I had a Napa branded battery that lasted OK - maybe 5 years. but it was only like $100, so not too bad. Maybe I'll try Deka next - you'd think for $300, you'd get at least a year out of a battery, lol. I don't mind paying more if I can get one that doesn't die in a couple years..
I can't even blame letting it sit this time, as I was driving the E30 regularly. It maybe didn't get driven for 2-3 days, which shouldn't be enough for the battery to go flat, much less as dead as it was (4-5v IIRC). At first I thought maybe I had a drain, but the battery drains itself even disconnected from the car, and I can still charge it to 12v. So I'm pretty sure it's just crap.

That does seem accurate based on my reading today, but we can safely say that they probably do not produce Advance or Auto Zone house brands. I have also been very happy with the one Deka I bought. Then again, all of my current vehicles are running Clarios products, and they are both over 3 years old, so they'd technically be Johnson Controls manufactured.Seat Shocks....I have passed the baton to John Christy from Ninestitch.

Nando...warranty that Yellowtop! They are too expensive not to, especially after only 6 months! Also, that Deltran battery tender I used kills batteries. I too used to keep cars on a tender for months and the batteries would fail prematurely. I thought perhaps it was a defective battery until it kept happening. It killed a Yellowtop out of warranty! I think the tender isn't float charging (perhaps it wasnt designed for AGM) so I got a modern smart charger for AGM's. It has an LCD display that tells you what it's doing. To be safe, I don't leave it connected for more than a day just to make sure it doesn't overcharge the battery, then either charge or drive the car every week. This practice has been working for me. You can also put the tender on a timer if you aren't around to unplug it.Last edited by reelizmpro; 02-17-2022, 11:48 AM."I'd probably take the E30 M3 in this case just because I love that little car, and how tanky that inline 6 is." - thecj
