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.
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.
