> LR44 starting voltage is about 1.500 Volts. SR44 starting voltage is about 1.550 Volts. Both are rated as 150 mA hours, but the discharge curves give very different operational life depending on the required voltage for the application. The LR44 voltage drops over the duration of usage. The SR44 remains flat (and above 1.5V) for most of its useful life. The calipers need at least 1.25 to operate.
> The LR44 drops below 1.3 Volts after about 50% usage. The SR44 drops below 1.5 Volts after about 95% usage. The SR44 start at a slightly higher voltage, and their flat discharge curve makes them far superior for low power, long operational life applications, like a caliper.
