Sealed AGM batteries
Sealed AGM batteries absorb sulfuric acid into a glass-fibre mat (Absorbed Glass Mat) in valve-regulated (VRLA) 12V lead-acid construction. This page maps Nova’s AGM range for UPS, security and lighting backup. Capacity is not recommended until load power and backup runtime are known. Code scanning lives on the models index. Flooded PzS, solar partial-state-of-charge storage and start-stop OEM fitment are not this family.

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 commercial name “dry type” labels this sealed AGM range; electrolyte is held in the glass mat and water or acid is not added. 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.
- Flooded PzS traction, solar partial-state-of-charge storage and start-stop OEM fitment are not this family.

Frequently asked questions
- When is sealed AGM chosen instead of gel or traction?
- AGM is the sealed VRLA backup-power family (UPS, security, lighting). Cyclic mobile gel and flooded PzS traction are separate families. Capacity is not recommended until load power and backup runtime are known.
- 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. Flooded PzS traction, solar partial-state-of-charge storage and start-stop OEM fitment are not this family.
