Because it is also the electrical system back-up. My PA-32's type certificate
calls out a 35Ah battery (I forget the brand). At the time it was
manufactured, there was no such thing as sealed or RG aircraft batteries.
Having the RG35AXC in there is extra peace of mind, and saves considerably on
the maintenance dollars as well. FWIW, the battery is more expensive to
purchase, but so far it has lasted nearly twice as long as the flooded cell
batteries had. Between that battery, the Bogert cables and the Skytec
starter, I could probably taxi my Cherokee Six with the starter. It spins
that fast.

Hmmm,,, Why a 35 amp in a single? I have the Concorde RG35 in a twin with
long cables to the engines aluminum even and it turns the prop like the
engine is already running...
Plus, the 25 amp RG Concorde battery will out power a standard 35 amp
battery by a significant margin.. For a Lane (owned one for a decade) the
RG25 will do the job and then some...

I am considering one for my 182. What do you have to do to the battery
box and what is the difference in weight?

I got an RG35AXC in my Skylane earlier this year. Piece of cake to
install, there's a small mod needed to the battery box lid, requiring
a highly specialized tool (a utility knife). The battery is STC'd for
various airframes, the STC paperwork was available from Concorde free
of charge.

I needed the involvement of an IA because of the STC issue, but
further replacements can be done by myself.

They're maintenance free, and they're not venting corrosive
fumes. They're a little more expensive than flooded cells, but in
AMU's, the difference is a pittance.

Go for it.
