Yes. First determine type charger…Constant Current or Constant Voltage. If Constant Current, follow the recommended Charge Rate and Time in Gill Service Manual available on the Gill website; make sure that you have a reliable timer to terminate charge. If Constant Voltage, you could set the initial current at any of the settings you indicate. The charge would be complete when current drops below ½ ampere. test
Yes…Shut the charger off when you leave. Continue charging the following day. For best results, try to complete the charge the same day. Gill batteries do not have any “memory effect” limiting charge acceptance.
The bottom of the split ring is approximately ¾” below the opening of the cell. On the initial fill of electrolyte, put just enough electrolyte in to cover the plates/separators (approx 1/8th of an inch above the plates). Once the initial charging begins, the level of electrolyte will rise, ensure that the electrolyte is just below the bottom of the split ring. Keep final level of electrolyte below split ring, approximately ¾” below top of cell opening.
1) A possible voltage spike causing battery to overcharge, creating excessive gassing. 2) Overfilling a cell or cells with electrolyte. 3) If it’s an older battery, it is possible to have several good cells and 1 or 2 with high resistance. The bad cells will tend to overheat during charge, resulting in excessive gassing and possible leakage. 4) Loose caps may cause acid leakage.
During the initial stages of charging is the best time to add distilled water. Battery voltage should read approximately 13 volts after the battery has had a chance to rest (open circuit) for 3-4 hours.
No……not recommended! Automotive electrolyte is only 1.260 Specific Gravity. By using automotive electrolyte the battery will not function to it’s intended capacity because the cell electrolyte balance would not be up to the required levels. Gill electrolyte is 1.285 Specific Gravity. Warranty will be void if the proper specific gravity electrolyte is not used.
