Specific gravity: 1.260-1 .280 maintained !20 ° C: 68°Fl Vo ltage: When Iorge volume of gas is emitted f rom the bottery (in about 2-3 hours for fully discharged battery!, reduce charging rote to 0.2A. Battery is fully charged w hen a vo ltage of 7.5V is maintained
When the charging is urgent, quick charging method may be used, however, the recommended charging cu rr ent rote should be under 2A. If the charger is equipped with a timer, the specified method shou ld be followed. The rapid charge method above refers to battery charging with a o Pdard charger.
TROUBLE SHOOTING AND PREVENTATIVE MAINTENANCE The battery is being recharged all the while the engine is running . Further, while running, the load such as the use of the turn signal lamps horn are placed on the battery (discharged!, as the resu lt, the battery is qeing discharged at the same time it is being recharged. In the long run, the discharge and the recharge is in balance. The system has been designed in this manner. Under certain condition when the balance is upset, then trouble develops. To obtain maximum life from the battery, it is necessary to locale t his trouble and toke the appropriate action early. , The trouble to the battery are mainly exte rnal such as cracked case, broken terminal. disconnected lead wire. The battery condition, trouble, corrective action ore shown in the following table.
