| - 2 - Contd. (1) Fully charge. (2) Empty out acid electrolyte. (3) Fill with pure distilled water. (4) Discharge at normal rate down to 1.8 volts per cell. (5) Remove terminals, clean, regrease and store these separately. (6) Empty out water, drain, and store in cool, dark place with vent plugs well tightened up. (7) On no account leave battery stored away with water in the cells at any time or under any conditions. (8) When putting accumulator again into use, follow maker's instructions for first charge, as if new, replacing some electrolyte with distilled water if density does too high. OTHERWISE YOUR ACCUMULATOR WILL PROBABLY BE RUINED. If you do not maintain the level of the electro-lyte, the negative plates will absorb oxygen from the air - a process which is deleterious to their correct electro-chemical condition. If you do not give the battery freshening charges the elements will slowly but surely alter their chemical condition and will be increasingly difficult to restore to the active state of a new fully charged battery. If you allow, by overdischarge, the P.D. of a cell to fall below 1.8 volts, or the density below 1150, the elements will immediately commence to sulphate, and again it will be increasingly difficult and ultimately impossible to Contd. | ||
