The advantages of lithium-ion batteries for UPS Systems

Although Lithium-ion UPS batteries have been around for a while, folks have been apprehensive to make the investment up front because of the cost. And that’s not entirely without merit.

Yes, lithium-ion batteries are more expensive up-front, but like anything in life, you get what you pay for. As the years have worn on however, the costs of these batteries have come down in price and made the investment significantly more attractive to business owners. 

Today, we’re going to discuss some of the distinct advantages that lithium ion batteries have over their peers and why you should consider purchasing one for your server room. Let’s jump right in.


In virtually every kind of server room setting, Lithium Ion batteries outlast lead-acid batteries. In most cases, a lead-acid battery will last about 3-5 years. With Lithium-Ion batteries, you’re looking at a lifespan of nearly 8-10 years – almost double their counterparts. So if you’re looking for a solution that’ll be a long-lasting one, Lithium-Ion batteries are the way to go.


Perhaps more than any other force, temperature has the biggest overall impact on your backup battery’s performance. And in nearly every single, setting, Lithium-Ion batteries outperform standard lead-acid batteries as the temperature gap widens. This will help your server room operate more efficiently and will reduce your maintenance costs over time. Lithium-Ion batteries can run in temperatures as high as 104 degrees without an issue, making them the most durable UPS backup power on the market. 

Faster recharge

Anytime a UPS battery has to provide backup power, it needs to be recharged. While WRLA batteries can take as long as 12 hours to charge, Lithium-Ion batteries are ready for round-2 in only 2 to 4 hours. That means substantially less risk that you’d suffer another outage before your UPS batteries have been fully recharged. 

Weight and size

Lithium-Ion batteries are a smaller and lighter battery than lead-acid batteries. This reduces the overall time it takes to install them and gives you lots more power in a battery that’s half the size. This gives you a much wider range in terms of installation options. It also helps companies maximize space. With data center space at a premium these days, that’s a significant competitive advantage. 

While it’s true that lithium-ion UPS batteries are more expensive than other, more traditional batteries, the actual cost long-term is substantially less. Lithium ion batteries last longer and will give you more dependable power.
