UPS Systems require replacement after they reach the end of their reasonable life expectancy of 6-7 years, some lower spec models require replacement sooner. After this period the internal components such as the inverter, fans, capacitors, battery charger and intelligence module no longer provide a reliable source of protection, if they are not replaced we risk potential downtime and damage to our critical equipment. It is important to replace your batteries in (5) year design life batteries in 3-year intervals for correct UPS upkeep, (10) year design life batteries every 6-7 years. UPS Solutions will alert you in these intervals to let you know your battery is due for replacement if you have purchased the system or battery through us and/or have a service contract. A battery replacement schedule is crucial to avoid potential business downtime and damage to protected equipment. Towards the end of a batteries life expectancy, you can experience a significantly reduced run-time, overheating, battery swelling, acid leakage producing harmful fumes and loss of power and protection.
