Delphi sold the Delco battery brand name and manufacturing plant to Johnson Controls in 2005-2006. It wasn't a bankruptcy sale.

Sncfrin is 100% correct at least today, but not all plates are the same. Delco used to have a different process whereby they would cast the plates and then stretch them forming what looked like expanded metal with little diamond shaped spaces. Of course they went bankrupt and sold all their equipment to China so I doubt anybody is still using their inferior system today.
As far as Interstate is concerned they are indeed a "Battery Specialist" and not a manufacturer... well almost, anyway. A few years ago Interstate Batteries purchased part interest in BESA (Battery Enterprises of South America) and started importing batteries from Mexico. When you buy a battery today it pretty much takes an expert to ID the maker or even the country where they are made. And yes, Johnson Controls makes batteries for Interstate and also Wal-Mart. Exide made Wally's batteries for several years as well as for Sears and their CEO went to the Federal Penitentiary over the Sears deal.

What about the Duracell agm battery
Good battery?.....They are 114.00 at sams.....with a 18 month replacement...the regular flood cell is 94.00..with 12 month replacement
Not bad if you need the AGM. Gives you better tolerance of not recharging and it will probably have longer life.
Is it a recommended practice to leave a trickle charge on the batteries all the time when not in use?
A trickle charegr is generally a constant current 2A charger. Not good for the battery.
What you want on the battery all the time is a float charger or a charger that automatically cycles off then checks the battery periodically. All onboard chargers are either float chargers or cycle on and off.
I'm probably in the minority, but I've had great service out of the Maxx batteries at Wal Mart.
