I go through batteries every two years no matter how much I spend on one. I did have my charging system crap out and replaced, but batteries are pretty much junk anymore. I gave up trickle charging them, I just budget for a new battery every two years, sometimes get three out of them but it isn't worth the worry...
Rhino,
is this on your daily drivers or cars that sit? I started just disconnecting the batteries when parking for extended periods and have gotten 7-10 years out of them. That may no longer be true though as I have heard the Battery MFr's (mistype 🙄) have been cutting costs by decreasing the internal pates etc.
I was specifically talking about my 91 Softail Custom Harley-Davidson I have owned since new. I have tried every imaginable battery made for these bikes, lead acid, AGM, and whatever new technology that has come out since I bought it and still have to get a new one every couple of years. Like I said before, no matter what I do or use that is the fact, they just do not last...
