walmart sources batteries from 3 suppliers according to consumer reports
in nwpa/western ny-they are using exide maxx-start 94rn (white battery) for $75 730 CCA, and 875 CA
in eastern ohio-they are using johnson controls maxx-start 94r (black battery) same $75 but 930 CA
note: the 10/09 JC battery had a more modern looking blue maxxstart sticker on the front which said *2 year free replacement*. the 8/09, 9/09, and 11/09 JC batteries in the same rack had the older looking maxx start front stickers which said 3 year free replacement
exides have left me down numerous times. new batteries testing as bad cells, 3 month old batteries testing internal failure, and 1.5yr old batteries with buldging sides.
