For years I have taken the trouble to find Delco batteries for my GM cars. Used to be you could get them at any auto parts store, but now they all have their own brands to push and Delcos are harder to find. Also, I don't really know if they are all that good anymore. I hear a lot about Interstate, but they seem to be sold mostly at garages. The battery currently in my 95 Park Ave. is an "Energizer" from Pep Boys, which is supposedly a 5 year battery but showing signs of weakness after only 2 years when it was installed as a warranty replacement after only 3 years.
So, what's the word on the street? Is any battery brand worth chasing down, or is it just a matter of "renting one" from among the private-branded bunch?
