I've been using Walmart for all my batteries with very good success.
Please don't hate me.




Same here, the yellow ones. The ones I've bought (2 years ago being the latest) have said "Johnson Controls" on the label.




I saw a post last year from a Johnson Controls employee( I think he was an engineer but not sure). He said that they make batteries for a lot of different venders. He said they all have the same exact plates in them but not the same number of plates. He said the Walmart batteries have the same quality of parts as any of their other batteries but they have the least number of plates. Weigh a Walmart battery and weigh the most expensive battery you can find that is made by Johnson Controls and I think you will see a significant difference.


In theory, there is no difference between theory and practice. In practice, there is.
