I drained my Norsk Lithium marine battery down, and now it won’t accept a charge.

You can either use our built-in wake-up function on our Norsk Lithium Evo-Tec chargers, or you can connect another battery of the same voltage with all connections removed, red to red, black to black to jump the battery. This will donate voltage from the second battery and bring up the voltage level for the charger to start a charging cycle. You can use another battery chemistry as long as the voltage is the same. Example: A 12V lead-acid marine battery can jump a 12V lithium marine battery.
