Charge the battery at 15 amps for 10 minutes.DO NOT exceed 20 amps maximum recom-mended charging rate. Charge until specificgravity is at least 1.250. Total charging timeshould not exceed one (1) hour.2. After charging the battery, adjust the electrolytelevel to the bottom of the vent wells [1/4 to 1/2 in.(6 to 13 mm) above the plates].IMPORTANT: DO NOT overfill the battery.Electrolyte will overflow through the vented capsonto parts of the machine and WILL result in se-vere corrosion.3.
