To replace the batteries:
1.
Use the same number and type of battery.
To ensure continued superior performance of your UPS and to
maintain proper charger operation, you must replace the batteries in
the UPS or its battery cabinets or racks with the same number of
batteries. These batteries must be the same type as the original
batteries: valve-regulated, low-maintenance. The replacement
batteries should have the same voltage and ampere-hour rating as
the original batteries.
2.
Remove the ground from the battery terminal.
If your local or national code requires you to ground either battery
terminal, remove the connection from the terminal to ground (or
earth) before you work on the batteries. If any battery terminal is
inadvertently grounded, remove the source of the ground.
Contacting any part of a grounded battery can cause a risk of
electric shock. An electric shock will be less likely if you disconnect
the grounding connection before you work on the batteries.
3.
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! See “Recycling the Used
Battery” on page 74 for proper disposal.
