OBDII Battery Replacement Assistant.

Car batteries typically last about three years. When replacing a battery, removing the battery from the vehicle will cause the entire vehicle to lose power. Some modules in the vehicle will lose memory and data after losing power. Therefore, an external battery is required to maintain continuous power during battery replacement to prevent module reconfiguration or the illumination of fault lights. This cable provides external power during battery replacement.
