Warning, Spiel ahead
I'm getting real tired of dealing with phucking batteries. The Blazer has had four batteries over the last two years, Had to put two sets in the Cummins already, and I've been messing with it for a month. And now my mom's 04 Trailblazer needs a battery. The silver half ton Dodge has a 6 year old Wal-Mart Whatever-start battery in it, and it's still going strong, Knock on wood. When I pulled the Cummins out of the weeds it still had a pair of Interstate Mega-trons in it that were marked as having been sold in 2002. They would still turn the over fairly well, however they looking terrible, cracked, faded, missing the little cover things, and were about 50% corrosion. Both still had 9.7 volts I took them out, bought a couple of Wal-Mart cheapo batteries, and they lasted all of 2 weeks. And they won't take them back. Now I've got a couple of Exide's, but I haven't had a chance to see if they're any good, since between taking the cheapos out and putting the Exide's in, the starter died.
I originally had a Napa battery in the Blazer, then one day it just wouldn't turn over, Took the battery to Napa, they gave me a free replacement, Than it happened again, And took it back to Napa again, and they gave me another free replacement. And guess what. That time I went and got a Wal-Mart Whatever-start and that's been fine for over a year now.
Now my mother's Trailblazer needs a battery, admittedly, She hasn't bought a new battery since she bought it about 6 years ago. I took the old one out, and I have no idea it was starting her car with 3.1 volts. And, I have no idea what it is. It has no manufacturer decals on it, just a black plastic box with a single warning label telling me not to drink the acid.
Much to my dis-approval, she bought one of the $40 Wal-Mart cheapos. We'll see how long that lasts.
