The ZTS MBT-LA2 Accessory Kit helps you get the most out of your MBT-LA2 battery tester. ZTS knows you don't always have a free hand or the most convenient working environments, that's why they developed this simple, yet effective kit for using and protecting the MBT-LA2 no matter where you find yourself. A soft case with a hook and loop flap keeps the tester safe from dirt and dings, scratches, and the other negative outcomes of impact. The included hanging strap allows you to hang the tester from pipes, ladder rungs, and other elements in your immediate area. If there's nothing to hang the strap to, the included magnet will attach the battery tester to metal surfaces.
