In *theory* the "standard" 7.5 AH battery will power your transponder for 8+
hours. Sealed Lead Acid batteries rarely achieve their advertised capacity in
ideal conditions even when new. Now age that battery for a year or two. Throw
in
some repeated deep discharges. Now cold soak the battery for a few hours at
altitude. I think you'll find that your 7.5 AH battery has something more like
4
AH (or less) useable capacity. So you up the size of the battery to 12 AH. Yes
you can always find somewhere to put the additional equipment. However a real
problem is that there are a significant number of ships out there that are at
(or over) their max. allowable weight for non-lifting parts, and the 10+ lbs
of
the additional battery and associated wiring is simply too much.
I think that ATC would much rather see you suddenly pop up on their radar
when
approaching airspace than suddenly dissappear (from a dead battery) while in
or
overflying their airspace.

I agree, but nevertheless am not sympathetic. You should load test your
batteries yearly. Get a new one if it's marginal. Lose some weight.
