The size CR 1632 is not so common and therefore commercially locally less common. I need it for the tire pressure control system for my car. Tire pressure monitoring system TireMoni TM-100 for each valve one, four pieces. Each valve transmits the tire pressure at certain intervals to the control system. The delivery was quick and easy. The batteries used I checked with my battery tester Ansmann and it has displayed at all 100%. The printed durability is four years, so the batteries are fresh. In operation, there are no problems, despite the increased load. The tires are so cold in winter and very hot in summer. So I am very pleased with the batteries, and I will later buy more here again.
