Capacity Test. This cell on its preliminary discharge at 5 amperes gave 36.2 ampere hours. After a further good charge the cell was left standing for 2 days when another discharge was taken at 5 amperes & only realised 20 ampere hours. This was considered a very poor result & consequently another discharge was taken immediately after charge & 28.5 ampere hours were obtained. Although this result is not good it bears out that leakage does occur as suggested in the report J.R.146 18-1-26. Signed: F.J. This Sheet must be filed on completion of the work. | ||
