How long do UPS batteries last? That’s one of the questions we get the most – especially when customers call us once that infamous “BEEP” warning of low battery starts. Conventional wisdom, and the most common answer to that question, is every 3-5 years – but, when you think about it, that’s a big range. Is it three years or five? Should we split the difference and say four? It depends. There are five major factors that affect UPS battery life – placement, ambient temperature, cycling, maintenance, battery chemistry, and battery storage. It’s important to learn about your customer’s environment and their battery maintenance and changing habits. You can read more about battery lifecycle in White Paper 210, Single Phase UPS Management, Maintenance and Lifecycle.
Our customers count on us to make recommendations they can trust. The last thing any of us want is for a customer to learn the hard way that they waited too long to replace a battery – like when there is that frustrating intermittent “BEEP” in the background. Think in terms of a typical small or medium sized business with single phase UPSs installed throughout their organization. When considering multiple UPSs, from a budget perspective every 3-5 years is a huge range and has a big impact on their operating budget. Do they want the expense of playing it safe and changing batteries every 3 years? Some do. Others prefer to gamble a little bit. And some try to maintain an inventory of spares – which comes with its own set of challenges like keeping them charged or possibly wasting them if they are in stored past their recommended shelf life.
Maybe a crystal ball will help?
One of the most exciting new features of the new Smart-UPS On-Line SRT models is its Intelligent Battery Management. This advanced feature provides real-time recommendations for changing batteries and helps identify which one needs replacement. This isn’t just a calendar that counts 36 months from the date a new battery was installed. Intelligent Battery Management gives customers temperature compensated charging, extending battery life and includes advanced algorithms that recommend a replacement date, based on the environment and battery cycling. The UPS can inform the user which batteries need replacement and can auto detect when additional battery packs are added. The algorithms are dynamic, constantly updating the replacement date, based on real factors and providing notice months or years in advance. That’s pretty close to a crystal ball.
With the new graphical multicolor LCD display, customers with Smart-UPS On-Line can now know precisely when they need to change their batteries and they will know well enough in advance to have a new one on hand at just the right time – no more guessing, no more risk of an unexpected failure, and no more waste. Those are some huge benefits.
Intelligent Battery Management is only one of the exciting new features in the Smart-UPS On-Line SRT models. Review the other new features of the Smart-UPS online, watch videos, download brochures, and review tools.
