While the “set and forget” nature of the Eaton 9PX lithium-ion UPS is appealing there is much more one can do other than just plugging things into it and going on vacation, though that’s an option. Eaton actually has several management options. The three main ones are Intelligent Power Management (IPM), Visual Power Manager (VPM), and PredictPulse Insight that belong to the Eaton Brightlayer Data Centers suite.
There is no single ‘best’ UPS battery technology; each approach has its own strengths and weaknesses, and it is up to each data centre operator to choose the one that best meets their requirements. The information below outlines the 3 main types of UPS batteries and their features. Lead-Acid UPS Battery Why are lead acid batteries used in UPS? Almost everyone with a mobile phone has become accustomed to the features and benefits offered by lithium-ion battery sets. Older handsets are often sold-on to the second-user market and if a battery requires recycling it is important to place this in the correct waste stream and to consider the battery as general waste. Conduit landing kit: This top-mounted landing kit is installed by the contractor and contains terminals for both DC power and control/status communications wiring. The installation instructions are provided, document part # P-164000742. Remote trip of the battery cabinet breaker: note that the UPS does NOT generate the shunt trip command for battery breakers (a UPS "load off" or UPS EPO command will shut off the UPS but will not trip the battery breakers in the LG cabinets). The user is responsible for providing +24VDC wiring to each LG cabinet to facilitate a remote shunt trip of the battery cabinet breaker. See the installation manual and the customer drawing #110000683 for details of this connection. PredictPulse Insight is a cloud-based remote monitoring and predictive analytics service. Like the above, PredictPulse can predict potential failures and allow users to proactively replace the devices and avoid unscheduled downtime. Subscribing to the service means Eaton is keeping an eye on the devices and admins can worry about other things. And if you can schedule downtime, users can save on costs and downtime in the future.The key difference between a lithium-ion battery and a lead-acid battery is the mix of chemicals used in the electrodes and electrolyte within the battery. Lithium-ion batteries use a metal oxide for the cathode, and a carbon-based material for the anode. The electrolyte is a lithium salt dissolved in an organic solvent. Life Span: The average life span of a VRLA battery is 4-6 years in ideal conditions. N1C Li-Ion battery life span is 10-15 year in nearly all conditions. Long life
LA UPS batteries use an electrolyte comprising water and sulphuric acid, and plates made up of sponge lead (negative electrode) and lead oxide (positive). The two main LA uninterruptible power supply battery types are VRLA (valve-regulated lead-acid) also known as ‘sealed’ or ‘maintenance-free’ and flooded LA batteries, also called ‘vented’ or ‘open’. Valve-Regulated Lead-Acid UPS Battery (VRLA) The Agents tab links the software agents of multiple devices to allow for a graceful shutdown over IP. In the event of a Power outage, Agents can automatically shut down non-critical equipment to extend battery runtime. Additionally, you can set agents to shut down all equipment as the battery is nearing the end of its runtime. A single cabinet configuration of 34.6 kWh comprises one switchgear, one switched mode power supply (SMPS) and 17 battery modules. They provide a longer lifespan and higher reliability than sealed LA batteries. LA battery rooms must be kept at a reasonably constant temperature (20 -25°C) to avoid reducing service life or even causing damage. Lithium-Ion UPS Batteries
How do I choose a UPS Battery?
Refresh charge to ensure all batteries in each string are properly voltage-balanced and within limits (this may require several hours of charging). Note that batteries will have been reduced to 30 percent SOC during shipment.
That's where an uninterruptible power supply (UPS) comes in. Its main function is to act as a big battery that powers your devices when your electricity goes out. They range from small units that can sustain a few low-power devices to big house units for entire homes.However, li-ion systems are more sensitive to charging and discharging methods. Most of these batteries include a battery management system (BMS) to protect against short circuits and overcharging. Charge and Recharge Efficiency: N1C Lithium Ion batteries can be charged/ discharged over 1000 times versus 200-400 charges/ discharges for standard VRLA batteries. N1C Lithium UPS units include built in chargers capable of 1-hour recharge times, compared to 4-10 hour recharge times of VRLA battery UPS systems. Smaller Footprint: A smaller footprint translates to reduced cooling requirements as well as about a two thirds reduction in weight. This offers the installation flexibility needed by many IT departments. This gets right to the crux of choosing the Eaton 9PX lithium-ion UPS over the lead-acid version. While you will pay more upfront, the lithium-ion battery can last two to three times as long. The lithium-ion battery can run longer and it is roughly 20% lighter. On top of that, it comes with a 5-year warranty versus the 2-year warranty of the lead-acid version. The 9PX6K-L fits in a 3U chassis sitting at about 81.2 Pounds (VS 106lbs from its Lead Acid counterpart) and measures 5.12″x 17.33″x 28.43″. Eaton offers several options for mounting this unit—the Lithium 9PX ships with a 4-post rail kit and feet for a tower configuration. Eaton also offers a 2-post rail kit that is sold separately.
