HOW OFTER SHOULD I REPLACE MY UPS BATTERY?
Battery failures are the primary reason for UPS failures, leading to significant disruptions during power outages. UPS systems commonly use lead acid batteries, particularly VRLA, which are sensitive to temperature; optimal performance occurs at around 20°C. Battery life diminishes significantly as temperatures exceed 25°C, cutting in half for every 10°C increase. Factors contributing to high temperatures include ambient environment and heat generated during operation. Adequate cooling and ventilation are crucial for maintaining battery health. Additionally, frequent discharge-recharge cycles negatively impact battery longevity. For UPS battery replacements, contact Power Continuity.
Battery failures are the main cause of a UPS failure. Of causing significant disruption to your load in the event of a power cut.
You might well ask why do batteries require replacing?
Most UPS systems use lead acid batteries (and in particular VRLA) of which the single most common cause of premature failure is temperature. The optimum performance temperature (and the one that manufacturers use when stating the batteries life expectancy) is 20 ºC plus or minus a degree.
The general rule of thumb is that the battery life is halved for every 10°C above 25°C.
High battery temperatures causes;
- The ambient temperature of the environment.
- The heat which is generated by the batteries themselves.
When discharging, batteries absorb heat. As batteries charge, they give off heat at the rate of around 0.02 Watts per Ah per 12V DC. It’s therefore important to ensure that the cooling system maintains optimum battery temperatures. Its also important that there is sufficient space around the battery blocks to allow ventilation.
A second major contributory factor to reduced battery life is the number of battery discharge-recharge cycles. The amount of energy that a battery delivers during a discharge directly impacts on the life of the battery.
