Most chargers have some sort of protection for reverse polarity, unless the battery was truly black flag dead. If it had much of any charge at all, I''m sure it would have tripped the breaker in the charger. I''d check it with a multimeter and see what it says for polarity. The meter will display a minus sign when polarity is reversed.
Battery Positive and Negative Side: Explained and How to Identify
Polarity: The negative side of a battery is the pole that has an excess of electrons and is connected to the positive electrode.

"Ground" vs. "Earth" vs. common vs. negative terminal
A. The positive terminal in a circuit is what creates voltage. Voltage is a potential, so given that it is the positive ions in, say, a battery, which are generally fixed in place, it makes sense that the + terminal in a circuit would create voltage.. B. The negative terminal in a circuit is what provides current. Current is the flow of electrons, and that flow is towards the terminal that …
