CR2016 type battery1, Model CR2016 button-type battery
This type of button batteries in today’s car key remote usage is very high, almost one of the most versatile remote control car battery. Such Battery voltage is 3V, general use car keys are 9V battery powered, so every time I change the battery when the battery is three full replacement.For example, the wide, Toyota, Volkswagen, Mazda and so on remote control models. CR2016 type specifications: cell diameter of 20mm, a thickness of 1.6mm.
