ABB Uninterruptible Power Supply LP11 Series UL

- 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 essential to the performance of the UPS, an automatic battery test is performed regularly to ensure failsafe operation (see section 5.5.1). When the condition of the battery is critical, the warning signal will be activated (buzzer 1x per 8 secs, and alarm message 'Replace battery', see 5.4.2). The batteries must be replaced as soon as possible. Please contact your dealer. Use only UL recognized batteries (BAZR2), valve regulated types.

NOTE: under certain circumstances a manual battery test can result in a false alarm: please see section 5.5.2 QUICK BATTERY TEST.

- Regular deep battery tests are advised in order to re-calibrate the capacity of aging batteries. See section 5.5.3 for more information.

For authorized service personnel only

- Never short the battery terminals. Shorting may cause the battery to burn.

- 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.

- The expected operational life of the cooling fans is approximately 20,000 to 40,000 hours of continuous operation. A high ambient temperature will shorten this operational life.;
