040 amperes per square inch of positive plate surface as normal. This can be checked after a few trials, by the length of time elapsing from beginning to the end charge, as evidenced by the voltage rising to 2.5 and vigorous evolution of gases, called "boiling." The eight hour rate is usually taken as the normal in power station cells, and the four hour rate in motor car batteries. The maximum charging rate is that at which the cell wiil absorb energy without heating more than 25 F. above surrounding atmosphere, or excessive gassing. Usually this will be found to be not greater than the two hour rate, and if it be at the beginning of charge less than this rate. (7) The normal discharge rate may be taken as equal to the normal charge rate--usually taken as the eight hour rate. The maximum discharge rate should never be greater than the one hour rate, though it is claimed by the makers of certain Plants elements that their cells will stand discharge at the thirty minute rate, provided the full capacity be not taken out. After determining (1) to (7) inclusive, the battery should be given several cycles of charge and discharge at normal rates, to bring it up to good working condition, before going on with the tests following. (8) The capacity at normal discharge rate should first be determined. Charge at normal r...
