Battery OEM Toyota or Duracell

I still prefer Duracell.

Toyota Prius, the battery isn't that big of a deal, the health can be checked with an app and a dongle, and they;re the most reliable cars on the planet.

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.

Pruis 12v battery last a long time. I just replaced my 11 year old battery. It was still working I just decided to do it as maintenance.

Assuming that it's a hybrid and not a PHEV it should run you about $2,500 to have it done professionally, or less than $1000 to do it yourself. At least that was my experience with my Prius.

FWIW…. I’ve had 3 Duracell batteries and all have died within 3 years of manufacture date, and they have a 2yr warranty.

I'm not putting a Duracell in my car, they can't even make a double A that doesn't leak within the year.
