Why Choose a 72V 28.8Ah UPS Lithium Battery for Data Centers?

Modern data centers demand compact, efficient, and future-ready energy solutions — and the 72V 28.8Ah UPS Lithium Battery delivers on all fronts. When integrated into your UPS systems, this Li-ion battery offers significant engineering, operational, and commercial advantages over traditional VRLA solutions:

Smaller Footprint, Bigger Possibilities

The 72V 28.8Ah UPS Lithium Battery offers a much smaller footprint — occupying 50–80% less floor space than lead-acid batteries. This space-saving design is critical in high-cost or restricted environments. Its lightweight structure simplifies UPS installation and gives you more flexibility in rack layout and cooling design.

Superior Performance & Versatility

Unlike VRLA batteries with only ~500 cycles, the 72V 28.8Ah UPS Li-ion battery delivers thousands of charge/discharge cycles, making it highly reliable for mission-critical systems. Its faster recharge times and high-rate output enable it to support not just backup power, but also advanced UPS applications such as:

Peak shaving
Load balancing
Grid-interactive UPS systems
Process control support in industrial environments

Sustainability & Second Life Value

Although lithium-ion recycling is still evolving, the 72V 28.8Ah LiFePO4 UPS battery offers environmental advantages by enjoying a second life as an energy storage component. After its first service life, it can be reused in residential or grid-scale energy storage systems, helping to reduce peak demand and support renewable energy integration.

Lower Total Cost of Ownership (TCO)

Despite higher upfront costs, the 72V 28.8Ah UPS lithium battery is more economical over its lifecycle. Benefits include:

4–5x longer lifespan

Reduced replacement and maintenance costs
Ability to operate at higher ambient temperatures, reducing HVAC energy usage
Decreasing global Li-ion battery prices mean more value per kWh stored

Together, these factors result in significant CapEx and OpEx savings — ideal for data center operators aiming to optimize ROI.

Conclusion

From compact design and enhanced lifecycle to smarter energy usage and sustainability, the 72V 28.8Ah UPS Lithium Battery is built for the next generation of high-efficiency, space-constrained, and performance-critical data center environments. If you’re upgrading your UPS infrastructure, this is the smarter, long-term choice.

Is EGbatt a Lithium Battery manufacturer?

Yes. EGbatt is a manufacturer located in Shenzhen, Guangdong, China. It designs and produces LiFePO4 battery packs for energy storage, electric forklifts, marine applications, golf carts, RVs, and UPS systems.

What is the production lead time?

Based on automated production technology, the current product lead time is 15-25 days.

Which battery cells does EGbatt use?

The company has strategic cooperation agreements with top manufacturers like EVE and REPT, and insists on using A+ tier One lithium iron phosphate cells for its solar batteries.

Which inverters are compatible with EGbatt batteries?

For 48V inverters, compatible brands include Victron Energy, Goodwe, Studer, Solis, LuxPower, and others. For high-voltage three-phase inverters, compatible brands include Atess, Solinteg, SAJ, Goodwe, and Solis.

What is the warranty for EGbatt energy storage batteries?

EGbatt offers dealer customers a 10-year warranty and technical service for its energy storage battery products.

What is Depth of Discharge (DoD)?

DoD describes how much of the battery's capacity has been used. A DoD of 100% means the battery is completely empty, while 0% means it is full.

What is State of Charge (SoC)?

SoC reflects the battery's charge level. A SoC of 100% means the battery is full, and 0% means it is empty.

What is C-rate?

C-rate, or power factor, indicates how quickly a battery can be charged or discharged relative to its capacity. A rating of 1C means the battery can be fully charged or discharged in one hour.

What is the cycle life of a EGbatt Lithium Solar Battery?

The battery uses Lithium Iron Phosphate chemistry and provides a cycle life of over 6,000 cycles at 90% Depth of Discharge, and over 10 years at one cycle per day.

What is the difference between kW and kWh?

kW (kilowatt) is a unit of power, measuring the rate of energy production or consumption. kWh (kilowatt-hour) is a unit of energy, measuring the total amount of work done or energy used over time.

Where can a home battery be installed?

EGbatt home batteries are suitable for both indoor and outdoor installation (depending on the model's protection level) and offer floor-standing or wall-mounted options. Common locations include garages, attics, or under eaves.

How long can a 10kWh Powerwall run home appliances during a power outage?

This depends on the load. As a realistic example, a 10kWh battery could run ten 100-watt light bulbs for 12 hours without recharging.

How many home batteries does my house need?

The number varies based on home size, energy consumption history, and personal goals (like which devices to run during an outage). For most systems, 2 or 3 batteries are installed. A detailed discussion of your needs is recommended for an accurate assessment.

Can I go completely off-grid with solar and batteries?

Yes, it is possible, but it requires careful planning and significant investment. A true off-grid system needs a large enough solar array and sufficient battery storage to sustain your lifestyle. Cost and having an alternative energy source for when solar charging isn't possible are key considerations.

Is EGbatt an online store?

No. EGbatt focuses on building long-term relationships with business partners like battery distributors, solar equipment dealers, and installation contractors worldwide, not direct sales to end consumers.
