Lithium Ion in the Data Center?
The chemical composition of li-ion batteries often varied drastically by manufacturer, making the batteries less reliable, stable, and safe overall — not exactly good justification for their significantly higher price tag. And with so many customers counting on data centers to deliver promised uptime, only the best, most reliable power sources could be utilized, which up until recently included VRLA (valve-regulated lead-acid) batteries.
But now li-ion batteries are coming to the fore as a real solution for data center UPSs — in large part because manufacturers of consumer electronics, smartphones, and electric vehicles have pushed heavily for li-ion innovation and improvement, while VRLA technology hasn’t changed much in recent decades. The strides made with li-ion are paying off. It’s now predicted that by 2025, li-ion will increase to 35% of the market, up from just 1% in 2016.
As data centers everywhere seek to cut operating costs, become more efficient, and maximize space without sacrificing service or performance, they’re seeing the myriad benefits of the newest generation of li-ion batteries now available, which are proving to be more powerful, reliable, long-living, and cost-efficient, than their old VRLA predecessors.
Top manufacturers of li-ion batteries are now making them specifically for data centers that were previously using VRLA batteries, helping them make the switch and reap a number of benefits to business — benefits which in turn get passed on to data center customers via enhanced service, competitive pricing, greater reliability, and other factors:
1. Lower cost of operations.
While the initial cost of a li-ion battery may be higher than a VRLA battery, the total cost of operation ends up much less over time, saving organizations 30-50%.
2. Fewer refreshes.
The life expectancy of a li-ion battery is 15 years, as opposed to just five years for a VRLA battery, resulting in fewer battery refreshes.
3. Less risk.
With fewer li-ion battery refreshes required, the risk of incidents during battery replacement work is lower as well, meaning higher reliability.
Smaller footprint. With 60-70% less weight than a VRLA battery and 40-60% less size overall, the footprint of a li-ion battery is much smaller, giving data centers more floor space for data and IT management.
4. Less time to charge.
A typical li-ion battery can be fully recharged in about two hours, unlike a VRLA battery that requires 10-12 hours.
5. Reduced cooling costs.
Li-ion batteries are designed to safely operate at higher temperatures with much less degradation than VRLA, allowing data centers to cut down on cooling investments for gray spaces.
6. Less need for trickle charging.
The shelf life of li-ion batteries is more than two years, which means that data centers don’t need to trickle charge the batteries during lengthy or protracted construction projects. During normal operations much less energy is used to maintain battery charge as well, reducing energy cost further.
7.Prioritizing safety
As with the use of any battery, safety has to be a top priority for data centers. Transitioning to li-ion batteries from VRLA brings with it important safety considerations.
