    No. Applying incorrect polarity to a battery can potentially ruin both the charger AND the battery. Plus you run the risk of a fire if there aren't enough safety features in your charger unit such as a fuse or circuit breaker.

    You will blow the battery up, get acid all over you and have a hospital bill. A new battery will be around $30.00. Depending on the cold crank amps.

    Nope.

    MOST chargers today will NOT even TRY to charge a battery backwards.

    They simply spark and shut down until connected correctly.

    It's already been made clear: don't try it, you'll probably have big regrets.
