WHAT CUSTOMERS SAY.
“I was pleasantly surprised by how neat the green connector and battery clamps looked when I opened the package. Our car needed a new 12V battery, so I checked the vehicle manual and had the memory-saver lead used with a suitable backup source while the battery was being replaced. I especially liked being able to see the voltage reading on the small digital display before the work started. The 135 cm cable gave us useful room to position everything, and the compact OBD II plug made the setup feel nicely organised. It's a clever little accessory to keep with my car-care tools.”
