PA28 Battery replacement

Do you have copper battery cables? My Warrior would disengage the gear like
you described until I got the copper cables put in.

Hey all. I'm pretty certain I've convinced myself that my "bad starter"
and/or bad ring gear are actually my battery going bad. With the skytec
starter, it
makes sense that at high-load, the voltage could drop enough so the
starter solenoid
cannot hold the gear engaged to the flywheel. It pops back out while
cranking on a
compression stroke.

So, what are the thoughts on the different batteries? I'm pretty sure
mine is
the old Gill G35. It's been in there for at least 3.5 years. Any good
replacement
ones that might save weight, etc? FWIW it's a 180hp O-360 so it is high
compression.

Thanks
-Cory

Yes, I've got the copper cables. I've checked the terminals and connections
and they all seem to be in good shape. Looks can be deceiving however, so I'm
planning on going out with an assistant and a voltmeter and track down all the voltage
drops.

With the Skytec starter, I never really had a problem with "cranking power."
It's only the gear disengaging now that's making me suspect. If it turns out it is
the battery and I replace it, I suspect I'll be surprised at how much *extra* cranking
power I'll have. As things slowly degrade you forget what it used to do.

The main reason I'm asking is because another friend of mine put a lightweight
battery in his experimental. I don't know if it's available for certified.
