FAQs

Why are batteries important for power protection?
Batteries provide backup power during outages, ensuring critical systems remain operational. They safeguard data, equipment, and operations from unexpected disruptions, maintaining business continuity.
How often should batteries be tested?
Batteries should be tested regularly, typically every 6–12 months, depending on usage and system requirements. Regular testing detects weakened cells or faults before they cause failures.
What is battery monitoring, and why is it needed?
Battery monitoring continuously tracks voltage, temperature, and overall condition, allowing early detection of issues. Optimised monitoring ensures batteries perform efficiently and reliably at all times.
How long do batteries typically last?
Battery lifespan varies by type, usage, and maintenance. Well-maintained batteries can last several years, but their capacity gradually decreases, making regular testing and monitoring essential.
When should batteries be replaced?
Batteries should be replaced when they show reduced capacity, fail testing, or reach the end of their expected life. Timely replacement prevents unexpected downtime and maintains reliable power protection.
Can batteries fail unexpectedly?
Yes, batteries can fail if they’re not properly maintained or monitored. Regular testing, monitoring, and timely replacement minimise the risk of sudden failure.
How do I maintain batteries for optimal performance?
Routine inspection, cleaning, testing, and monitoring are key. Keeping batteries optimised and well maintained maximises lifespan, efficiency, and reliability of your power protection system.
