The invention herein relates to a non-polarity charging device wherein the positive/negative sensing terminals are connected to the battery. When in correct polarity, current flows from positive output clamp output to the battery positive terminal and back to the charging device through the negative output clamp, otherwise, the positive voltage flows through the negative output clamp to the battery positive terminal. Also, even when the battery voltage is below the sensor reading threshold, the manual switch at both battery terminals force-feed electric current through the correct polarity conducting circuit, with positive voltage at the positive clamp output, supplying positive current to effect a complete charging circuit. When the polarity sensing is completed and charging begins, a current indicator circuit lights up to reflect that the charging device is functioning.
