on the subject of tractor batteries: highly suggest sealed (non serviceable). recently replaced the factory battery w/removable inspection plates...fluid always splattered onto the tray regardless of water level in cells. so now i always use sealed batteries for tractor use.
Is a fully discharged battery now junk?

I'm the OP and will put the battery back in the tractor today and high charge it through use. Then will try to find a higher charge battery charger from a neighbor.
I'll get through this one and study-up on batteries and their characteristics. Thanks for all the help.

I have one of these Noco Genius chargers. It would take overnight, but I think it would recharge that battery. Amazon.com

That is battery maintainer (1 amp) not a charger
Whether or not a wet cell battery will recover from being fully discharged, depends on a number of factors.
If the battery isn't already weak and near the end of it's useful life, you can usually get them to take a charge, and return it to service.
If it won't take a charge, you can sometimes use a manual mode charger to get it to start taking one, and or, a charger with a rejuvenation setting.

Hi scootr,
I have charged dead batteries with it overnight. I switched over from my big chargers because this one doesn't cook my batteries.
The product description says: "Charge dead batteries - Charges batteries as low as 1-volt. Or use the all-new force mode that allows you to take control and manually begin charging dead batteries down to zero volts."

Noco 5 Genius charger here - that thing is a heck of a good charger - brought life back to a 2 dead cell battery - Not great capacity in the one cell but it works at 12v

I'm not positive, but I accidentally turned on the fuel solenoid on my backup generator and it sat that way for several months. Deciding to exercise it due to a forecasted storm. This was spring/summer temps.
2 or 3 days on a low charge brought it back up to 12+ volts but the amperage was low.
It was only 2-3 years old and due to its use in the backup generator, it got replaced.
