Profile: Calright Instruments specializes in providing electronic test equipment, used test equipment or refurbished test and measurement equipment. Our battery testers can test battery types such as alkaline, lead-acid, Ni-Cd, NI-MH, Lithium, Lithium-ion, and Lithium polymer. Smaller equipment such as portable telephones, video cameras, notebook computers, or communication headsets also depend upon evaluations of battery performance. Electrically-powered vehicles such as forklifts or passenger vehicles that use sealed battery systems can benefit from easy-to-do maintenance checks of battery performance.
