Applications
Technology
Nova's AGM range serves backup-power applications — UPS, lighting, alarm/security and elevators — in a valve-regulated (VRLA) sealed construction, spanning 5 to 200 Ah. The "dry-charged" designation refers to the cell being stored without electrolyte until commissioning, an advantage for long-term stock and shipping. Capacity selection is driven by the total load (W) to be backed up and the required backup runtime; a recommendation cannot be made before both are known.
How it works
Electrolyte is absorbed into a fiberglass mat (Absorbed Glass Mat) rather than held as free liquid, which minimizes gas emission during use and removes the need to add acid or water. The VRLA (valve-regulated) design includes a valve that vents gas safely once internal pressure crosses a set threshold; under normal use the valve stays closed.
Construction
Valve-regulated lead-acid (VRLA) sealed type; capacity values are stated at the C10 discharge rate.
Limitations
- Before commissioning, the storage area must be cool, dry and protected against terminal short-circuit.
- The charger must be set to a voltage profile matching VRLA/AGM chemistry; an incorrect profile can cause premature ageing.
- Adding water or acid is neither required nor recommended — the VRLA construction is sealed.

Frequently asked questions
- What is the difference between dry-charged AGM and gel batteries?
- The two technologies differ in construction and how they hold electrolyte; the right choice depends on application conditions, installation environment and maintenance preference. Share your application details with the technical team for a specific recommendation.
- How does Sealed AGM batteries work, and what does the range cover?
- Electrolyte is absorbed into a fiberglass mat (Absorbed Glass Mat) rather than held as free liquid, which minimizes gas emission during use and removes the need to add acid or water. The VRLA (valve-regulated) design includes a valve that vents gas safely once internal pressure crosses a set threshold; under normal use the valve stays closed.
- Which duty classes is Sealed AGM batteries evaluated for?
- UPS (uninterruptible power supplies) Elevators Alarm and security systems Lighting systems Electric toy vehicles
- What is the difference between the Sealed AGM batteries family page and the models list?
- The Sealed AGM batteries family page explains the chemistry/construction class and the range map. Every model code, series group and technical row lives on that family's /models catalogue; exact dimensions and capacity are confirmed there and on series/SKU pages.
- What limits apply when specifying Sealed AGM batteries?
- Before commissioning, the storage area must be cool, dry and protected against terminal short-circuit. The charger must be set to a voltage profile matching VRLA/AGM chemistry; an incorrect profile can cause premature ageing. Adding water or acid is neither required nor recommended — the VRLA construction is sealed.
