It won't hurt your battery to leave it partly or completely discharged,
mainly because it is a single cell, and there is no risk of cell reversal
during discharge as is the case in a battery pack. Nickel cadmiums and nickel
metal hydrides are similar in this respect.
The following link includes storage recommendations by several different
manufacturers for several different battery chemistries.

I installed a Nicro 4 inch solar vent in Alianna this past summer. It
seemed to run 24/7 all summer long after I turned it on following 3 days of
initial charging in bright sunlight. I was at the boat yesterday afternoon and
noticed that the fan had stopped. We have had a fair bit of dull rainy weather
around here lately and of course daylight hours have decreased considerably as
the seasons changed so I expect there was not enough sunlight to keep the
battery fully charged. I had hoped that the fan would run all winter long to
keep the air inside the boat fresh during layup so I intentionally modified my
tarp to allow full access of the collectors to the daylight sun and I left the
fan in the on position. Better interior ventialtion during winter storage was
one of the main reason that I installed this solar vent but now there does not
seem to be enough light to keep the cells fully charged. I am wondering if
leaving the vent in the "on" position to use up whatever level of charge it
aquires under such conditions may be doing long term damage to the recahrgeable
battery and I wonder if I should keep it turned off during winter storage. Any
advice appreciated. Thanks

Jim,
Is it still running at 5 or 6 am? That's important because that's when I
think the highest potential for condensation is.

Dennis,
The Tenergy brand have a good reputation with the R/C crowd. I would
recommend sticking to NiCd type batteries for this application. They have a
lower capacity than NiMH but usually hold up much better. Tenergy makes a
3500mAh C-cell. A good source for quality batteries is your local hobby shop
(one that deals with R/C planes, not a chain type hobby store). The
rechargeable batteries you typically find at chain stores are low quality junk
and more expensive to boot!

The battery on my new style Nicro solar vent finally died (Nicro
model N20703S). Seemed to last the 3-5 years in Nicro's literature.
The manual states at least 2800 mAh C cell is needed. I replaced it
with a Nuon 3000 mAh C cell from a local battery store. Now I'm researching
them and find Nuon batteries don't get good reviews.
Be interested in hearing listers experiences with other brands.
Other brands are Powerizer, Tenergy, GLE, etc. Note: Must be minimum 2800
MaH. (For example: Energizers are only 2500).
I'm assuming that less than 2800 would work but wouldn't work well in
winter. Short days, long nights and cold temps would probably cause energy to
run out in the wee hours.
FYI: Changing the battery in the new style Nicro vents is a PIA.
After you remove the 3 mounting screws, you have carefully pry the solar panels
up to reveal the battery and change it. Flexing the panel is likely to crack
it.
