BIGBULS Posted July 19, 2008 Report Share Posted July 19, 2008 I think Exide is the other manufacturer?? I do believe you are correct. Quote Link to comment Share on other sites More sharing options...
per0781 Posted July 19, 2008 Report Share Posted July 19, 2008 we've used ac delco batteries in every car we've owned with no problems X2 X3 Quote Link to comment Share on other sites More sharing options...
Canada Posted July 19, 2008 Report Share Posted July 19, 2008 In my experience, not so much the brand of battery.......more the TYPE of battery......side post verses top post. GM has been switching everything back over to top post batteries as new models come out. A side post battery just has a 3/8" nut brazed in with lead....so any amount of heat from extended periods of cranking will cause issues. Exide is the 3rd battery company......my dad works for them. They not only make their own line.....but also others.....Wal-Mart, John Deere, and also some BIG ones for the military...to name a few.

BXX Posted July 19, 2008 Report Share Posted July 19, 2008 You guys are forgetting something very important!!! Just because they are made by the same manufacturer doesnt mean the Duralast and AC Delco (for example) are the same. They are made to very different specifications. Grid design, anchor points, lead paste concentration, grid/plate configuration, solder/material quiality.. Quote Link to comment Share on other sites More sharing options...

Grid design, anchor points, lead paste concentration, grid/plate configuration, solder/material quiality.. Maybe that would depend on the manufacture. At the plant I picked batteries up from, for 3 years, the duralast batteries, delco batteries, and another manufacture, all came from the same assembly line. The only diference on the batteries was the case and connector points, since duralast wanted top and side post. I also picked up batteries from Johnson Controls in Iowa many times, where the 75 series batteries are made for Sears, and Energizer. Same assembly line again.

Canada Posted July 20, 2008 Report Share Posted July 20, 2008 Typically the only differences are if the grids are glued to the bottom of the case for a rough duty battery.....some add a salt tablet to the acid...helps with CCA. Other than minor changes....most are the same....at least as far as the manufacture is concerned. Exide also makes the O'Reilly's Super Start.
