    acid batteries are warranted against defects in materials or manufac- turing or both. To keep the warranty in effect, you must place the units on charge by the date stamped on the shipping carton when stored at 77°F (25°C). If storage beyond this time is required or storage temper- ature is in excess of 77°F (25°C), monitor battery voltage at monthly intervals, if possible.

  • Page 14: Section 4 - Electrical Connections

    SECTION 4 - ELECTRICAL CONNECTIONS WARNING • Always use protective insulating equipment, such as gloves, shoes and eye and face protection. Wrenches and other tools must be insulated. • Observe local, state, and national electric codes at all times. • Always work with the battery ungrounded. Battery ground connections, if required, should be made last.

  • Page 15: Connecting And Torquing Battery Terminal Posts

    CAUTION Do not use steel brushes, steel wool, sandpaper or emery cloth to clean surfaces, as these will damage the plating. Do not use cleaning solvents. Solvents can cause crazing or cracking of the plastic cell containers or covers. Use of solvents will void the warranty.

  • Page 16: Checking Connection Integrity

    CAUTION Use extreme care when installing connectors; maintain a firm grasp on each connector as it is being installed, to prevent it from dropping and potentially causing a short circuit. Note: Over-torquing can damage the post seal causing electrolyte leakage. 4.4 Checking connection integrity •...
  • Page 17 resistance for each battery. A wide variation in circuit resistance can result in unbalanced discharging and charging of cells. As a consequence this can produce unequal float voltages of the connected cells and individual strings can sustain a loss of performance and capacity, resulting in higher loads on the other parallel strings with lower cable (circuit) resistance.

  • Page 18: Charging And Operation Of Battery

    PART 2 CHARGING AND OPERATION OF BATTERY SECTION 1 - CHARGING 1.1 General Information and Precautions To safely charge the Liberty Series 1000 batteries and avoid damaging the battery and/or connected equipment, observe the following: • Use only direct current for charging. AC ripple current from charger must not exceed 5 percent of the 8-hour (Ampere-hour) rating of the battery.

  • Page 20: Initial Charge Records

    minimum of 72 hours before any load is placed on the system. The battery is now considered fully charged and is ready for either initial acceptance testing or regular service. Use only direct current for charging. AC ripple current from charger must not exceed 5 percent of the 8-hour (Ampere-hour) rating of the battery.

  • Page 21: Equalizing Charge

    For optimum service, adjust the power supply to the float voltages shown in Table 3. If the power supply is intermittent or more frequent discharges are anticipated, use a higher value recommended voltage setting. Note: For locations that exhibit frequent temperature variations it is recommended that temperature compensated rectifiers be used that adjust the voltage in accordance with sub-sections 3.4 and 3.5 of Section 3.

  • Page 22: Voltmeter Calibration

    To avoid over-voltage, periodically check battery voltage with a calibrated digital voltmeter. If an over-voltage is recorded, check and readjust the rectifier and/or panel meter calibration as necessary. Place the battery at the recommended float charging voltage as soon as possible.

  • Page 23: Capacity And Testing

    3.2 Capacity and testing Batteries are rated in Ampere-hours or kiloWatts on their ability to deliver a certain number of amperes or power, respectively, to the load for a specified amount of time before cell voltages drop to a final design potential.

  • Page 24: Effects Of Temperature

    When the voltages of individual cells are lower than normal, it is possible to conclude that insufficient charging has occurred. The following are possible causes of cell voltage variations: • Panel voltmeter reading high - This results in a low float voltage. Re-calibrate the panel voltmeter.

  • Page 25: High Ambient Temperature

    If continuous adjustment of the battery plant charger voltage relative to ambient temperature is impractical, it is recommended the appropriate fixed float voltage setting of Table 4 is used. At temperatures below 77°F (25°C), battery capacity will be reduced by approximately 0.5 percent per degree Fahrenheit. Caution must be exercised when operating or storing batteries at low temperature because of the possibility of electrolyte freezing.

  • Page 26: Cleaning Cell Covers

    3.6 Cleaning cell covers • Cell covers can be dusted with a clean cloth or clean dry paintbrush. • Cell covers may also be cleaned with clear water and a small amount of baking soda and dried after cleaning. • If residual acid appears on the cover surfaces it may be neutralized with a solution of one pound baking soda and one gallon of clear water.
  • Page 27 completely recharge the battery and take a set of voltage readings, recording them for future reference if the readings are satisfactory. Provide remedial action or an equalize charge if necessary. Do not discharge a battery below the design final voltage. Remedial action may be required if the battery was discharged below its final design voltage.

  • Page 28: Trouble-Shooting And Avoiding Battery Degradation And Recognizing Problems

    PART 3 TROUBLE-SHOOTING, AVOIDING BATTERY DEGRADATION AND RECOGNIZING PROBLEMS SECTION 1 - HOW TO AVOID BATTERY DEGRADATION 1.1 General Information and Precautions Properly maintained and charged, Liberty Series 1000 batteries will provide many years of trouble-free service. However, despite their inherent dependability, failure to operate and maintain them correctly can lead to damage, shortened service life or cause loss of service.

  • Page 29: Low Float Voltage And Sulfation

    CAUTION RECHARGE BATTERIES AS SOON AS POSSIBLE AFTER AN EMERGENCY DISCHARGE. Failure to recharge batteries immediately after emergency discharge may lead to sulfation or, in the case of deep discharge, to complete battery failure due to hydration. If recharging at equalize voltage is impractical, recharge at float voltage.

  • Page 30: Parallel Battery Strings

    the affected cells may become sulfated and require corrective action. 1.6 Parallel battery strings When strings of batteries of equal voltage are connected in parallel, the overall capacity is equal to the sum of the capacities of the individual strings. When paralleling valve-regulated batteries is necessary, the external circuit resistance must be matched for each battery.
