Will Tekonsha Trailer Battery Charger Fully Charge a Dead Battery through the Trailer Connector

Question:

If my battery is fully discharged, will the Tekonsha 2024-07 fully recharge the battery with the only power supply being my truck 12V battery?

A fully discharged battery might require a little extra assistance in order for the Tekonsha charger # 2024-07 to take effect. Bad things can happen to batteries once they are totally dead. We do have some pretty substantial battery chargers that can revitalize a battery, like # CTEK56353. But even this charger cannot save a battery if it is too far gone.
