I've been battery shopping lately. Most batteries at my local Walmart in central VA seem to be East Penn--no vent caps and the serial number starts with EP. The particular ones I looked at had date stickers from 12/20 to, oddly enough, 9/21.
For the size I need (35), the Maxx specs match the NAPA Legend/Deka 735MF. The mid-level was sold out.
However, the Value battery does not have a match in the NAPA or Deka catalogs, and said "Made in Mexico" beside the UPC barcode. The Maxx did not specify country of manufacture. Value specs were 500 CCA/625 CA, where the NAPA Proformer/Deka 535MF is 550/675.
FYI
