3.6.2 Battery Replacement

Only authorized service personnel familiar with battery systems may replace batteries. See the “Start-up & Shutdown Procedure” section in this Installation Guide to bypass and shut down the UPS.

CAUTION!

Study all warnings at the beginning of this section before replacing the batteries.

•Use the Same Battery Number and Type: To ensure a well-functioning UPS and to maintain proper battery charger operation, you must replace a given number of batteries with the same number of batteries. The batteries must be the same manufacturer type as the original batteries and have the same voltage and ampere- hour rating as the original batteries.

•Verify that the Battery Terminal is not Grounded: If any battery terminal is inadvertently grounded, you must remove the connection from the terminal to ground (earth) before you service the batteries. Contacting any part of a grounded battery can cause a risk of electric shock. To reduce the risk of electric shocks, disconnect the ground connection before you service the batteries.

•Handle Used Batteries with Care: Assume that old batteries are fully charged. Use the same precautions you would use when handling a new battery. Do not short battery terminals or the battery string with a cable or tool when you disconnect the batteries.

•Dispose of Batteries Properly: Do not dispose of batteries in a fire as the batteries may explode. Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes and may be toxic. Batteries contain lead. Many state and local governments have regulations about disposing of used batteries. For assistance, call APC Technical Support or call your local APC office.
