Kinetic capacitor life span
Yes you should expect more than 10 years of operation from a Kinetic rechargeable battery (it used to be a capacitor at the origin). The only piece of advice I find useful is not to let the watch fully discharged for a long period of time, it might not recharge again or at least lose part of its capacity.

batteries
In my understanding, theoretically, when an uncharged capacitor is connected directly to a battery of, let''s say, 9 volts, instantly the capacitor will be charged and its voltage will also become 9V. This will happen because there is no resistance between the capacitor and the battery, so the variation of current by time will be infinite.

Reading Battery Voltage with the STM32''s ADC
Our first step is designing an STM32 board with a battery charger, a battery connector, and an ADC connection to read the battery''s voltage.

Battery measurement with Capacitor Voltage Divider & ADC
Resistor to Vdd, Capacitor to 0V, junction of the two to a GPIO pin via a small resistor (1k or so) Allow the capacitor to Vcc and leave it there most of the time, so it won''t take any current. When you want to know the battery voltage, use the GPIO pins to discharge the capacitor via the 1k resistor, then measure the time it takes to recharge to a threshold voltage.

Physics A level revision resource: Introduction to capacitors
Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference. A capacitor can take a shorter time than a battery to charge up and it can release all the energy very quickly.
