-221- Contd. and the sulphuric acid in the solution. A battery will sulphate itself up in a similar manner if left for any length of time in a run down condition. Therefore, in storing a battery for a long period it is necessary to remove the acid as explained above. Under these circumstances it is impossible for sulphate to be formed because one of the components of this sulphate has been removed. The battery, therefore, can be allowed to discharge to a dead condition without injury when the acid is replaced by distilled water. R.R. 235a (500 (T) (S.D.) 408. 26.4.17.) Bm. 2159/13. | ||
