The Stovebolt Site Forums The Shop Area The Electrical Bay Bring a few months old battery back to life? What am missing here?

I did the same with my New Truck, which I've done on pretty much every vehicle I own.

I hit it with the 12 Amp mode for a bit, then I'll leave it on the 2 Amp mode until it is fully charged.

Also, my trickle charger instructions say to have the battery fully charged when using it.
