Why use a Super Capacitor? Super Capacitors (Super Caps) are the next generation energy storage with advanced performance where it matters most. They have a lifespan of more than 30 years with no capacity degradation. A high charge and discharge rate with more than 98% round trip efficiency at a 100% depth of discharge make Super Caps the most efficient way to store
Supercapacitors are ideal when a quick charge is needed to fill a short-term power need; whereas batteries are chosen to provide long-term energy. Combining the two into a hybrid battery satisfies both needs and reduces

The Baghdad Battery is the name given to a set of three artifacts which were found together: a ceramic pot, a tube of copper, and a rod of iron. It was discovered in present-day Khujut Rabu, Iraq in 1936, close to the ancient city of Ctesiphon, the capital of the Parthian (150 BC – 223 AD) and Sasanian (224–650 AD) empires, and it is believed to date from either of these periods.

Charging capacitors up to a high voltage that can be a hazard. That would be north of 70V. Super caps can be hazards due to molten metal sprayed if you short them. ie burn hazards. The cost of super caps is around 2x higher than batteries and 10x less energy density. So they are not a favourable solution to energy storage.

A 1 farad capacitor was considered to occupy a huge space of the order of a room when electrostatic capacitors were in vogue. This is because a 1 farad capacitor is a large unit. Today, ultracapacitors are made in the Farad range, and capacitance values of 10 F to 3000 Farads are readily available.

and you need a 214 Farad supercap with a voltage rating of 3.7 volts minimum. EDIT - As Brian Drummond has pointed out, supercaps often have a high internal resistance. If you want to take this into consideration (and you had better do so), you need to quantify the resistance R of the cap at the current level which you are using.
In March 2012, Professor Elizabeth Stone of Stony Brook University, an expert on Iraqi archaeology, returning from the first archaeological expedition in Iraq after 20 years, stated that she does not know a single archaeologist who believed that these were batteries.
Now plug in your own numbers. EDIT : Be aware that some supercapacitors have a relatively high ESR, or series resistance, perhaps 10 or 50 ohms. At 1 mA, that would reduce the available voltage by 10 to 50mV, but at higher currents this gets more problematic.
