VRLA vs LiFePO4 in a UPS

In most cases this is a battery swap rather than a redesign — matched to the UPS voltage and charge profile.

	VRLA string	LiFePO4 replacement
Cycle life	~500	2,000–5,000
Weight	Baseline	≈ 1/2
Recharge	Slow after an outage	Faster
Footprint	Full rack	Less for the same runtime
TCO	Replaced more often	Lower over the life

We confirm any BMS communication your UPS expects before the swap.

Runtime you actually get

Load	On 3 kWh	On 6 kWh
1 kW	~3 h	~6 h
3 kW	~1 h	~2 h
6 kW	~30 min	~1 h

What has to match

Voltage

Bank voltage matched exactly to the UPS string.

Charge profile

Charge window tuned to the UPS charger, BMS comms if required.

Monitoring

Health reporting to the UPS or your own BMS.

Overview

EGbatt UPS lithium solutions swap the valve-regulated lead-acid (VRLA) string in an uninterruptible power supply for a LiFePO4 bank tuned to the UPS’s charge window. The gains are concrete: 2,000–5,000 cycles vs ~500 for VRLA, roughly half the weight (easier rack load and handling), faster recharge after an event, and a smaller footprint for the same runtime. We match voltage and charge profile to the UPS and confirm any BMS communication it expects, so the swap is a battery change, not a redesign. Best for data, industrial and critical-commercial loads where battery TCO and footprint matter.

How to specify & buying guide

Match the LiFePO4 bank's voltage and charge window exactly to the UPS.
Confirm any BMS communication the UPS expects for health reporting.
Size runtime from the load and the seconds/minutes of bridge you need.
Compare TCO over the battery life, not just upfront cost, vs VRLA.

How EGbatt builds it

Solutions are where product lines meet an application — backup, off-grid, peak shaving or telecom. We specify the cell chemistry, capacity, inverter and controls as one system, then document the design so your team can deploy and service it.

Certifications & compliance

UN38.3 — Mandatory lithium battery transport test (altitude, thermal, vibration, shock, external short). Required for any cross-border shipment.
IEC62619 — International safety standard for industrial Li-ion cells and batteries; expected by EU and most APAC buyers.
UL1973 — North American safety standard for stationary lithium battery systems.
CE — EU declaration of conformity for the applicable directives.
RoHS — Restriction of hazardous substances in the battery and BMS.
IP65 — Dust-tight and low-pressure water-jet resistant — suitable for outdoor enclosures.

Frequently asked questions

Can it replace my VRLA?

Yes, matched to the UPS voltage and charge profile — often a battery swap, not a redesign.

How much longer?

2,000–5,000 cycles vs ~500 for VRLA.

Is it lighter?

Roughly half the weight, easier on the rack and to handle.

Does it recharge faster?

Yes, shorter exposure window after an outage.
