DUAL LITE SYNCHRON - Routine Battery Inspection and Maintenance; Battery Replacement Procedure

16
CAUTION:
A battery can present a risk of electrical shock and high short circuit current. Battery replacement should only
be performed by qualied service personnel familiar with battery systems. All safety precautions outlined at the
beginning of this section must be observed when servicing, maintaining or replacing batteries
Routine Battery Inspection and Maintenance
Sealed Lead-Calcium Batteries
Lead-Calcium cells are the most common type of battery used today in standby equipment. By design it is as
maintenance free as a battery can be. Coupled with the diagnostic and self-testing capabilities of the Synchron
system, these batteries provide one of the most reliable and carefree inverter systems available today. It is
recommended, however, that some simple steps be taken to increase system life and maximize reliability:
• If system is installed in a remote area where the system's alarms may not be heard, it is recommended that the
system be checked weekly for alarm conditions,
• A quarterly visual check of the batteries should be conducted to look for deformities in the cases and terminal
corrosion. Any defective batteries should be replaced. All corroded terminals, regardless how slight, are to be
cleaned and retightened at once to prevent failure of the entire battery bank.
• Once a year, all battery connections should be checked for tightness and re-torqued if necessary. Torque
specications can be found on the battery label, or in this manual.
Battery Replacement Procedure
WARNING: Always use the same quantity and type of battery as replacements.
Substituting batteries not supplied by Dual-Lite will void the UL listing of the system and may cause equipment failure.
To ensure the superior performance of your Synchron inverter system and to maintain proper charger operation,
replace spent batteries only with Dual-Lite cells having the same part number, voltage and ampere-hour rating as the
original batteries.
1. Follow the proper shut down procedure as described in Section 300.1.
2. Remove battery cabinet fuses and test them for continuity. Faulty fuses will prevent batteries from charging and
render the battery bank useless during a power outage.
3. Break down the battery bank beginning with the intercell connectors. These cables tie the batteries installed on
the same shelf together.
4. Next remove the inter-tier cables. These cables connect the batteries located on different shelves together.
5. Remove the batteries from the cabinet. Batteries can be very heavy, use proper lifting methods when removing
battery.
6. Install new batteries following the instructions outlined in Section 105.3.
Battery Disposal
WARNINGS:

Do not open or mutilate batteries.
Released electrolyte is highly toxic and harmful to the skin and eyes.
CAUTION:
Batteries contain lead. Many state and local governments have regulations about used battery disposal. Please
dispose of the batteries properly. For help, contact the Dual-Lite Technical Support Center.
