Batteries that are Safe and Effective
When carried out correctly, the replacement of UPS batteries is a safe and effective procedure, reducing unnecessary spend. There are, however, significant risk factors associated with UPS battery replacement if not carried out professionally:
– The load may cease to be protected by the UPS. Faulty cabling can cause an inverter/rectifier breakdown, therefore switching into the auxiliary supply, and leaving the load unprotected.
– The probability of a fault can be increased through electrolyte leakage associated with the incorrect handling of battery.
– Serious injury to personnel can occur where there is spillage of electrolyte in the areas surrounding the UPS and battery installation.
– There is a risk of thermal runaway, fire or explosion if the battery charger calibration is incorrectly handled.
