Do car battery warranties reflect actual physical differences?
Do car battery warranties reflect actual physical differences?
For my particular car, Walmart seems to sell batteries with 1 year, 2 year, and 3 year warranties. ~$70 for the 1 year, ~$110 for the 2 year, and ~$150 for the 3 year. Are these batteries actually different? If the battery with the 3 year warranty actually lasts 3x longer than the battery with a 1 year warranty, I guess it'd be the better deal, but I'm suspicious if they're actually much different.
It looks like batteries at most other stores are even more expensive with the same warranties.
