Battery (Page 2/2) theogre DEC 02, 12:31 PM Bad news... Johnson Controls completes sale of its battery business last spring. I missed that. https://www.jsonline.com/st...-company/3638011002/ I finally found an easy list of band vs made by... https://www.cartechbooks.com/techtips/battery/ Your Costco is JC now called Clarios Says Exide and JC made Sears and Walmart. I use WM Maxx not the value ones. fierce_gt DEC 02, 02:48 PM quote Originally posted by olejoedad: I will never buy another OPTIMA i'd be leery about buying one now, very expensive and i'm not confident with the new ones. but, to be fair, i did have one that was remarkable(not in my fiero) and i transferred it into three different vehicles before I no longer had one that could fit it. i had two 'smaller' red tops before getting the 'big one' that really sucked though. My alarm would 'kill' a battery in about 3days if i didn't run the car and re-charge it. Was hoping the optima's would handle this better, but they did not. nowadays i tend to stick with costco batteries. they seem to be about as good as any other, and i don't have to spend over $200 for one olejoedad DEC 02, 02:59 PM I put an Optima in my V8 Formula in 2010. It lasted until 2016. The replacement was very expensive and is junk already. Always stored inside during the cold season. I wouldnt pay 50¢ for one. sledcaddie DEC 06, 03:35 PM Isn't a main advantage of an AGM battery in a Fiero is that they can't boil over and eat away the battery box? Spadesluck DEC 08, 01:44 AM I have a Dyna-Batt in mine (fieroguru uses one with his LS4). I have not had any problems with it at all. I have only had it a few months but I want to say fieroguru has used his for 3 years now.

Honestly most batteries seem to have a shorter life span anymore. Whereas i could go about 5 years before replacing a battery and now it seems around 3 I am replacing them. Could just be me though. Larryinkc DEC 08, 09:14 AM I use a Duracell AGM from Sams Club in my daily driver. It was still good but I replaced it at 8 years because I was going on an extended road trip and didn't want to take the chance having any battery problems during the trip. I use Odyessy AGM batteries in my Fiero and motorcycles and usually get at least 8 years service from them also. I charge the Odyessy batteries once a month during the off season with an Odyessy charger to maintain them.
