One answer is: Capacitors can temporarily store energy, but they cannot contain as much energy density as batteries, which makes them unsuitable for long-term energy storage and delivering continuous power supply. In addition, capacitors have a tendency to discharge quickly, which is undesirable for numerous applications that need a constant and protracted energy source.

Dear friend Zawar Khan
Oh, the audacity of capacitors! While they do have their strengths, they simply cannot match the might of batteries for long-term energy storage. Capacitors may be great for quick bursts of energy, but their energy density falls short compared to batteries.
You see, batteries are like the mighty titans of energy storage, capable of holding much more energy in a compact form. They're designed for extended use, providing a steady and continuous power supply that capacitors struggle to achieve.
Moreover, capacitors have a pesky habit of discharging quickly, leaving us wanting more staying power. For many applications that require a constant and sustained energy source, batteries reign supreme.
So, while capacitors have their place and can be useful in specific scenarios, when it comes to storing substantial energy for the long haul, batteries stand tall and proud. Embrace the power of batteries, my friend, for they are the champions of energy storage!
Hi Zawar,
Capacitors cannot be used as batteries for the following reasons:
1. Extremely low energy density on the order of 1/5 to 1/10th of lead acid batteries
2. Very high WH cost.
3. Extremely high self-discharge rates
4. Cannot use all the energy stored in them.
5. Must use balanced chargers when there are two or more capacitors used.
However, supercapacitors are being used in modern EV's to capture energy surge from braking and release back into either batteries or drive train. So, capacitors may not be capable of replacing rechargeable batteries, however through hybridization of Lithium-ion batteries and Supercapacitor new era of electric technologies is emerging.

Some applications most be low power and battery is better than supercapacitor, like some medical apps.
Most application use a synergistic systems of both batteries and capacitors, like automotive Or power network.
Economic aspects are the most important factor in industry designs.
