Replacing batteries with capacitors in battery based Dashcams
Firstly, we need to understand the difference between how batteries and capacitors charge and discharge their energy. A 12v car battery is considered fully charged at around 12.6 volts and considered flat at around 11.6 volts. In comparison, a 12v capacitor is fully charged at 12 volts and flat at 0 volts.
How do capacitors and batteries affect Equivalent Resistance?

Batteries are like capacitors? : r/ElectricalEngineering
Batteries aren''t really like capacitors at all aside from the fact that they can store energy. Capacitors are not used for energy storage they same way that batteries are (aside from super capacitors maybe), instead they can be thought of as buckets that can store small amounts (compared to a battery) of energy to supply extra current when switching on a chip occurs (i.e

What happened to super capacitors? : r/AskEngineers
Quite a few instruments out there that, sure they''re a three plus decades old, but the electrical specs are still excellent and you can always use RS-232 or GPIB to zombie mind control them. Some cams have batteries, but the super capacitor ones perform much better in places that get extremes in the weather.
What about a cheap battery plus super capacitors???
Years ago, a number of people did research and experiments (published on YT) about replacing your car battery with a hybrid system that used a much smaller and cheaper
kWeld vs Super Capacitor Spot welder : r/batteries
The super capacitors and the 40Ah LTO cells actually look very similar in shape and size, but they are very different in chemistry and capacity. Having a 1000F Super Capacitor bank would go great with an LTO battery pack, and it would be even better when used to smooth out voltage in a LiFePO4 battery pack and stop voltage drop.
Old capacitors
Makes sense why the batteries in em are pushing 40-50 years old (and somehow not leaking) from the esthetics of a 1935 radio more than peering in the bottom only to find modern poly or orange drip drop capacitors. What many do is warm the old cap with beeswax until the wax flows and push the guts of the cap out of the cardboard tube. Then

Converting my old go kart to electric for my son. Can I
As mentioned, I have my old go kart frame that had a 5hp gasoline engine (long gone) and I want to convert it to electric with the following motor and battery. With the price of these batteries, I wondered if a capacitor bank would improve longevity by taking the blunt of the takeoff drain and/or assisting when the load jumps like going uphill.
EV batteries could last much longer thanks
Researchers crack new approach to batteries that could help common electrics last nearly 20 times longer between charges (Image credit: ktsimages/Getty Images).
Replacing electrolytic capacitors in vintage electronics
I''ve taken up restoring 20 - 30 year old computers and other electronics in the past couple of years and one of the first things I learned here on Reddit was the importance of replacing all the electrolytic capacitors when dealing with equipment of that age.
Care for a Mac Plus
As time and Mac models came and went, the old 523 became difficult to find. Batteries Plus, the specialty battery outfit, does not carry the 523 or its Ray-O-Vac equivalent. When my 523 died, Batteries Plus took 3 "1/2 AA" size 1.5 volt batteries and encased them in series using shrinkwrap thermoplastic. Presto!
Will Old Capacitors Drain Your Car Battery? Troubleshooting Capacitor
Old Capacitors Cause Battery Drain: The myth that old capacitors drain car batteries is popular but misleading. Capacitors do not consume power like batteries; they store energy for short bursts. A failing capacitor may not hold a charge effectively, but it does not directly cause battery drain. Instead, it might indicate underlying electrical

6 FAQs about [Old batteries plus capacitors]
What makes a supercapacitor different from a battery?
Supercapacitors feature unique characteristics that set them apart from traditional batteries in energy storage applications. Unlike batteries, which store energy through chemical reactions, supercapacitors store energy electrostatically, enabling rapid charge/discharge cycles.
Do batteries store more energy than supercapacitors?
Batteries will have a higher energy density meaning that they can store more energy than supercapacitors but have a latency transferring the chemical energy into electrical energy.
Can you use a capacitor instead of a battery?
Disadvantages of the batteries are: Can you use a capacitor in place of a battery: In short - no. The issue is that the applications om which we use batteries rely on the battery’s capacity to power the application. In vehicles the starter will continue to pull power until the car starts which could be some time depending on the engine.
What is the difference between a battery and a capacitor?
The big difference is that capacitors store power as an electrostatic field, while batteries use a chemical reaction to store and later release power. Inside a battery are two terminals (the anode and the cathode) with an electrolyte between them. An electrolyte is a substance (usually a liquid) that contained ions.
Can a battery store more energy than a capacitor?
Today, designers may choose ceramics or plastics as their nonconductors. A battery can store thousands of times more energy than a capacitor having the same volume. Batteries also can supply that energy in a steady, dependable stream. But sometimes they can’t provide energy as quickly as it is needed. Take, for example, the flashbulb in a camera.
What is the difference between a lead-acid battery and a supercapacitor?
The standard lead-acid based battery is heavy, has limited cycle life, and needs a good amount of time to re-charge but is capable of sustained energy discharge, high storage capacity, and voltage stability. Let’s take a brief look at how these units work and the pros and cons of each. The Supercapacitor
