If you are already considering moving to an uninterruptible power supply (UPS), then you know that it will provide you with the most reliable power supply. A UPS will also keep your business or organization online when you need it the most. But which UPS should you invest in? While a lithium-ion UPS costs more upfront, it is also a more cost-effective solution in the long run. In this blog post, we are going to explore some of the reasons why you should make the switch to lithium battery technology in your uninterruptible power supply system. Let’s get started!
Longer Life, Low Maintenance
Did you know that lithium-ion batteries last up to twice as long as lead-acid batteries? Lithium-ion UPS batteries can last eight to ten years or even longer with the proper maintenance, meaning the batteries can last as long as the UPS itself. This reduces operational costs and shrinks the risk of downtime during maintenance. Also, lithium battery technology withstands many more charge and discharge circles than lead-acid batteries.
High Temperatures Are Not a Problem
Unlike lead-acid batteries, lithium-ion batteries can withstand high temperatures with no drop in performance. A lead-acid battery loses about half of its life expectancy for every 15°F temperature increase above 77°F, while lithium-ion batteries can function at temperatures of up to 104°F with no performance issues. This means lithium-ion UPS’ can be used in harsher environments where lead-acid batteries simply could not function.
Smaller, Lighter, and Flexible
Lead-acid batteries are not known for being light or compact, but luckily lithium-ion batteries are both. They are 40% to 60% lighter than their lead-acid counterparts, and about 40% smaller in size. So not only do you get flexible installation options, but you can get far more runtime out of your UPS in the same amount of space, or the same runtime in a smaller space.
Once your UPS has provided backup power, its batteries must be recharged as quickly as possible. Lithium battery technology takes only two to four hours to reach 90% of its runtime capacity. This means that the risk that you will suffer another outage before your UPS batteries have been fully charged is almost zero.
Integrated Battery Management System (BMS)
Lithium-ion batteries are unique in that they feature an integrated battery management system (BMS), which helps to protect the cells against a host of issues. These can include temperature and current fluctuations as well as over or under-charging. BMS optimizes the charging of your lithium-ion batteries throughout their operational life, which maximizes performance.
Lower Total Cost of Ownership in the Long Term
Lithium-ion batteries deliver a total cost of ownership savings of up to 50% over their lifetime. This means that while you might spend more on the initial investment into a lithium-ion UPS than you would into a lead-acid battery UPS, you will get a hefty return on your investment. This is due to several factors, including:
Longer lifespan versus traditional batteries.
Ability to withstand more charge and discharge cycles, as well as higher temperatures.
Reduced maintenance costs, since there are no battery replacements under normal circumstances.
A smaller footprint drives down space requirements and installation costs.
