Try using an inexpensive dumb charger from HF at 2Amps for a loong time. You may get lucky.
X2 your charger is not reading enough voltage to activate the "smart " circuits to identify polarity and or if its a 6 or a12 volt batt.
Sometimes if you use jumper cables to parallel a charged batt you can get enough charge into a dead batt to get the charger going.
Good Luck, Mike
For sure.
I have done this more than once so I keep a 6/12 volt 2/6 amp manual charger since the "smart chargers" can go dumb on dead batteries. :)
Running a battery down and it setting for a while is not IDEAL but seldom is the end of the road for otherwise healthy batteries I have found over the years.
Let us know how it goes. If you have a set of jumper cables but no manual charger ($30 at Tractor Supply) you can trick your smart charger to working with the jumper cables letting the charge see the 12v from the jumping battery. There is no reason to have the engine running to do this. After the charger starts charging for a couple minutes you should be able to remove the jumper cables it it keep working.
