Battery testers with secondary functionality

An electronic vehicle tester, comprising:

• a tire tester for use by an operator to couple to a tire of the vehicle and configured to receive a tire parameter of the tire of the vehicle, the tire tester including, a user input to receive an input from the operator and radio frequency (RF) output configured to wireless transmit the tire parameter;
• an electronic battery tester, comprising;
• first and second Kelvin connections configured to couple to terminals of a battery of the vehicle;
• a forcing function source configured to apply a forcing function to the battery through the Kelvin connections;
• a microprocessor configured to test the battery based upon the response of the batter to the forcing function;
• a memory;
• and
• a radio frequency (RF) input configured to receive the RF output from the tire tester which contains the tire parameter.
