97 5 4 POWER SOURCE CIRCUIT Electrical An electrical container constructed of suterin is em ployed Hence it is difficult to inspect the plates or electrolyte from the exterior portion of the con tainer After the coupled electrode plate group is inserted into the electrical container the container cover is fitted and tightly sealed with a synthetic resin adhesive To the electrode plate which protrudes from the con tainer cover pitch and plates to an electrode synthetic prevent connector resin applied vibration and to is fitted with the electrode electrolyte leakage Fig 5 59 Battery components Refer to Fig 5 59 When additional loads such as lamps etc are connected to the battery terminals discharge occurs As discharge takes place the elements of the elec trode plates lead peroxide sponge lead etc are gradually transformed to sulfate The specific gravity of the electrolyte dilute sulfuric acid is gradually reduced and terminal voltage drops Since reduction of specific gravity corresponds to the degree of dis charge if the initial specific gravity is known specific gravity upon complete charge is 1 260 and that at complete discharge is 1 10 the extent of discharge Fig 5 60 Graph of specific gravity and electrical capacity and amount of remaining electricity is determined by the difference in specific gravity Refer to Fig POSITIVE ELECTROLYTE NEGATIVE LEAD DI OXIDE DILUTE SULPHULIC ACID SPONGY LEAD 5 60 The specific gravity of dilute sulfuric acid changes according to temperature It also changes in accord ance to battery type however dilute sulfuric with a specific gravity of 1 260 upon conversion at a standard temperature of 20 C is PbO2 2H2SOI 4 Pb acid employed DISCHARGE CHARGE If reverse current is applied to a battery from which PbSOi 2H2O PbSO discharge occurred the battery is charged and as charging occurs lead sulfate produced by discharging returns lead to its etc sulfuric acid original state lead peroxide sponge and the specific gradually gravity increases of the terminal dilute voltage correspondingly increases Refer to Fig 5 61 11 Battery charging discharging ratio and capacity charging ratio Battery capacity is the amount of electricity which is discharged from a completely charged battery until terminal voltage drops to a specified voltage which is designated by JIS as an average 1 75 V per cell To express this the ampere hour AH is used and dis charged current is multiplied by discharge hours Fig 5 61 Reversible reaction
