How to Prevent UPS System Battery Failure

UPS System battery failure can occur from manufacturing defects or issues caused by incorrect installation and usage. Awareness of some of the causes of battery failure can help to prevent damage and troubleshoot problems if they occur.

Common causes of UPS System battery failure:

Physical Damage – Damage can occur if a battery is stored, transported, or installed without care or against manufacturer guidelines. The manufacturers packaging should be used for transportation and care should be taken during the installation.

Sulphation – When a battery is left in a discharged state, a chemical reaction occurs. This reaction is called “sulphation” and will permanently cause damage to the battery performance.

Over Cycling – UPS batteries are designed for standby use over a short period of time. The batteries can only withstand a limited number of cycles. When a battery is cycled, there is a reduction in battery performance.

Over Charging – The charging properties of the batteries should be set in line with manufacturers recommendations during installation or replacement. If the charging voltage or current applied from the UPS is too high, the batteries can overheat.

Under Charging – Under charging happens when the UPS is not capable of applying the correct charge voltage or current to restore the batteries to a full state of charge.
