Why the right battery choice is critical for data center uptime
Not every part of a data center places the same demand on a battery. Central UPS systems, high-power IT loads, rack-level backup, network rooms and remote edge sites all require different balances of float life, discharge power, serviceability and footprint. Specifying one battery type for every duty can lead to oversizing, unnecessary replacements or compromises in performance.
Power-Sonic’s Network Power portfolio helps you select the right technology for the right job.
- Protect uptime with proven performance in float and high-rate discharge conditions
- Optimise footprint with high energy and power density for space-constrained installations
- Reduce lifecycle cost with long design life and fewer replacement cycles
- Simplify maintenance with sealed, maintenance-free AGM and front-access options
- Standardise across projects using a coordinated, multi-platform network power portfolio
One portfolio. Four battery platforms. Complete data center coverage.
Rather than forcing one battery platform to do everything, Power-Sonic offers four complementary series that can be matched to specific layers of your data center power architecture.
PL Series. Pure Lead Long Standby Life.
For long-life float service in central infrastructure and supporting DC systems
The benchmark in float service reliability. Extended design life and stable standby performance minimise costly replacements and support uptime in critical applications. PL is ideal where batteries spend most of their life on float but still need to deliver dependable backup when required.
Best suited to:
- Long-duration standby requirements
- Control power
- Protection relays
- Monitoring systems
- Auxiliary DC systems

PLHR Series. Pure Lead High Rate.
For mission-critical UPS and high-power discharge on demand
Purpose-built for instant energy delivery. High discharge rates, rapid recharge recovery and superior power density make PLHR the clear choice for demanding UPS environments where autonomy is short but power demand is high. For many data center UPS installations, this is the lead series.
Best suited to:
- Central UPS
- Distributed UPS
- White space support
- Critical IT loads
- Switchgear
- High-current backup events

PGFT Series. Front Terminal AGM.
For rack-mount UPS, network rooms and edge sites
Front terminal AGM engineered for space-efficient rack installations. Compact footprints, easy front access and a 10–12 year design life make PGFT a practical choice for rack-mounted UPS, network equipment and edge data center backup where serviceability is a major priority.
Best suited to:
- Rack-level UPS
- IDF/MDF rooms
- Network cabinets
- Distributed IT environments
- Edge facilities

PHR Series. High-Rate AGM.
For compact UPS and cost-effective high-rate backup
High-rate AGM designed for rapid discharge performance in standard 12V monobloc formats. With low internal resistance, strong power density and broad size coverage, PHR is a cost-effective option for smaller UPS systems, auxiliary backup and cabinet-level deployments where fast power delivery matters.
Best suited to:
- Smaller UPS cabinets
- Distributed critical loads
- Security and monitoring backup
- Cost-sensitive edge or micro data center deployments

Choosing the right battery for each layer of your data center
Different parts of a data center have different backup requirements. Power-Sonic’s brochure helps you map the right series to each layer of your power strategy.
Click on a layer to see our recommendations:
Data center UPS (central and distributed)
PLHR is the strongest fit where long standby life, stable float performance and high-rate discharge all matter. It combines extended design life with the fast power delivery required for UPS events.
High-power UPS for critical IT loads
PLHR supports very high discharge currents, short autonomy windows and rapid recharge between events, ideal for demanding, high-density UPS environments.
Rack-mount UPS in white space and network rooms
PGFT’s front terminal design simplifies installation, inspection and replacement in racks, while PLHR front-terminal variants can support more demanding high-rate duties.
Control, monitoring and security systems
PL, PGFT and PHR each have a role here depending on the installation format and discharge profile, from long-life float duty to compact high-rate backup.
Edge, micro and remote data centers
PGFT suits rack deployments, PHR fits compact cabinet UPS, and PLHR supports locations where the highest-rate performance is required.

FAQ’s
Frequently asked questions about data center batteries
What batteries are used in data centers?
Data centers typically use standby and UPS battery systems designed to support critical loads during mains failure or power disturbance. Depending on the application, this can include long-life float batteries, high-rate UPS batteries, front terminal AGM batteries for racks, and compact high-rate monoblocs for smaller distributed loads.
What is the difference between float life and high-rate performance?
Float life refers to how well a battery performs over long periods on standby charge, while high-rate performance refers to how effectively it can deliver large bursts of power over short discharge windows. Data centers often need both, depending on the application layer.
Are front terminal batteries good for rack-mounted UPS?
Yes. Front terminal AGM batteries are well suited to rack-mounted UPS and network room applications because they simplify installation, inspection and replacement in space-constrained rack environments.
Which Power-Sonic range is best for data center UPS?
For many central and distributed UPS applications, the PLHR range is the strongest fit due to its high-rate discharge performance and long design life. Other ranges such as PGFT, PL and PHR support different layers of the wider data center architecture.
