BATTERY SERVICE INSTRUCTIONS



1. CHARGE PROCEDURES

Sun-Xtender Batteries are charged at the factory and are ready for installation when they are received.
  • While in storage they should be boost charged every 90 days or when the open circuit voltage drops below 2.08 V./cell (12.5 V. for a 12 volt battery).
  • The battery temperature should be 20 C. (68 F.) or higher.
  • Boost charge the battery using a regulated constant voltage charger.
  • Set the charge voltage to 2.37 to 2.40 V./cell (14.2 to 14.4 V. for a 12 volt battery).
  • Charge the battery until the charger reaches the 2.37 to 2.40 V./cell (14.2 to 14.4 for a 12 volt battery) and leave the battery on charge for an additional 4 to 6 hours before removing it from the charger.
  • Alternately, the battery can be charged to the voltage setting until the current from the charger drops to 0.5 A. per 100 Ampere Hour rating of the battery.


    • 2. RESERVE CAPACITY TEST

    The procedure described below allows the Ampere Hour Capacity of the battery to be tested. This test will insure that the battery is capable of providing the necessary capacity to perform properly.
  • Charge the battery in accordance with paragraph 1, Charging Procedures, above.
  • With the battery temperature above 20 C. (68 F.) discharge the battery at 25 Amps to 1.75 V./cell (10.5 V. for a 12 volt battery).
  • Record the amount of time in minutes of full discharge.
  • If the battery fails to deliver 80% of its rated discharge time, the battery should be replaced.
  • The discharge times for each of the Sun-Xtender batteries are listed in the table below.

    3. CONDITIONING CHARGE

    Batteries that have not been boost charged and have been in storage for long periods (not over 9 months) or that have been operated in a partial or low state of charge for long periods (90 days or more) may need a conditioning charge.
  • Charge the battery at a constant current rate using the table below for the specific battery involved.
  • Charge the battery until its voltage remains constant or decreases slightly.
  • Remove the battery from charge. It is recommended that a reserve capacity discharge test be performed (instructions below) to insure that the battery capacity is at or above the recommended minimum 80% of its capacity.
  • After the test is completed, recharge the battery as described in Item 1.
  • During the conditioning charge process, the battery will get hot. If the battery container’s temperature exceeds 50 C. (122 F.) remove the battery from charge and contact Concorde.
