Applications

Technology

Nova's marine gel range delivers vibration-resistant deep-discharge performance for boat and yacht applications, spanning 40 to 800 Ah. On board, a battery often serves both engine starting and underway house-load duty (electronics/lighting); that dual role calls for a construction that tolerates deep discharge.

How it works

The gel electrolyte structure resists vibration and marine conditions; gas emission during use is minimal and no acid or water needs to be added. Because the electrolyte is fixed in gel form, it offers an added advantage over flooded types under the continuous motion and heel conditions a moving boat produces.

Construction

Gel electrolyte (VRLA) sealed type, vibration-resistant deep-discharge construction; capacity values are stated at the C10 discharge rate.

Limitations

  • The charger must use a gel/VRLA-compatible profile; on board, the alternator regulator should also be confirmed compatible with that profile.
  • Adding water or acid is neither required nor recommended — the gel construction is sealed.
  • Starting and house-load needs can differ; whether one battery can serve both roles should be assessed per application.

Frequently asked questions

Are marine gel batteries resistant to vibration?
The gel electrolyte reduces leak risk and adds resilience against the sustained vibration and motion found aboard marine vessels, compared with stationary-duty batteries.
How does Marine gel batteries work, and what does the range cover?
The gel electrolyte structure resists vibration and marine conditions; gas emission during use is minimal and no acid or water needs to be added. Because the electrolyte is fixed in gel form, it offers an added advantage over flooded types under the continuous motion and heel conditions a moving boat produces.
Which duty classes is Marine gel batteries evaluated for?
Boats and yachts
What is the difference between the Marine gel batteries family page and the models list?
The Marine 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 Marine gel batteries?
The charger must use a gel/VRLA-compatible profile; on board, the alternator regulator should also be confirmed compatible with that profile. Adding water or acid is neither required nor recommended — the gel construction is sealed. Starting and house-load needs can differ; whether one battery can serve both roles should be assessed per application.
