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 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.
