How long does an OPzS stationary battery last?

20 to 25 years at 20 °C in float, provided the electrolyte level is maintained and ambient temperature stays stable.

What's the difference between OPzS and OPzV?

OPzS uses liquid electrolyte and needs maintenance (water top-ups); OPzV uses sealed gel, needs no maintenance but has a somewhat shorter life (18-22 years).

Is a stationary battery compatible with any UPS or remote-control installation?

Yes, as long as the cell-bank voltage and the minimum capacity (Ah) required by the equipment are respected; the 2V cell format is an industry standard.

Why choose industrial AGM over OPzS?

Because it's sealed, needs no maintenance and mounts in any orientation, though its service life (10-12 years) is shorter than a well-maintained OPzS.

During the week of August 17th to August 21st, orders will only be processed from 9:00 AM to 1:30 PM, including urgent orders until 2:00 PM.

Stationary Batteries

Stationary batteries are built for systems that demand a very long service life (10-25 years) working in float: telecoms, remote control, electrical substations, industrial alarms, control instrumentation and high-power UPS/standby systems in data centres and hospitals.

Three technologies cover different needs: OPzS (flooded tubular lead-acid, 20-25 years), OPzV (sealed gel tubular, 18-22 years) and sealed industrial AGM standby (10-12 years). All optimised for slow, deep discharge with minimal self-discharge — the reference standby battery for UPS and telecom backup.

OPzS vs OPzV vs stationary AGM: which to choose

OPzS is the gold-standard stationary battery: thick tubular plates, liquid electrolyte, transparent cells with a level gauge. 20-25 year life at 20 °C, needing water top-ups every 1-3 years. OPzV is the sealed gel version — maintenance-free, 18-22 year life, ideal for unventilated technical rooms. Industrial AGM is the entry point to the stationary range: 10-12 year life, sealed, mountable in any orientation, the most common standby battery for lower-power UPS.

Typical stationary battery applications

Telecoms and phone masts — hours of backup during a mains outage.
Electrical substations and remote control — breaker start-up and SCADA systems.
UPS for data centres and hospitals — highly reliable standby backup with low self-discharge.
Industrial alarms and instrumentation for continuous process control.

How to choose between OPzS, OPzV and AGM

It depends on whether the installation allows periodic maintenance — OPzS then gives the longest life at the lowest cost per year — or needs to be sealed and maintenance-free — OPzV or industrial AGM. Space also matters: OPzV and AGM can go in rooms without forced ventilation thanks to their very low gas emission.
