Routine Battery Inspection and Maintenance
Sealed Lead-Calcium Batteries
Maintenance-free 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. It is recommended, however, that some simple steps be taken to increase system
life and maximize reliability:
1. A quarterly visual check of the battery should be conducted to look for deformities in the battery case, electrolyte
leakage, and/or terminal corrosion. Any batteries with these conditions are defective and should be replaced. Any
corroded terminals found, regardless how slight, are to be cleaned at once to prevent system failure.
2. Once a year, all battery connections should be checked for tightness and cleaned and retightened, as necessary.
Battery Replacement Procedure
WARNINGS:
• Always use the same quantity and type of battery as replacements.
• Substituting batteries not supplied by the Manufacturer will void the UL listing of the system and may cause equipment
failure. To ensure the superior performance of your
Tucson Micro
inverter system and to maintain proper charger
operation, replace spent batteries only with those having the same part number, voltage, and ampere-hour rating as the
original batteries.
1. Follow the proper shut down procedure as described in the
Maintenance - Safe Shut Down Procedure
section on
page 11.
2. Disconnect the battery Positive red (B+) and Negative black (B-) connectors.
3. Remove the battery from the cabinet.
4. Install the new battery following the instructions outlined in the
Battery Information - Battery Installation and
Connection
section on page 9.
Battery Disposal
WARNINGS:
• Do not dispose of batteries in a fire; the batteries could explode.
• Do not open or mutilate batteries.
• Released electrolyte is highly toxic and harmful to the skin and eyes.
CAUTION:
Batteries contain lead or cadmium, depending on model. Many state and local governments have regulations
about used battery disposal. Please dispose of the batteries properly.
