This is not to say that Optima or Cyclon are bad battteries.
It's to say that ham radio backup is not what they're designed
for. Both will make a really sweet home UPS system, and there
are some obvious advantages to a sealed design, not the least
being satisfying any spousal concerns over damage to "her"
carpet, etc. But you'll get more bang for your buck with a
battery designed to deliver more amp-hours over a longer period.

Ok, so what would you reccomend for a battery that sits indoors (but in a
battery box if need be) and would be on float most of the time, with deep
discharge at say C/10 or C/20-ish rates?



A sealed lead acid battery. Like in airplanes.

A sealed lead acid battery. Like in airplanes.

I suspect that having the word "aircraft" on the case will cost me dearly.

What would that equate to in terms of something I might find at battery
masters, or the inexpensive section of batteries plus?

I think a car stereo store
But the same technology is available without FAA approval ;^)

I would never use an aircraft battery for anything other than in an
aircraft. For weight savings aircraft everything is made as light as
possible consistent with safety and operation. Light weight and battery
capacity are completely at odds with each other.

The aircraft sealed lead acids and the ones at the car stereo store are
almost identical.
My point on a sealed battery has to do with hydrogen gas in a closed space.
