Just my opinion / experience : Optima Batteries as back up power source.
I had purchased 5 new yellow top Optima batteries (deep cycle) for my home ham
shack backup power system (thinking I was doing the smart thing). They were
quite expensive. I've always believed 'you get what you pay for'.

Does anyone out there know if the difference between a Model 38 and a Model 38A
is software only, or was there a hardware change (beyond EPROM, RAM -- stuff
involving the software) also?

Paul has some good points about batteries.
Here are a few more:
A so called marine deep cycle/starting battery is nothing more than a little
heavier starting battery.
A true deep cycle battery has much larger plates than a starting battery.
A starting battery has thinner plates which allows it
In 1999, after some research and finding that most small fleet vehicles in
Alaska use the Optima red top, I bought one. Temperatures vary from -22 to
+123 here, so I figured I'd have better luck with a battery which decline
ratings in a year excede the capabilities of a typical starting battery
Yes there were firmware and hardware circuit modifications and these are
documented in the manuals.
