Deep-cycle gel batteries
Deep-cycle gel batteries are maintenance-free 12V/6V gel cells built for repeated deep discharge. This page maps mobile duty such as cleaning machines and wheelchairs; Ah is not selected until voltage and mounting are known. Code scanning lives on the models index. Stationary UPS backup belongs to AGM, photovoltaic storage to solar gel; flooded PzS forklifts are not selected here.

Applications
Technology
Built for mobile applications requiring repeated deep discharge — cleaning machines, wheelchairs and caravans — Nova's deep-cycle gel range spans 12 to 270 Ah. Unlike standard (SLI-type) starter batteries, deep-cycle cells are designed around routinely discharging and recharging a large share of their capacity; they are optimized for sustained, steady power delivery rather than short bursts of high current.
How it works
The gel electrolyte structure is built to recover after deep discharge; gas emission during use is minimal and no acid or water needs to be added. The plate construction is designed to resist active-material loss across repeated deep-discharge cycles better than a standard starter battery.
Construction
Gel electrolyte (VRLA) sealed type, built for deep-discharge cycling; capacity values are stated at the C10 discharge rate.
Limitations
- The charger must match the deep-cycle gel profile for full charge and expected service life.
- Adding water or acid is neither required nor recommended — the gel construction is sealed.
- A model cannot be recommended before the application's (mobility device, cleaning machine, etc.) voltage and physical mounting requirements are known.

Frequently asked questions
- Which duty does deep-cycle gel own?
- Repeated deep discharge on mobile equipment (cleaning machines, wheelchairs, access platforms). Stationary UPS backup belongs to AGM; photovoltaic storage belongs to solar gel.
- How does Deep-cycle gel batteries work, and what does the range cover?
- The gel electrolyte structure is built to recover after deep discharge; gas emission during use is minimal and no acid or water needs to be added. The plate construction is designed to resist active-material loss across repeated deep-discharge cycles better than a standard starter battery.
- Which duty classes is Deep-cycle gel batteries evaluated for?
- Floor cleaning machines Wheelchairs Caravans Personnel lifts Electric pallet trucks
- What is the difference between the Deep-cycle gel batteries family page and the models list?
- The Deep-cycle gel 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 Deep-cycle gel batteries?
- The charger must match the deep-cycle gel profile for full charge and expected service life. Adding water or acid is neither required nor recommended — the gel construction is sealed. A model cannot be recommended before the application's (mobility device, cleaning machine, etc.) voltage and physical mounting requirements are known.
