Battery Corrosion

As I said above agm would be your best bet for not having that happen.  They do cost more though.  Charge it however you want because you paid for it.  I just know that having something charging all the time will reduce it's life.  I get 6-8 years out of mine not leaving on a tender.  I also buy AGM now instead of lead acid.  If your getting off gasing that is a problem unless it's for a short time.  It may have starting voltage but it does reduce the amp hours available over time.  I can prove it but most will just buy a new battery every 3-4 years.  On lead acid look up desulfication.  Advanced systems can pulse and vary the voltage to clear off the crystalization.

They used to say " Don't store a battery on concrete

Yeah that was old school I think that myth has been debunked.

Leaving a battery tender on 24 / 7 / 365 is not a good idea

Disagree Richard ... I've got cheapies on tenders and going on 10 years old now. Yeah ones not on tenders go about 5 tops. 

2016 Kubota SxS always on a tender and still load checks good. Same with boat batteries.

I can agree with that but most people are just buying off the shelf and plugging in.  If you do as stated in that article I could see that.  Most are happy enough getting 3-4 years out of it and buying another one.  Also bigger tractor batteries can be of better quality.  Lot of factors to consider.  I've had one battery last 14 years and never on a tender.  The average though is if off gasing then it's an issue unless for short periods.

@WHX?? :disgust: Some will disagree, but I never gave much credence to anything SOI had to say. @MikesRJ  and I discovered that much of his info was plagiarized. Since SOI has evaporated into the ether, it kind of proves my point.

I also deal in a lot of lipo batteries and have done a setup on a lawnmower that worked and charged off the engine alt.  I would never leave that kind of setup in a barn or outside because when they go up in flames good luck putting it out.  I just did it as an experiment to see if I could.  I then pulled it off because I prefer the weight and safety of a lead or agm.

That is why it is a good idea to get a bit of seat time on each one every couple of weeks rather than having then sit in the corner.

When I was an operator at a power plant we had large battery banks that powered inverters for an Uninterruptable Power Supply for vital equipment. Every month each battery bank would be taken out of service and placed on a load to cycle the battery down and then returned to service on its charger. Cycling the batteries prolonger their life.

I just replaced the battery on the GT-14 which was new in 2009, it never saw a tender but never sat unused more than a couple weeks,  just the luck of the draw.

Might be on to something there Richard. Dan says it's best if you just run them.
