That is what I was thinking. I know the sellers claim these batteries come precharged but how does one know when that was? I am so sick of battery issues. I just want one that will not crap out on me in less than 2 years. I could understand it if I did not maintain mine with a tender.

I've found that the best life comes if you keep them topped off but not continuously on the charger. I charge all my "summer" batteries 3 or 4 times during the winter and get what I consider better than expected life. I put a battery in my Thunderbird in 2012 and it was still going strong when I sold it last fall, over 6 years later. It was a Power Tec AGM battery.

That's the whole point of a tender, it's not a constant charge, it only does what's needed to keep it optimum. Batteries are so inconsistent it seems. I got 10 years from my factory HD battery, which was always on the tender. Then others say they only get a few years.

Another reason for not keeping them on all the time is, according to a fire fighter friend, the number one cause of garage fires is battery chargers.

Yes I can remember back then I would buy a Diehard battery for a car and never have to think about my battery again.

I think we can all agree on that. But, why is it, with all the advances in battery technology, they still "just don't make them like they used to"?
I remember when you could buy a Deka aircraft battery for about $60.00 and it lasted 10 years. Now, Deka is out of the Aircraft business, an equivalent battery costs $250 and you're lucky if it makes it to 3 years.
