  • Page 74 MAINTENANCE BATTERIES The batteries are unique in that they hold their power for long periods of time. The lifetime of the batteries is limited by the number of charges the batteries receive. To get the most life from the batteries, charge them when all the battery discharge indicator segments shut off (20% charge left).

  • Page 75: Battery Charge

    MAINTENANCE NOTE: Do not take readings immediately after adding distilled water. If the water and acid are not thoroughly mixed, the readings may not be accurate. Check the hydrometer readings against the following chart to determine the remaining battery charge level: SPECIFIC GRAVITY at BATTERY 27_ C (80_ F)
  • Page 76 MAINTENANCE 5. Check the electrolyte level in all the battery cells. 08247 6. If the level is low, add just enough distilled water to cover the plates. DO NOT OVERFILL.
