How Capacitors Work
A standard alkaline AA battery holds about 2.8 amp-hours. That means that an AA battery can produce 2.8 amps for an hour at 1.5 volts (about 4.2 watt-hours — an AA battery can light a 4-watt incandescent bulb for a little more than an hour). Let''s call it 1 volt to make the math easier.
Electrolytic capacitors determine the lifetime of a power supply
That means that the lifetime doubles for each 10°C reduction in temperature, so a capacitor rated at 5,000 hours at 105°C would have a service life of 10,000 hours at 95°C and 20,000 hours at 85°C. ... It assumes 24/7 operation when converting the service hours to service years. Equipment with a less intense mission profile – such as ...
