7.4 Batteries
7.4.1 General
The service life of the battery is from 3 to 6 years, depending on the operating temperature and on the
number of discharge cycles.
As a healthy battery is critical to the performance of the UPS, an automatic quick battery test is performed
regularly to ensure failsafe operation (see section 4.6). When the condition of the battery is critical, a 'replace
battery' alarm will be activated (see 4.4.8). Replace the batteries as soon as possible, proceed with section
7.4.2.
NOTE
under certain circumstances a manual battery test can result in a false alarm: please see 4.6
'quick battery test'
7.4.2 Battery replacement
Please refer to figure 7.4.2. It shows a VH Series 3000VA model. The battery (tray) configuration of other
models may differ, but the basic principle is the same for all VH Series models.
NOTE
During battery replacement the UPS will not be able to support the load if a mains failure
occurs! It is recommended to switch off the load before disconnecting the DC connector as in
step 2.
1. Remove the plastic front from the
UPS cabinet (and/or battery
cabinet)
2. Disconnect the DC connector
3. Loosen the 4 screws that hold the
battery tray
4. Slide out the battery tray. Be
careful: it can be heavy!
5. Insert the new battery tray into
the UPS, fix it with the 4 screws.
6. Connect the DC connector.
7. Install the plastic front panel.

If you want to change only the batteries and not
the full tray with batteries, please contact your dealer.
General guidelines:
Don’t throw batteries
away, treat them as
harmful waste
• When replacing the batteries, use only the same type and size battery.
• Never short the battery terminals. Shorting may cause the battery to
burn. When working with batteries remove watches, rings or other metal
objects and only use insulated tools.
• Avoid charging in a sealed container.
• Proper disposal of batteries is required: refer to your local codes for
disposal requirements.
• Never dispose of batteries in a fire: they may explode.
• Never disassemble or reassemble batteries; their contents (electrolyte)
may be extremely toxic. If exposed to electrolyte, wash immediately with
plenty of water, if eye contact occurs flush with water and contact a
physician.
