Battery AC DELCO or Duracell

AC Delco was good.. lasted 2 years in my old car

I started buying AC Delco, probably now made in Korea. Anyway, 9 years in my Kia Spectra, 7 years in our rarely driven ‘02 Accord, has another in there from a year or two ago. One that was in my wrecked Cobalt, still works but is sitting. Now one for the Cavalier that had a two year old premium Everstart. The place I get the AC Delco batteries from sells a lot of them so they refresh their inventory. And they are also cheap with my business account. Was $120 for the last one, got the better option they offer. But most have been under $90. Although prices have gone up everywhere throughout various product. Just saying, for whatever reason they have been the only ones I didn’t have to warranty out every 2-3 years. Maybe I’m just getting lucky with them for the last 12-13 years. But I got tired of SuperStart and Everstart batteries that I used to go for. Duracell had been good in customer vehicles.

I've had good results from East Penn Duracell at Sam's Club. I just replaced one nearly 8 years old.

The best way to check is to go with a multimeter and get the highest voltage/closest manufactured date. Duracell might just be EverStart rebranded BUT NO the Walmart battery will last around 1-2 years, maybe less. If you want to make sure your covered with a good battery, that’s when you go to Advance Auto or AutoZone and get the battery with 3 years of warranty and swap it out right before the 3rd year ends and I find the batteries last me forever.

The best lead acid type of battery is a Duracell/East Penn hybrid/house AGM deep cell. These have thicker plates and are typically used for RVs and boats. They can tolerate deeper discharge and are less susceptible to damage (AGM). They sacrifice a little instantaneous current output, but that's not needed on an EV.

We’ve always had luck with Duracell in our cars.

I’ve replaced several Duracell batteries recently that had been recently installed within the last few month. We’ve had good luck with power sonic, yusa, and first power.

Power Sonic or Yuasa. Duracell is great for lots of service every year after an inspection. Never seen them make it to the next inspection alive.

My company uses Duracells. Do not recommend

Worst batteries I've ever had the misfortune to buy. Both died within the space of 3 months and wouldn't put out any power whatsoever. No matter if I tried to charge them, it made no difference.
