II To Order No. Customer's No. Re J.B.58. was then charged up again, emptied of acid, washed out with distilled water, & then filled up with fresh acid of 1250 S.G. Following this was a further charge of 150% with no better results than previously obtained, except that the density was higher being approx 1240. It was allowed to stand again for 3 days & it still loses its charge, the density going down to below 1100 & the voltage also dropping, so that it appears that washing out will not put it right. Probably because the sediment is too hard set in the bottom to be so easily removed. Age 30 months. Signed G.J. This Sheet must be filed on completion of the work. | ||
