300.7 Routine Battery Inspection and Maintenance
Sealed Lead-Calcium Batteries
Sealed Lead-Calcium batteries are the most common type of battery used in standby power supply equipment. By
design it is as maintenance free as a battery can be. 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:
• Monthly:checkthesystemforproperoperation.
• Quarterly:checkthebatteriesfordeformitiesinthecasesandterminalcorrosion.Anydefectivebatteriesshouldbe
replaced. All corroded terminals, regardless of how slight the condition, are to be cleaned and retightened at once to
prevent failure of the entire battery bank.
• Yearly:Checkallbatteryconnectionsfortightnessandpropertorquespecications.
300.8 Battery Replacement Procedure
WARNING: Always use the same quantity and type of battery as replacements.
