Installation

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.

• 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.

CAUTION!

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