Double ditto bcredliner on the above quote. That's the ONLY time I use my charger's 50 amp setting. Its when the battery is dead, and I need to get the vehicle started NOW...and hit the road.

But if my battery was discharged due to some unfortunate circumstances...or it's getting old and voltage is dropping...I use the low & slow recharging method to see if that revives the battery.

To the OP:
You may want to also start monitoring your battery if it fell into a state of deep discharge. Many times this can cause irreversible damage that it will never recover from. IF you've unlocked your OBC...you can quickly (like in 15 seconds) run OBC TEST 9 with the ignition in position 1 (hopefully BEFORE starting the engine) to get an idea of the battery's voltage. If it is consistently below 11.89 volts...it's a sign that the battery is not in the best of health because at 11.89 volts...the battery is a 0% state of charge.
