I just bought one for my jeep one month ago, no trouble. Also have one in Cadillac ext for about two years and has been trouble free also. Don't know who manufactures them but sure most companies just put their own label on them and may just come from same distributor.

Hit and miss mostly. A few years ago when I was a tech they were absolute garbage after a year and often had bad cells. Lately it seems the quality has improved but im unsure of how much. Personally ive always been a Diehard/Mopar/Motorcraft guy but currently my Jeep enjoys a Caterpillar battery made by Deka which has yet to let me down. Both my Mustang and my gf's Focus ST still use the factory supplied Motorcraft battery and my dad just replaced his 1999 F-350's Factory battery with another Motorcraft. For what its worth stay far away from AC delco batteries. You wouldnt believe how many would come into our shop with acid spewing out of the side posts and breaking off from the battery with the cable still attached and they were less than 3 years old.

Walmart maxx batteries are made by johnson controls, the company that makes optima.
They were bested only by interstate in an independent test a few years ago. I used to install them in boats for certin customers of mine.
Just make sure it's a name brand and you should be just fine!

I currently work for waly word in the tle and the company who supplies currently is johnson controls. Like with everything mass produced we always get a percentage returned bad. One of the biggest issues with the batteries is to never ever let it die. If you think there is a issue with your charging system or some componet shorting out for gods sake unhook the battery asap. These batteries are very tempermental and if you let on fully drain you might as well write it off now. Ofcourse if you want a free replacement within the Maxx 3 year warrenty........
From my experience they are about as good as any, but far less expensive.
Watch out for Warranty tricks from Walmart. I had to replace one, but they did away with the 2 year and upped it to a 3 year with identical cranking specs. Of course it cost more than the 2 year warranty. When they tried to charge me more for the replacement, I said the sticker says free replacement and i asked to speak to the Manager. Well, the Manager said no problem. Basically don't take the first answer if you don't like it.
Problem with walmart is that they drive such a hard bargain with the supplier, and have such large contracts, that quality suffers. Companies are stressed to produce enough product and have it delivered or be in breach that they are willing to kill their reputation to avoid litigation. Net effect is that many things from walmart are a waste of money. Usually for me either the alternator kills the battery or a crappy battery kills the alternator. Otherwise I leave it alone.
