Bob,
I used a big battery (AutoZone 35-DG for 1995 Toyota) in my Elite 173 RG and I am having to fly with 40 pounds
of ballast in the floor of the co-pilot seat due to W&B when I am flying by myself. The 173 wings are heavier
and all of this weight is behind the CG. My empty CG and weights are: 127.7 inches 1484 lbs.
(I chose this battery as it was a bit narrower and shorter than the GM battery suggested. I had to raise this
battery about 1.5 inches off of the battery shelf because the nose gear was hitting the battery when
retracted.)

I too have been putting some thought on batteries as I build my batter tray. I'd like some feedback on my
thoughts here...
I'm considering going with an auto battery which is sized for a honda civic. The battery is about 30-40%
smaller (and lighter) than what is called for in the manual (chevy battery, I think). But it can be had with
very close CCA spec's and obviously 12v. Because of this size, it is also much lighter which is a plus..
My only concern is the weight, without the weight of the battery, and I going to be running in a L&B issue
with a much lighter battery in the front?
Any comments?
bob

>>I want a primary battery for starting and the usual ... what do you think is the best with a 60 amp
alternator and 12 volt system?<<
Well, I used the highly scientific method of taking my battery tray to Wal-mart and finding the sealed
battery that fit the tray best.
>>Next, I want a back-up battery ... aren’t deep cycle best for these applications?<<
Are you using an auto-engine conversion? If you have a mag fired engine a backup battery is just wasted dead
weight. The Wal-mart battery that fits your tray will crank you engine for a long, long time (don't ask how I
know that :0 ) and more importantly it will run your avionics for a very long time. Longer than your fuel
supply will last. So why bother?
If you are using an auto engine then never mind, get the backup battery.
