[TR] Battery troubles

 The desulfate mode only kicks in when the battery is deeply discharged.  With these new batteries a deep discharge condition will make the battery suspect.  They don't tolerate this well at all.

My only issue was with a Motorcycle battery.   I think the charger I was using was trying too hard to desulfate and killed the battery (only 2 years old).  Since then I only plug in the bike for a few days each month.  All the rest I have left plugged in for long periods of time without issue.  My chargers are "smart" but not so smart that they will tell me a battery is bad.  That being said, I have had a few batteries go bad in the past few years.  The last few I have bought for various vehicles only seem to last about two years.  I tried expensive ones and cheap ones, none seem to make it past 24 months.  It may be just that the batteries being sold these days are junk.  The one in my Spitfire is almost 10 years old and still starts the car every time.

My Tr4 hasn't gotten out at all this summer.   I put my new battery charger on it -  It's all electronic  vs my old one that just had a 3 position switch and an analog meter.
This new charger is quite fancy, it will tell you if the battery is connected backwards,  light a light with a bad battery, etc.  Trouble is I"m not sure I trust it.
I've had this thing tell me 4 batteries are bad.  I havent been driving my truck, my wife hasn't been driving her Z4,  and my mom's car battery showed bad as well....
I think I'm going to buy an old school charger and see what happens.  It's cheaper than buying one of the four batteries....
Or they just sat so long they died.....     Anyone have experience with those newer fancy chargers?  Any issues or concerns?
