A vehicle battery electrical system tester with a hand-held remote control can include a vehicle battery electrical system tester with a radio frequency transceiver and a remote control unit with a radio frequency transceiver. Preferably, the vehicle battery electrical system tester and the remote control unit both include a radio frequency integrated circuit transceiver microchip. In addition, each can include a microcontroller coupled to the transceiver to control the transceiver. Furthermore, each can include an antenna, preferably an integrated circuit antenna. The remote control unit can include a visual display device, such as an LCD display, and an input device, such as a keypad.
