Who makes the batteries for Lexus ES350, and what are the warranties

 

I buy all batteries from Walmart. Only 3 year warranty out there and there are Walmarts everywhere in case you need a replacement.

Do you mean who makes batteries that will fit in a Lexus? All battery manufacturers and different warranties.

Or do you mean who makes the factory supplied batteries in your year and model? Probably that changes based on bids from manufacturers, but I don't know who they have been.

I think the original battery was Panasonic, made in Japan if I remember correctly. Replacement batteries are all the same, look for correct specification size and fresh manufacture dates.
