There is only two battery manufacturers I believe, Johnson controls and I forget the other so yeah life just sucks and last year they lowered quality to keep cost down
Good thing to do for things sitting in the shed for really long periods of time is to pull the radio fuses and what I do is take old chargers for things you don't use anymore ie. rechargeable lights or strange things like that are rated 12v and I think I even have one that was a cell phone charger. I put long speaker wire in them and attach a cigarette lighter hookup on them, make it long enough to get the plugin part out the door of the tractor. Makes it easy to start stuff up especially if you want to fire something up in the middle of winter to bring it in the shop or some strange short notice thing that pops up
